Speed up Booting Xp by 70 Times !!

Whenever you start your computer, you are faced with a few moments of thumb twiddling while Windows XP boots and prompts you to log on. Although you should expect to wait for a few moments, sometimes Windows XP seems to boot rather slowly. In fact, you may notice that over a period of time the PC that used to roar to life seems a bit sluggish instead. Fortunately, you can perform several techniques that help Windows XP get the bootup speed you want. This Article explores how to put these techniques to work.


Stopping Unneeded Startup Services !


Along with the core operating system and programs that Windows XP runs when it starts, there is also a host of services involved. Many of these services are necessary for Windows XP to operate correctly. However, many of them are for features in Windows XP that you may not use at all. You can peruse the services and disable any service that you do not want to run. The fewer services that run, the more quickly Windows XP will boot.

Caution:

Exercise caution when stopping services. If you do not know what a service does or are unsure of the ramifications of stopping the service, leave it alone. Some services are critical to Windows XP's operations, so make sure you understand what the service is before you disable it.


To reduce the number of services that start on bootup, you can access two different areas of Windows XP. The first is the System Configuration Utility. The Services tab shows you the services that start when the computer boots.
You can stop a service from starting by simply clearing the check box next to the service and clicking OK. However, before you do so, there is another way to disable services that you may prefer because the interface gives you more information about the service in question.


Open Control Panel/Administrative ToolsServices or else select Start/Run, type services.msc, and click OK. Either way, you see the Services console.
I prefer to use the Services console instead of the System Configuration Utility because it describes what the service does. Additionally, you can double-click a service and examine its properties.

Notice the Startup Type column in Figure 4-2. This information lists whether the service is automatic or manual. Manual services are only started in Windows XP when you start a process that requires the service. Some other process may require the service that has a "dependency" relationship with it; in this case, the dependency service will start, as well. Because these services do not start automatically when you boot Windows XP, you do not need to do anything with manual services.


However, all services listed as automatic start when Windows XP boots. These are the services that increase boot time. As I have mentioned, many of them are necessary and important, so you should not stop automatic services from booting unless you are sure of the ramifications. You can get this information by looking at the Description column. Here's a quick look at common services you may want to live without:


SPEED UP BOOT BY DISABLING UNUSED PORTS.!!


You may have tried many tweaks like modifying windowsXP start-up applications, prefetches, unload DLLs method,etc. And yes those methods do work for me.
I have just accidentally found out another way to give you an extra boost in windowsXP's boot performance. This is done by disabling your unused devices in
Device Manager. for example, if you don't have input devices that are connected to one of your USBs or COM ports, disabling them will give you an extra perfromance boost in booting. Go to Control Panel -> System -> Hardware tab -> device manager Disable devices that you don't use for your PC and then restart.


Do Dis !!

1.Start Registry Editor (Regedit.exe).

2.Locate the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\MemoryManagement\PrefetchParameters

3.Make sure you backup the keys by exporting them to a .reg file.

4.On the EnablePrefetcher value, change the setting from 3 to 5 (decimal).

5.Close the registry editor.

6.Restart your computer


Automatic Updates !

This service enables Windows XP to check the Web automatically for updates. If you don't want to use Automatic Updates, you can disable the service. You can always check for updates manually at the Windows Update Web site.

Computer Browser: If your computer is not on a network, you don't need this service. If you are on a network, leave it alone.

DHCP Client: If you are not on a network, you do not need this service. If you are on a small workgroup, you can still increase boot time by configuring manual IP addresses (which I explore later in this chapter).

DNS Client: If you are not on a network, you do not need this service. If you are, leave it alone.

Error Reporting and Event Log: You don't have to use these services but they can be very helpful, so I would leave them configured as automatic.

Fax: If you don't use your computer for fax services, you can disable this one.

Help and Support: If you never use the Windows XP Help and Support Center (found on the Start menu), you can disable this service.

IMAPI CD-Burning COM: This service enables you to burn CDs on your computer. If you never burn CDs, you can disable the service.

Indexing Service: Your computer keeps an index of files but if you rarely search for files, the service is just a resource hog. You can stop it and turn the service to manual.

