"After running a repair, you may find that Windows Update refuses to install the most recent 80 patches. This is because the latest version of Windows Update is broken, and doesn't register some DLLs if they're previously been registered (as happens with a repair install). Here's a work around until they get it fixed:
1. Stop the Automatic Updates service. To do this, follow these steps:
1. Click Start, click Run, type cmd, and then click OK.
2. At the command prompt, type the following commands, and then press ENTER after each command:
net stop wuauserv
exit
2. Register the file that is used by Windows Update and Microsoft Update. To do this, follow these steps:
1. Click Start, click Run, type cmd, and then click OK.
2. At the command prompt, type the following command, press ENTER after the command, and then click OK when you receive a verification message:
regsvr32 %windir%\system32\wups2.dll
Note: for x64 machines regsvr32 %windir%\syswow64\wups2.dll
3. Start the Automatic Updates service. To do this, follow these steps:
1. Click Start, click Run, type cmd, and then click OK.
2. At the command prompt, type the following commands, and then press ENTER after each command:
net start wuauserv
exit
edit: New knowledge base article on this issue, and a post on the Microsoft Update Blog."
