Files required to use Microsoft Update are no longer registered or installed on your computer

ComTech: IT Support Scotland


Came across this little baby last week when trying to update a Windows XP laptop after a reinstall.  Turns out that although there were no errors during installation some of the dll files used by Windows update were not registered.  This is how to fix it.

Click on Start – Run and then type the following.  Remember to press return after each one.

regsvr32 wuapi.dll

regsvr32 wups.dll

regsvr32 wuaueng.dll

regsvr32 wucltui.dll

regsvr32 atl.dll

regsvr32 msxml3.dll

Once completed restart your computer and Windows Update should work as normal.  In my case it turns out I was actually missing the last file which I had to download first and then register it.
