Hi, I think I found the real name in english for "Tâches planifiées" . I saw in Windows XP pro that you need the administrator password to make a scheduled task works. But the point is that I didn't put any admin password because when I start the computer I want it to load until the desktop. I don't want to write a password. When I tried to make a new scheduled task, it never worked. I saw that the Norton Anti-Virus scan was working. So i tried to copy paste this schedule and the copied file just didn't work. There's something special in the original Norton Anti-virus scan that makes the scheduled task work without any admin password. When I try to put a password in the scheduled task, it says that's not the good password. When there's no password it says it doesn't work because no password has been written. I wonder how the NAV works, if someone can help me, that would help me because I want the NAV and The Cleaner have a scan each week. Thanks !
