Can you make CCleaner clean the windows update list? I usually delete the whole softwaredistribution folder (windows/softwaredistribution) and activate windows update again but it would be easier if Ccleaner could do it. To save more harddisc space. Who uninstalls updates anyway.
People who have problems with the updates
People have been asking for this for a while, but I'm not sure it'll ever be added.
Here's a winapp2.ini entry for it
[Windows Update List*]
LangSecRef=3025
DetectFile=%WinDir%\SoftwareDistribution
Default=False
FileKey1=%WinDir%\SoftwareDistribution|*.*|RECURSE
