The operating system above does not have a dedicated Windows Update screen, but it accesses the Microsoft site through a Web browser and performs Windows Update.

How to fix

This section provides step-by-step instructions for the Windows Server 2003 R2 environment. The procedure is almost the same on other operating systems. Windows Update screen is different, but basically, it's fine if you follow the flow on the screen.

The first step is to log in with a user with permissions in the Administrators group.

Open the text editor and save it with the extension ".bat" file by typing the following: The file name doesn't matter.

net stop wuauserv
cd %systemroot%
rd /s /q SoftwareDistributionold
ren SoftwareDistribution SoftwareDistributionold
net start wuauserv
net stop bits
net start bits
net stop cryptsvc
cd %systemroot%\system32
rd /s /q catroot2old
ren catroot2 catroot2old
net start cryptsvc

After saving the file, double-click the file to run it. For Windows Vista, Windows 7, right-click the file and select Run as Administrator.

Wait for the command prompt to close automatically when it opens.

Restart Windows when you are finished. You may not have to restart, but you should be more sure to restart it.

Try running Windows Update when the restart is complete. As shown in the illustration, windows update will prompt you to update itself, so follow the steps (the contents of the screen may vary depending on your environment). You can do Windows Update after you're done.
