I know that is is highly recommended that we install windows xp update service pack 2. I tried this on our computer, and after it was installed, I kept getting a blue window saying an error message and was unable to access my normal windows desktop. This kept happening until finally I uninstalled the service pack in safemode. After that, I was able to access Windows as usual. I don't understand why this happened and what I should do since the only thing that changed was installing the service pack!
Any help is greatly appreciated. Thanks!
