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 :

http://*.windowsupdate.microsoft.com

http://*.windowsupdate.com.

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.

    ============================================================

    a. Start Internet Explorer.

    b. On the Tools menu, click Internet Options.

    c. Click the Connections tab, and then click LAN Settings.

    d. Click to select the Automatically detect settings check box, and then click OK two times

    Step 2: Check whether the IPv4 and IPV6 settings are set to automatic.

    ==========================================================================

    Click on Start, Network.

    Click on Network and Sharing Center.

    Click on Manage Network Settigns from the left.

    Right click on Local Area Connection and select properties from the left.

    Click on TCP/IP v4 properties and then click on Properties, select the option Obtain IP address and DNS settings

    automatic

    Click on TCP/IP v6 properties and then click on Properties, select the option Obtain IP address and DNS settings

    automatic

    Click on Apply and OK to continue

    Step 3: Reflush the IP address and DNS server settings.

    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!