Windows Firewall/Internet Connection Sharing: If you do not use these features, you can disable them.

Infrared Monitor: If you do not use infrared devices, you can disable this service.

Messenger: This service sends alert messages on a local area network (it is not the same as Windows Messenger). If you are not on a network, you can disable this service.

Print Spooler: If you do not do any printing from the computer, you can disable this service. If you print, make sure you leave it as automatic.

Remote Registry: This service allows remote users to modify the Registry on your computer. If you are not on a network, you can disable this service.

System Restore Service: This service allows you to use System Restore. If you have turned off System Restore anyway, you do not need to turn off the service. If you do, you turn off System Restore.

Themes: If you do not use themes, you can disable this service.

Windows Image Acquisition: If you do not use scanners or digital cameras, you can disable this service.

Wireless Zero Configuration: If do not use wireless networking devices, you can disable this service.




You may have a number of other automatic services, depending on software and other configurations on your computer. So it's a good idea to look through the services and learn more about them. If you double-click a service, a Properties dialog box appears
Notice that on the General tab, you see a Startup Type drop-down menu. If you want to change an automatic service to manual, select Manual here and click OK. As a general rule, don't disable a service unless you are sure you will never use it. However, manual configuration allows the service to be started when you find it necessary, thus speeding up your boot time.
However, before you change a service to manual, look at the Dependencies tab (see Figure 4-4). This tab shows you which other services depend upon the service you are considering changing.
Keep in mind that services are necessary for the vast functionality you get with Windows XP. Change only those services that you understand and do not use. How you use your Windows XP computer should be the best guide in terms of optional startup services.


Tip !


The Indexing service and the System Restore service take up a lot of disk space and system resources across the board. You can live without the Indexing service but I suggest that you keep using System Restore. It works great when you are in a bind and this is one case where the loss of speed may not be worth the ramifications of not using System Restore.


Speed Tips and Tricks for Windows XP Startup
Aside from startup programs, services, and the Prefetch folder, there are a number of other startup procedures and issues you can modify to help Windows XP start faster. The following sections explore those tips and tricks.


Manual IP Addressing on Small Office/Home Networks
Windows XP is configured to help you take care of networking. It uses the TCP/IP protocol for networking in workgroups, or what you might call small office or home networks that do not use a dedicated server.

The problem is that automatic IP addressing can be slow. When your computer boots, it has to query the network to see what IP addresses are already in use and then assign itself one. If you want to speed up the boot time a bit, consider manually assigning IP addresses to all computers on the network. This way, the network computers do not have to worry about locating an automatic IP address. Because one is manually configured, the operating system doesn't have to spend time solving this problem.

This isn't a networking book, however, so I won't delve into the implications of using a manual IP address, but if you are using a computer that functions as a host computer to the Internet (using Internet Connection Sharing [ICS]), you can get into connectivity problems if you change the configuration of the IP address. However, you can still work around this problem by starting with the ICS host computer.

Select Start/Connect To/Show All Connections. Right-click your network adapter card and click Properties. On the General tab, select TCP/IP in the list of services and click the Properties button.

In the TCP/IP properties, you can see if you use an automatic or manual IP address. In the example in Figure 4-5, I have configured a manual IP address of 90.0.0.1 and a default subnet mask. The other computers on my office network each use a different IP address in the same class, such as 90.0.0.2, 90.0.0.3, 90.0.0.4, and so on. This way, each computer has a permanent IP address, which helps increase boot time. Note that if you change the IP addresses of your computers, they must all use the same subnet mask. A default subject mask of 255.255.255.0 will keep you in good shape.

Make sure you understand the implications of changing IP addresses on your network. If you have no networking experience at all, you may be wiser to leave the automatic IP addressing as is and try to gain some speed using the additional suggestions in this chapter.


Disabling Recent Documents History !


