@XPerceniol , hi , I'm sorry for the delayed reply , I had busy days . It's the simpliest way , as far as I know . Other tools suggested here didn't work for me at all . I'm not saying they are bad . They just didn't work for me , maybe because I do not use updates , I dunno. Is the second part for me too ? I don't remember you asked me , maybe I missed something . BTW , tried playing with time-travel again , all is fine , I do not have any SHA-2 updates installed at all , but I'm on Vista , so it can be different from XP , though my Vista is actually older than XP SP3. If Dave will count the last sentence as OT , please delete.
