just to let anyone know I installed Service Pack 3 for Xp pro and it won't let me install ANY updates!!!!
So i looked around on the update fourms and found this:
Open Start, Run, and run these commands, one by one:
regsvr32 /s wuapi.dll
regsvr32 /s wuaueng1.dll
regsvr32 /s wuaueng.dll
regsvr32 /s wucltui.dll
regsvr32 /s wups2.dll
regsvr32 /s wups.dll
regsvr32 /s wuweb.dll
Next time you open Windows/Microsoft Update, you should have no problems
installing new updates.
it works just to give ya all an heads up ok