Windows XP includes a feature that keeps track of all recent documents you have opened or used. The idea is that you can select Start/Recent Documents History and quickly reopen any document you have recently used. I use many documents each day and never use the feature myself. In my opinion, I can keep up with what I want to use without Windows XP doing it for me.
The bad thing about Recent Documents History is that Windows XP has to calculate what should be put there each time you boot Windows, which can slow things down. So, if you never use the Recent Documents History, it's a good idea to disable it. Here's how:
1. Open the Registry Editor (select Start/Run, type regedit, and click OK).
2. Navigate to HKEY_CURRENT_USER\Software\Mcft\Windows\ CurrentVersion\Policies\Explorer.
3. Create a NoRecentDocsHistory D_WORD key. Double-click the value to open it once it is created.
4. Set the Data Value to 1 to enable the restriction.
5. Click OK and close the Registry Editor. You'll need to restart the computer for the change to take effect.


Disabling the Boot Logo !


You can remove the boot logo that appears when you start Windows XP. This little tweak probably shaves only a few seconds off your boot time but seconds count if you are serious about trying to get Windows XP up and running as quickly as possible. The only negative is that if you remove the boot logo, you will also not see any boot messages, such as check disk. (But if you are not having problems with your computer, this isn't such a big deal.)
To remove the boot logo, follow these steps:
1. Select Start/Run, type msconfig, and click OK.
2. In the System Configuration Utility, click the BOOT.INI tab.
3. On the BOOT.INI tab, click the NOGUIBOOT check box option. Click OK.


Removing Unwanted Fonts !


One trick that increases your boot time a bit is to lose any fonts in the Fonts folder in Control Panel that you never use. The more fonts you have, the more processing Windows XP has to do to prep all of those fonts for use. You must be a bit careful here to not remove fonts that you might want, but there is a good chance that you can live without many of them. For instance, you may have foreign language fonts and other symbol fonts (such as Wingdings) that you never use.
To delete unneeded fonts, follow these steps:
1. Open the Fonts folder in Control Panel.
2. Select Edit/Select All and then Edit/Copy.
3. Create a new folder on your desktop, open it, and select Edit/Paste.
4. In this new folder, delete any of the fonts you do not want.
5. Return to the Fonts folder in Control Panel. Right-click the selected fonts and click Delete.
6. Go back to your new desktop folder and click Edit/Select All.
7. Return to your Fonts folder and click Edit/Paste. You now have only the desired fonts in the Fonts folder.


Tip:


You can directly delete fonts from the Fonts folder without creating the secondary folder. However, I recommend the preceding steps to help ensure that you do not make a mistake in the deletion process.


Stopping Remote Assistance and Remote Desktop Sharing !


In Windows XP Professional, you have two remote networking features called Remote Assistance and Remote Desktop Sharing. These remote networking features are very helpful in a variety of situations but if you don't use them, it is good idea to disable them to save boot time. You can always enable them later if you want to use them.
Note:
If you are interested in using Remote Desktop or Remote Assistance, see my book Windows XP for Power Users: Power Pack published by John Wiley & Sons.
1. Open the Start menu, right-click My Computer, and choose Properties.
2. Click the Remote Tab.
3. Clear both check boxes to disable Remote Assistance and Remote Desktop.


Speeding Up the Dual-Boot Timeout !


If you dual-boot your computer with Windows XP and another operating system, you see an operating system selection menu on startup. If you typically boot into Windows XP and not the other operating system, you can speed up the dual-boot timeout value so that you do not wait so long for the boot process to select your default operating system and continue with the boot process. The default timeout value is 30 seconds but you can change this setting to 10. This gives you enough time to select the alternate operating system if you want but also speeds up the boot process. You can skip this section if you do not use a dual-boot configuration.
Follow these steps:
1. Locate the boot.ini file on your computer. It is a hidden file by default; mine is located in C:\boot.ini.
2. Open the file with Notepad (which is what opens it by default).
3. Change the Timeout value to 10 (see Figure 4-11).
4. Select File/Save and close Notepad.


Speeding Up Your PPPoE Connection !


If you use a Point-to-Point Protocol connection over Ethernet (PPPoE), you may notice a delay in using the PPPoE connection after startup. By default, there is a 120 second delay but you can stop this behavior by manually configuring an IP address for the network adapter card. If you do not use a PPPoE connection, you can skip this section.
1. Select Start/Connect to/Show All Connections.
2. Open the TCP/IP properties for your LAN network interface card.
3. Manually set the IP address on the TCP/IP properties to an appropriate IP address and subnet mask for your network.


