In Windows operating systems, there are different safe mode options available on the "Advanced Boot Options" screen that allows users to either boot into safe mode with command prompt or with networking.

Safe mode is typically used as a troubleshooting option because it starts Windows with only core services and drivers. Windows operation is limited to basic functions in safe mode. If there are programs and drivers that are preventing Windows from starting properly, the basic device drivers and default settings can be eliminated as probable causes by going into safe mode. If a recently installed driver, device or program is preventing Windows from functioning properly, the program can be removed in safe mode.
