Thanks, I needed that hint. I got my results with the command line: reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce" /v 2 /t REG_SZ /d "\"X:CCleaner\CCleaner.exe\" /auto" /f A seperat regfile is not needed. Lexem

CCleaner has only two sorts of automation 1. the /auto parameter to scan during a windows session and 2. the option to scan on EVERY start of windows. First wish: An option or parameter to make CCleaner scan and clean ONLY on next windows start would be nice. Second wish: A log entry in the event viewer so CCleaner can work with eventtriggers.exe Both wishes make CCleaner behave more like chkdsk.exe Thanks for this programm. Lexem
