02. When you see the Press any key to boot from CD message, press the space bar, or similar key.

03. Press R on the Welcome to Setup screen to start the Recovery Console.

04. When prompted, type the number of the failing installation you want to access and press Enter.

05. When prompted, type the Administrator password and press Enter.

06. In the Recovery Console command window, type the following commands, pressing Enter after each line:

cd $NtServicePackUninstall$\Spuninst
batch spuninst.txt

07. Remove the Windows XP CD-ROM and restart your computer.

NOTE: See Windows Explorer may not start after removing Service Pack 2 from Windows XP?

08. Open a CMD.EXE window.

09. Type the following commands, pressing Enter after each line:

10. Follow the on-screen instructions to remove Service Pack 2 from Windows XP.
