What does the F8 key do in Windows operating systems?

The F8 key, when pressed during the boot process, allows access to the advanced boot options menu in Windows. This menu provides various troubleshooting and startup options, such as safe mode, last known good configuration, and system restore. It is a valuable tool for diagnosing and resolving issues that may prevent the system from starting normally.

How can I use the F8 key to access safe mode in Windows?

To access safe mode using the F8 key, simply restart your Windows computer and start tapping the F8 key before the Windows logo appears. This action will prompt the advanced boot options menu, where you can choose the "safe mode" option.

Why is the F8 key sometimes unresponsive during startup?

Some modern Windows versions have fast boot options enabled by default, which may cause the F8 key to be unresponsive during startup. To access the advanced boot options menu in such cases, hold down the shift key while clicking on the "restart" option from the start menu.

Where can I use the F8 key outside of Windows?