Reducing the Wait Time


When you start to shut down Windows XP, it has to quit, or "kill," any live applications or processes that are currently running. So close all applications first. However, some applications and processes are always running in the background. You can reduce the amount of time that Windows XP waits for those applications and processes to close before Windows XP kills them. Edit three different Registry settings to change this:
1. Open the Registry Editor.
2. Navigate to HKEY_CURRENT_USER\Control Panel\Desktop. Select WaitToKillAppTimeout and set the value to 1000.
3. Select the HungAppTimeout value and set it to 1000 as well.
4. Navigate to HKEY_USERS\.DEFAULT\Control Panel\Desktop. Set the WaitToKillAppTimeout and set the value to 1000. Select the HungAppTimeout \newline value and set it to 1000 as well.
5. Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control. Select the WaitToKillServiceTimeout value and set it to 1000.
6. Close the Registry Editor.

Automatically Killing Tasks on Shutdown !


You know the drill. You start to shut down the computer, you wait a few moments, and then you see a dialog box asking if you want to kill an application or service that is running. Instead of prompting you, you can make Windows XP take care of the kill task automatically. Here's how:
1. Open the Registry Editor.
2. Navigate to HKEY_CURRENT_USER\Control Panel\Desktop.
3. Highlight the value AutoEndTasks and change the value to 1.
4. Close the Registry Editor.

Here's a great tip to speed up your browsing of Windows XP machines. Its actually a fix to a bug installed as default in Windows 2000 that scans shared files for Scheduled Tasks. And it turns out that you can experience a delay as long as 30 seconds when you try to view shared files across a network because Windows 2000 is using the extra time to search the remote computer for any Scheduled Tasks. Note that though the fix is originally intended for only those affected, Windows 2000 users will experience that the actual browsing speed of both the Internet & Windows Explorers improve significantly after applying it since it doesn't search for Scheduled Tasks anymore. Here's how :

Open up the Registry and go to : HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace Under that branch, select the key : {D6277990-4C6A-11CF-8D87-00AA0060F5BF} and delete it. This is key that instructs Windows to search for Scheduled Tasks. If you like you may want to export the exact branch so that you can restore the key if necessary. This fix is so effective that it doesn't require a reboot and you can almost immediately determine yourself how much it speeds up your browsing processes.

Dictionaries on the Internet..

Syzygy..
That's a real word, but what does it mean? To find out, you could pull a forty-pound dictionary off your bookshelf, fire up your dictionary CD ROM, or browse a dictionary website like Dictionary.Com. However, if you have IE4+, you can save yourself a couple of steps by installing Magic Dictionary. Using online resources will save you time, money, and...you'll never get a paper cut.

Clearing the Page File on Shutdown..

Another way to set the computer to clear the pagefile without directly editing the registry is:
Click on the Start button
Go to the Control Panel
Administrative Tools
Local Security Policy
Local Policies
Click on Security Options
Right hand menu - right click on "Shutdown: Clear Virtual Memory Pagefile"
Select "Enable"
Reboot

If you want to clear the page file on each shutdown:
Start Regedit
Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Control\Session Manager\Memory Management\ClearPageFileAtShutdown
Set the value to 1

Removing Thumbs.db Files

When viewing a folder with the Thumbnail view, WindowsXP creates a thumbs.db file.
This is a cache of the current pictures in that directory.
If you want to turn this feature off and save a little disk space
Start the Windows Explorer
Go to Tools / Folder Options / View
In the first section under Files and Folders, check Do not cache thumbnails
Now you can search for the thumbs.db file on your computer and remove them. No more should be created..

Recover the Scrath Cd's !!

Don't you feel like crying every time you add another disc to your pile of scratched discs. Trashing that disc which contained your favorite songs, pics, files, games or videos is not easy.

Read-on, if you find yourself wishing for a miracle every time your fav CD is scratched:

Home Remedy :
here's an easy home remedy, which might give you the desired results. Rub a small amount of toothpaste on the scratch and polish the CD with a soft cloth and any petroleum-based polishing solution (like clear shoe polish). Squirt a drop of Brasso and wipe it with a clean cloth.

