The System Readiness Tool is Microsoft's answer for all Windows update issues.
It will check to make sure Windows Updates works, and automatically downloads and fixes Windows Updates issues.
Due to the nature of Windows Updates, the tool will seem to hang for extended periods of time, so it is advised to leave it running and check back every half hour.
