The F8 key is a function key found on most computer keyboards, typically used to access special features or commands. On Windows systems, it is often used to enter the boot menu or Safe Mode during startup. Understanding the F8 key’s functions can enhance your computing efficiency and troubleshooting skills.
What Are the Common Uses of the F8 Key?

- Windows Safe Mode: Pressing the F8 key during the boot process allows users to access Windows Safe Mode, a diagnostic mode for troubleshooting issues.