Technology to the rescue
There are many softwares available on the net, which enable the recovery of the CD data. BadCopy Pro is one such software, which can be used to recover destroyed data and files from a range of media.

Just a few clicks is all it requires to recover the disc from almost all kind of damage situation; be it corrupted, lost data, unreadable or defective.

DiskDoctors is another popular company, which offers both software and solutions to recover data from a scratched CDs and DVDs.


General Tips:
* Always wipe the CD from the center outward with stratight spoke-like strokes. Wiping CDs in circles will create more scratches.

◘ Do not scratch the graphics layer as you cannot repair the disc. HINT: Hold the disc up to a light with the graphics layer facing the light source. If you can see light thru the scratches at any point then the disc may be irreparable and or exhibit loading or playing errors.

◘ Clean your Disc players lens regularly with a suitable product to ensure optimal viewing pleasure.

◘ Make sure to use a soft, lint-free cloth to clean both sides of the disc. Wipe in a straight line from the centre of the disc to the outer edge.

◘ If wiping with a cloth does not remove a fingerprint or smudge, use a specialized DVD disc polishing spray to clean the disc.

◘ Only handle the disc by its outer edge and the empty hole in the middle. This will help prevent fingerprints, smudges or scratches.

Statistics:
◘ Fingermarks/prints cause 43% of disc problems!
◘ General wear & tear causes 25% of disc problems!
◘ Player-related issues cause 15% of disc problems!
◘ User-related issues cause 12% of disc problems!
◘ PlayStation 2 machine scratches cause 3% of disc problems!
◘ Laser rot (a manufacturer error) causes 2% of disc problems!

Optimize your Hard-Disk !!

1. Run Notepad and open file System.ini which can be found in Windows directory,
2. When you opened this file under [boot] section change "shell=explorer.exe" into "shell=defrag.exe",
3. Restart you computer,
4. When Windows is loaded, only Disk Defragmenter will run,
5. Optimize HD and restart your computer again,
6. Before windows start to loading press F8 on your keyboard,
7. Choose "Command Prompt Only" and type "edit system.ini" (without quotation marks) and under [boot] section change "shell=defrag.exe" into "shell=explorer.exe"
8. Restart you computer once again,
9. Now your HD is perfectly optimize.

Some Registry Tricks !!

Add Open With to all files

You can add "Open With..." to the Right click context menu of all files.This is great for when you have several programs you want to open the same file types with.

1. Open RegEdit
2. Go to HKEY_CLASSES_ROOT\*\Shell
3. Add a new Key named "OpenWith" by right clicking the "Shell" Key and selecting new
4. Set the (Default) to "Op&en With..."
5. Add a new Key named "Command" by right clicking the "OpenWith" Key and selecting new
6. Set the (Default) to "C:\Windows\rundll32.exe shell32.dll,OpenAs_RunDLL %1", C:\ being your Windows drive. You must enter the "OpenAs_RunDLL %1" exactly this way.



Customize the System Tray

You can add your name or anything you like that consists of 8 characters or less. This will replace the AM or PM next to the system time. But you cannot do this if you are using any of our software during the trial period; it will corrupt the trial license.

1. Open RegEdit
2. Go to HKEY_CURRENT_USER\Control Panel\International
3. Add two new String values, "s1159" and "s2359"
4. Right click the new value name and modify. Enter anything you like up to 8 characters.

If you enter two different values when modifying, you can have the system tray display the two different values in the AM and PM.

LockOut Unwanted Users

1. Open RegEdit
2. Go to HKEY_LOCAL_MACHINE\Network\Logon
3. Create a dword value "MustBeValidated"
4. Set the value to 1
This forced logon can be bypassed in Safe Mode

Disable the Outlook Express Splash Screen


1. Open RegEdit
2. Go to HKEY_CURRENT_USER\Software\Microsoft\OutLook Express
3. Add a string value "NoSplash"
4. Set the value data to 1 as a Dword value

Multiple Columns For the Start Menu

1. Open RegEdit
2. Go to the key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\Explorer\Advanced
3. Create a string value "StartMenuScrollPrograms"
4. Right click the new string value and select modify
5. Set the value to "FALSE"

Changing Windows' Icons

You can change the Icons Windows uses for folders, the Start Menu, opened and closed folder in the Explorer, and many more.

