Windows update does not work after upgrading to windows xp pro.

Hello there.
I have recently upgraded 5 machines from windows xp home to windows xp pro. (used upgrade cd and have valid key for all the machines)

That worked great but im unable to run windows update on any of the machines.
It does not come up with any of the known error message. It just says failed to install. With no error code.
There is diffrent hardware on all of the machines.

IE did not work either on the machines. It only allowed one window open at once.
But after i upgraded (downloaded from MS from the server) It started working.

This will happen sometimes after you install one operating system on top of another one . . try this:

Re-register the Windows Update DLL with the commands below

Click Start, click Run, type cmd, and then click OK.
Type ( or copy and paste ) the following commands. Press ENTER after each command.


regsvr32 wuapi.dll
regsvr32 wuaueng.dll
regsvr32 atl.dll
regsvr32 wucltui.dll
regsvr32 wups.dll
regsvr32 wuaueng1.dll
regsvr32 wucltui.dll
regsvr32 wups.dll
regsvr32 wuweb.dll
regsvr32 wups2.dll
regsvr32 msxml.dll
regsvr32 msxml3.dll
regsvr32 msxml2.dll
regsvr32 qmgr.dll
regsvr32 qmgrprxy.dll
