Adding Safe Mode Support (Windows Embedded Standard 2009)
You can add the Safe Mode Support component to allow users to boot in safe mode. When they boot the device and press F8, they will get three Safe Mode options:
Safe Mode (standard).
Safe Mode With Networking. This includes additional network-related drivers and services
Safe Mode With Command Prompt. This runs the command prompt application (Cmd.exe) as the shell instead of running Windows Explorer.
When they choose one of these modes, Windows loads only the drivers and services that are necessary for the computer to boot.
