I am using Windows Vista Home Premium 32-bit with CCleaner v2.06.567 and have a few additional features for the program to clean: WINDOWS ERROR REPORTING FileKey1=%allusersprofile% Microsoft Windows WER ReportArchive *.* RECURSE FileKey2=%allusersprofile% Microsoft Windows WER ReportQueue *. Homeworld 2 Macross Mod. * RECURSE FileKey3=%localappdata% Microsoft Windows WER ReportArchive *.* RECURSE FileKey4=%localappdata% Microsoft Windows WER ReportQueue *.* RECURSE The Disk Cleanup utility built into Vista cleans these files but is very slow at doing so. PERFORMANCE AND RELIABILITY MONITOR FileKey1=%programdata% Microsoft RAC PublishedData *.* FileKey2=%programdata% Microsoft RAC StateData *.* Upon deleting these report logs, Windows Vista may take around 24 hours to generate new reports again.
