If you don't, the spyware can interfere with the install and wreck the system. I bet a lot of people having trouble with SP2 are being hit by problems like this which are not SP2's fault.

After you install Microsoft Windows XP Service Pack 2 (SP2), your computer repeatedly restarts with the following Stop error:
A problem has been detected and Windows has been shut down to prevent damage to your computer...
Technical information:
STOP: c0000135 {Unable To Locate Component}
This application has failed to start because winsrv was not found. Re-installing the application may fix this problem.
Note Your computer may restart immediately if it is configured to automatically restart when a system failure occurs. To turn off this option so that your computer does not restart, press F8 at startup, use the arrow keys to select the Disable automatic restart on system failure option, and then press ENTER.
This problem may occur if all the following conditions are true:
- T.V. Media (TvMedia.tvmbho) from Total Velocity Corporation is installed on your computer.
- You have not installed Critical Update 885523.
- You tried to install Windows XP SP2.
A compatibility issue between the Windows XP SP2 installer and a third-party advertising program that is named T.V. Media can cause this problem. The problem occurs when you have T.V. Media installed on your computer, and you try to install Windows XP SP2. You receive a Stop error when you restart your computer, and the installation process fails. You can prevent this problem by removing T.V. Media or by installing Critical Update 885523 before you install Windows XP SP2.
