Safe mode is a diagnostic mode used by computer operating systems to troubleshoot problems that cannot be fixed while running in normal mode. In safe mode, the operating system loads only the necessary (minimal) drivers and software so that other problems can be found and repaired.
Safe mode is designed to help you find problems with your apps and widgets, but it disables parts of your phone. Pressing or holding certain buttons during start-up will bring up recovery mode.
If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to start in safe mode, and then press F8.

When should safe mode be used?
Safe mode is a boot option in which the operating system starts in diagnostic mode rather than in normal operating mode. It is used primarily for troubleshooting a system that has crashed, failed to boot correctly or is experiencing instability after installing an update, device driver or new software installation.
Safe mode allows you to boot up your OS in a very basic state so you can potentially identify and fix the problem. While in safe mode, your screen resolution may look a bit off, certain applications might not work properly, or your computer may run a bit slower than usual.
Type the command for the type of Safe Mode you want to use, and then press Enter. This will force the computer to reboot into that version of safe mode immediately after rebooting. Safe Mode: bcdedit /set {current} safeboot minimal. Safe Mode with Networking: bcdedit /set {current} safeboot network.
