After you’ve repaired a Windows XP (SP2) installation using recovery media, any update from Windows Update or Microsoft Update refuses to install. You’ll end up downloading 50+ updates that simply won’t install.
Re-register the Windows Update services.
- Open Notepad
- Copy and Paste in the following (as is):
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
- Save as "fixp.cmd" (set Save as type to All files) to somewhere convenient
- Run the file
- Head over to Windows Update to install your downloaded updates
This worked for me. If it doesn’t help your problem might be a virus or your anti-virus application(s). Try updating in Safe Mode. Thanks to Windowssecrets.com.
