If I enter a command for each user created to run from runonce what I should do? If I use wim registry editor and load "users\default\ntuser.dat" and add my command to: HKEY_LOCAL_MACHINE\WIM_Default\Software\Microsoft\Windows\CurrentVersion\RunOnce Will it run every time a user is created? I Know that I could test but I'm in hurry to reinstall windows 7 in 3 Pc home network before my trip there ends.... And I'm not that familiar with 7. That is something I would have done in the same case for XP. Also I cannot figure how does the changes been saved? If I close registry editor and save the image will these just be saved?