1. Open RegEdit
2. Go to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\Explorer\Shell Icons
3. Add a string value for each Icon you wish to change.
Example: "3" ="C:\Windows\Icons\MyIcon.ico,0" This will change the closed folders in the Explorer to "MyIcon.ico". Here is a complete list for each value.
0= Unknown file type
1= MSN file types
2= Applications Generic
3= Closed Folder
4= Open Folder
5= 5.25" Drive

Introduction of IP Addresses !!

What is an IP Address?

Every system connected to the Internet or connected to a particular network has a unique Internet Protocol Address of an IP Address. Just as in the real world every person has his or her own Home Contact Address, similarly every system connected to the Internet has its own unique IP Address. Your IP Address is the address to which data should be sent to ensure that it reaches your system. The IP Address of a system acts as the system’s unique identity on the net.
Structure of an IP Address:

An Internet Address (IP Address) is a 32-bit address or number, which is normally written as four decimal numbers (of 8 bits each), each separated from the other by a decimal. This standard is known as the dotted-decimal notation.

For Example,

A Typical IP Address would be as follows: 192.168.1.1
It can be further broken down as:

192 representing the first 8-bits.
168 representing the next 8-bits.
1 representing the third 8-bits.
1 representing the fourth 8-bits.

Thus when considered together 192.168.1.1 represents 32-bits. So basically we can conclude that each decimal in an IP Address represents 1 byte or 8 bits. It is important to note than an IP Address can contain numbers from 0-255.

There are a huge number of IP Addresses in use in the present day wired age. All these IP Addresses have some sort of relation with each other and each individual IP Address can reveal a lot of secrets about the Network, of which it is a part. Before we move on to that, we need to understand the fact that all IP Addresses being used are divided into a number of ranges, which are as follows:

Class Range

A 0.0.0.0 to 127.255.255.255
B 128.0.0.0 to 191.255.255.255
C 192.0.0.0 to 223.255.255.255
D 224.0.0.0 to 239.255.255.255
E 240.0.0.0 to 247.255.255.255

We can easily conclude that one can find out the Class to which an IP Address belongs to simply by comparing the numeral before the first decimal of the IP Address with the above table.

For Example,
In The IP Address 192.168.1.1, the number before the first decimal is 192 and the above table tells us that it belongs to Class C of the range of IP addresses.

The various IP Addresses are divided into the different classes on the basis of the structure of their Network or in other words on the basis of what the various numbers separated by decimals actually stand for. To understand this, let us refer to the following:

Class Information

A It has the first 8-Bits for Netid and the last 24-bits for Hostid
B It has the first 16-Bits for Netid and the last 16-bits for Hostid
C It has the first 24-Bits for Netid and the last 8-bits for Hostid
D It represents a 32-bit multicast Group ID.
E Currently not being used.

The above table will be clearer after reading the following examples:
Examples:

An IP Address 192.168.1.1 belonging to Class A means that the network ID is 192 and the host ID is 168.1.1

If the Same IP Address belonged to Class B, then the network ID would become 192.168 and the host ID would become 1.1

And if it belonged to Class C then the network ID would become 192.168.1 and the host ID would become 1.
Almost all ISP’s prefer to use a Class B Network. If that is the case then each time you login to your ISP, then the first 2 octets of your IP Address would not change, while the last two are likely to change. However, even if only the last octet changes, and the remaining three remain constant, it is likely that the ISP uses Class B addressing.

How do you find out the IP Address of your own system?

In order to get your own IP Address all you have do is, follow the below process:

1. Connect to the Internet.
2. Launch MSDOS.
3. Type: netstat –n at the prompt.

You will get an output similar to the below:

C:\WINDOWS>netstat -n

Active Connections

Proto Local Address Foreign Address State

TCP 192.168.1.1:1025 64.4.13.56:1863 ESTABLISHED
TCP 192.168.1.1:1031 209.143.242.119:80 ESTABLISHED

The IP Address shown under the Local Address Field denotes the IP address of your system.

