To uninstall Windows XP

Under rare circumstances, you may need to uninstall Windows XP and return to your original operating system.

1.

Open Add or Remove Programs in Control Panel.

2.

In the list of programs, click Windows XP, and then click Change/Remove.

3.

Click Uninstall Windows XP, and then click Continue.

4.

If any programs have been modified since the upgrade to Windows XP, you will receive a warning message. Review the warning, and then, if you want to continue with the uninstall process, click Continue.

5.

Click Yes to confirm that you want to start uninstalling Windows XP.

Your computer will restart automatically. Be sure that any floppy disks are removed before you click Yes.

 Important

You can not uninstall Windows XP Professional if you:

Changed your hard disk configuration; for example, if you have converted from FAT to NTFS or have created new partitions.

Upgraded from Windows NT 4.0 or Windows 2000 Professional.

Programs that have been modified since the upgrade to Windows XP will not be consistent after the uninstallation. For example:

If you remove a program and then uninstall Windows XP, parts of the program (such as Start menu links) will be restored by the uninstallation process, but other parts of the program (such as its program files) will not be restored.

If you add a program and then uninstall Windows XP, parts of the program (such as its registry settings) will be lost.

Changes to programs can result in error messages after the uninstallation process is complete.

Note

To open Add or Remove Programs, click Start, click Control Panel, and then click Add or Remove Programs

Windows XP will warn you of any issues before the uninstallation process begins. To correct the problems, repeat changes after Windows XP has been uninstalled.

New files added to the computer while running Windows XP will not be deleted. This includes files such as spreadsheets, e-mail messages, desktop shortcuts, program files, and so on. Some of the files might be created as you use programs, such as word processing documents.

If you installed a newer version of a software program while running Windows XP, some of your documents might not be accessible because the version of that software program installed on your previous operating system might be older. For example, suppose you use a program to manage your finances. If you upgraded to a newer version of the finance program on Windows XP, you document files might have been converted to a newer file format. After uninstalling Windows XP, you will need to install the updated version of the finance program before you will be able to access your documents.
