    • go to a Command (cmd) prompt (Start, Run, cmd, OK)
    • type in, without quotes: "sc stop wuauserv" (or, "net stop wuauserv")
  • in Windows Explorer delete all files from the following folder: c:windowsSoftwareDistributionDownload
    • to get there, just copy and paste that path, above, into your Start, Run line and click OK or hit Enter
    • highlight all the files in there (press Ctrl-A) and either right-click and choose Delete or just press the Delete key on your keyboard. Don’t delete that folder itself, just all files and folders within it
  • turn the Windows Update service back on
    • go to a Command (cmd) prompt (Start, Run, cmd, OK)
    • type in, without quotes: "sc start wuauserv" (or, "net start wuauserv")

Microsoft updates do not install


You have not said which OS you are using so; from http://support.microsoft.com/kb/943144

When you try to install Windows updates from the Windows Update Web site, the Microsoft Update Web site, or by using Automatic Update, you receive a message that the update is not installed successfully. Additionally, the update is not displayed in the update history.

You may experience this issue in the following scenarios:

You visit the Windows Update Web site, or the Microsoft Update Web site.
Note When you visit the update Web site, the latest version of Windows Update software will be installed in your computer.
You install Windows XP Service Pack (SP3) without a restart.
You try to install Windows updates after the install of Windows XP SP3.

Then cause ;

This issue occurs because the Wups2.dll file that is included in the latest version of Windows Update is not installed correctly.

For scenario 1, the registry entries that correspond to the Wups2.dll file are missing after the repair install of Windows XP. The release version of Windows XP does not contain the Windows Update software.

For scenario 2, the registry entries that correspond to Windows Update are changed back to the Windows XP SP2 version if you did not restart the computer before you install Windows XP SP3. The registry entries for the Wups2.dll file are changed to pointing to the Wups.dll file that is included in the release version of Windows XP SP2.
To resolve this problem, use one of the following methods;

Method 1: Download and install the Windows Update Agent,

For an x64-based computer http://download.windowsupdate.com/WindowsUpdate/redist/standalone/7.4.7600.226/WindowsUpdateAgent30-x64.exe

Method 2: Register the Wups2.dll file,
