Broadly speaking, you can try one or all of these :
Run CCleaner to clear up PC Junk. Reboot. If you are using windowsupdate try using microsoftupdates and vice versa.

If you still cannot Update Windows Vista (orWinXP/SP2) using windowsupdate, try this :

Open Internet Explorer > Tools >Internet Options > Security > Click ‘trusted
sites’ icon >Click Sites > uncheck ‘require server verification’
Then add following sites :



Click Close > Apply > OK. This is known to help the GenuineValidated Windows, in some cases, but not always.

Else, lastly, note your error code and visit this excellent Microsoft Resource : Windows Update Support: Error Codes. Search for the solution against your error Code.

    Richard, you genius.
    I am scared to admit how many hours I have been sitting in front of this wonderful computer screen trying to find a solution to this problem
    Nothing of nay value from Microsoft update would come onto my pc, no updates, no security, no nothing. I used another pc to get essentials going and that had no ipmact. but your method worked a treat. And it did it straight away.
    Well done that man
    Take a medal!
