Windows Update fix

Sometimes Windows Update gets corrupted. Some of its components or previously downloaded updates get mangled during the download or installation process. Here's a quick fix to clean out the folders that it uses (put the script in a batch file):

@echo off

NET STOP "Automatic Updates"

SET D=%windir%\SoftwareDistribution\DownloadDEL /q %D%
FOR /F %%f IN ('dir %D% /b /A:D') DO RD /s /q %D%%%f

SET D=%windir%\SoftwareDistribution\DataStoreDEL /q %D%
FOR /F %%f IN ('dir %D% /b /A:D') DO RD /s /q %D%%%f

SET D=%windir%\system32\CatRoot2DEL /q %D%
FOR /F %%f IN ('dir %D% /b /A:D') DO RD /s /q %D%%%f

NET START "Automatic Updates"

On execution, it wil re-download the main components and give you a "fresh" Windows Update installation.
