Have you installed Service Pack 3 for XP only to have registry corruption render your PC inoperable? Symantec finally released the tool that cleans up the registry corruption that occurs when a user attempts to install SP3 while SymProtect, Symantec's hacking protection module, is active. You can grab it here.
Symantec has also issued a patch via its LiveUpdate service that prevents the registry corruption from occurring, although users must run LiveUpdate from within their security software, then reboot the PC before attempting an upgrade to Windows XP SP3 or Vista SP1.