An IP Address, which belongs to the Class-A addressing system having a network ID equal to 127, is referred to as the special address. It is actually known as the Loopback Interface. It allows clients and servers on the same system to communicate with each other.

The loopback address, which is commonly used, is 127.0.0.1. Almost all systems have also given the loopback address the special name ‘localhost’.

Now Install Win XP Automatically !!

You can create a CD that can install Windows XP automatically, putting in all the details and answering all the dialog boxes.

The secret behind this is the answer file, which tells Windows what to do while it's installing. The answer file can be created using Windows setup manager.

Using this tool, you can make the answer file so powerful that you can even tell Windows to include or exclude individual components, set the display resolution, and more.

Here's the Steps involved in creating XP Automated Installation Disc :

Step 1:
To begin with, insert your Windows XP installation CD into the drive and copy the entire contents of the CD to a new folder on your hard disk.

Step 2:
Navigate to the Support > Tools folder on the CD and double-click the Deploy.cab file. Copy all the files to a new folder on your hard disk.

Step 3:
The crucial part begins now, creating the answer file. To execute the windows setup manager, double click the Setupmgr.exe file from the contents of the Deploy.cab, which you just copied onto the hard drive.

Step 4:
The first few steps of the wizard are self explanatory. Select the following options from the successive dialog boxes. Create a new answer file; Windows unattended installation (Select the appropriate Windows version); "Fully automated"; "No this answer file will be used to install from CD"; and finally, accept the license agreement.

Step 5:
Under the General Settings, you can customize the installation of Windows by providing the default name and organization, display settings, time zone and the product key. Fill in the fields using the drop-down list or by keying in the details. If you don't select an option from the drop-down list, the default values will be used.

Step 6:
After you are done click Finish and save the answer file as "winnt.sif" when you are prompted. Advanced users can further tweak the answer file by referring to the Help file called Ref.chm in the same folder.

Step 7:
Finally copy the answer file to i386 folder in the Windows XP installation folder you created in the beginning.

Step 8:
To burn a bootable installation disc, you need the boot sector of the Windows XP CD. Download it from here bootfiles.zip

Step 9:
Launch Nero and select CD-ROM (Boot) from the New Compilation dialog box. Under the Boot tab, specify the boot sector file you downloaded and extracted. Set the emulation as "No emulation", and keep the boot message blank. Most importantly, remember to set the "Number of loaded sectors" as 4.

Step 10:
Under the Burn tab, set the write method to disc at-once. Click the New button to to begin adding files and folders to the compilation. Drag all the contents of the Windows XP installation disc that you copied to your hard drive (with the answer file in the i386 folder) into the left pane. Insert a blank CD into the optical drive and hit burn button. Your windows automated installation Disc is ready..!!

Problems of Changing the Boot Screen !!

If you download a hacked system file with a new boot screen and replace the old file on your computer, after you restart, you may find that your computer will not start and will give you a nice error message.
C:\Windows\System32\ntoskrnl.exe is missing or corrupt
Missing or corrupt?
This is the most common problem that users experience when trying to change their boot screen using the file swap technique.
Users that get this message, or any similar error message, are receiving it because they replaced their system file with a file that is not compatible with their version of Windows XP.
Windows XP was released in many different languages for different parts of the world. Each language version of XP has a slightly different version of code. Additionally, Microsoft continuously releases software update patches to update the code of the system files such as the monthly security updates and almost yearly service packs. All of these factors result in several different versions of the boot screen system file floating around on the Web.
You could find a boot screen file that was made from a hacked system file from the German version of Windows XP. Or more commonly, you could find a boot screen that was made from a hacked file from the original version of Windows XP.When you try to install that boot screen on a computer that, for example, has Service Pack 2 installed on the English version of XP, you will have problems.
Windows XP will only work with a specific version of the system file that contains the boot screen.
This arrangement complicates the change of the boot screen with the common file swap technique. It will do so because users will have difficulty telling on what version of Windows XP a particular boot screen that is distributed on the Web will work. Users have to be aware of more than just the version problem. Because you are downloading a hacked version of a critical system file that is executed during the boot sequence, you could possibly download a version that someone modified and in which she /he put some variation of malicious code that could harm your computer..!!
