Description
Safe mode is a special diagnostic mode to that helps you isolate the problem when Windows doesn’t start properly, allowing you to then use one of a variety of disaster recovery tools.
As safe mode is a Windows environment that only incorporates a small number of necessary functions, so some of your computer equipment might not be available in Safe Mode.
Additionally, the screen resolution is set low and the number of colors available is also limited.

Note that in Windows 10, because you are using a high-speed start when you press the F8 key on the keyboard during start-up, there will be no prompt about selecting Windows 7 or an earlier OS.
