I create batch who install a lot of program But the server need to reboot himself. I want to server that reboot without login screen.

you will always get the login screen, you can't bypass that. However you can set yourself up an administrator account with no password!! i think there is a key to put in the registry, so you don't have to press Alt-Ctrl-Del, but i don't know what it is

Set the following keys using reg.exe in your install batfile followed by shutdown if your install doesn't include it. [HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon] AutoAdminLogon=1 DefaultUserName="username to use" LegalNoticeCaption="must be blank" LegalNoticeText="must be blank" DontDisplayLastUsername=0 [HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce] "name of batfile to reset reg keys and reboot or logoff"="path to batfile\filename" make sure you reset the winlogon regkeys and include either reboot or logoff. I have just used this method to deploy Internet Explorer and it worked fine.
