Work through the Forum's tutorial here: Windows Update - Reset - Windows 7 Forums

If that doesn't help then use the MS tool and steps here: reset Windows Update components

Try running MS Standalone Service Pack 1 installer normally for developers, but useable in these situations to manually install SP1.

If that fails then what works for me in the past is a Repair Install

Can you let us know exactly which step(s) fixed the problem, so it will help others in the future?

Because of the pithy title the thread will be found for many years in countless Google searches.

When ready you can also mark the thread Solved at top.
