The XP service center is part of the files and applications associated with the various Windows XP Service Pack installation program. Microsoft developed three service packs for updating the Windows XP operating system.
Uninstall Updates
One method for uninstalling the Windows XP Service Pack involves typing "appwiz.cpl" into the Search box on the Start menu. This will bring up a series of prompts that allows the user to view installed updates and select the appropriate ones to be uninstalled.
System Restore
Another method for uninstalling the Windows XP Service Pack is to access the System Restore menu by typing "rstrui" in the Search box on the Start menu. This will open the Restore System Files and Settings windows. Users can use this menu to choose a Restore Point that is prior to the installation of the XP Service Pack and roll the system back to that point.
Hidden Service Pack Uninstall Folder
When installed on a computer running Windows XP, the XP Service Pack creates a hidden uninstall folder. Users access the hidden uninstall file by opening the Start menu and clicking on "Run." When the Run menu opens, the phrase "c:\windows\$NtServicePackUninstall$\spuninst\spuninst.exe" can be entered to bring up the Service Pack uninstall wizard.
