Some tips on reclaiming the disk space on windows

Watch this space. Some tips on how to free up some space on your hard drive if you had fairly recent Windows OS installed (Vista, Windows 7, Windows Server 2008, etc)

%WINDIR%\SoftwareDistribution\Download - delete whatever is older than 10 days there. Later files may still be needed by ongoing Windows Update

%WINDIR%\Installer\$PatchCache$ - mostly safe to delete.

DO NOT however delete whatever is in the root of %WINDIR%\Installer !!

download msizap utility which comes in Windows Installer SDK - - and run it with g option, i.e. msizap g - it will delete orphaned windows installer files. Other options of this utility may be risky - general rule is that messing with windows installer files that are in your windows folder may break your system and you will need to reinstall it.
