   Is this an update error? You could try this, but back up the registry (create a restore point) first!

   1. Click Start and then type notepad in the Start Search box.

   2. Click Notepad in the Programs list.

   3. Copy the following commands, and then paste them into the opened Notepad window:

   REGSVR32 WUPS2.DLL /S
   REGSVR32 WUPS.DLL /S
   REGSVR32 WUAUENG.DLL /S
   REGSVR32 WUAPI.DLL /S
   REGSVR32 WUCLTUX.DLL /S
   REGSVR32 WUWEBV.DLL /S
   REGSVR32 JSCRIPT.DLL /S
   REGSVR32 MSXML3.DLL /S
   ——————————————————————————————————-
   1. In Notepad, on the File menu, click Save As.

   2. In the Save as type list, click All Files.

   3. In the File name box, type register.bat.

   4. Save the Register.bat file to your desktop.

   5. Right-click the Register.bat file, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password or click Continue.

   * The solution, in a nutshell, is to disable your firewall. If you’re using McAfee Personal Firewall Plus, F-Secure Internet Security, Norton Internet Security or another Firewall vendor, see its respective support page for assistance in disabling it (temporarily). If you’re using the built-in Vista Firewall, keep reading.

   * Open the Control Panel and select Security.

   * Select Turn Windows Firewall on or off.

   * Select Off (not recommended), click Apply and then OK.

   * Back at the Windows Update screen, click the Try again button.

   * The download(s) and installation should start…

   * and this time successfully install. If a restart is required, make sure to re-enable your Firewall once your PC restarts.

   * Though this solution will work for most Vista Update errors

   Hope this helps, XD.

   If you are referring to windows update error 646 then simple solution is right click on update and then click hide. This happens when you recieve a update that is not needed.
