XP Home SP2 update hangs half way through
Like many XP users, I had tremendous problems while trying to install SP2 on
my computer. Searching the internet, message boards, and Microsoft Support
were some help, but not enough. Here are the results of my experience.
This text assumes a basic knowledge of how to use regedit.
The reason why SP2 would not install was because several registry keys were
out of wack. First, I searched my registry and deleted all registry keys and
values with "vnd.ms.radio". For one of them, I had to change the permissions

Spysweeper from WebRoot was installed on this computer. However, I thought
that it might intefer with the SP2 update. So, I deselected the Program

believed that Spysweeper was disabled at this point. However, THIS IS NOT
CORRECT ! Looking in Task Manager, I saw that "Spysweeper.exe" was still
At this point, I uninstalled Spysweeper and rebooted the computer again.
This time, spysweeper.exe was not listed in task manager. Using "regedit", I
naviated to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\SSDPSRV.
Then added "New>Multi-String Value" "DependOnService". Once added, I set the
value to "HTTP".
Once this registry key was added, SP2 installed with no problems. Then
Spysweeper was reinstalled.
