On occasion I run into a computer that cannot install the Windows updates.  To resolve this I have a little batch file I run that clears up the issue.  If you want to skip the batch file you can also just cut and past the commands into the command prompt and it will run through each command.

Thanks to Andrew for showing this to me.
