F8 Not Working In Windows 10? 5 Things To Try
If you’ve upgraded to Windows 10 from older versions like Windows XP, Vista and Windows 7, you may have noticed that the F8 function key you pressed during startup to enter Safe Mode 不再有效。
The F8 key is still available on your keyboard, but it works with other key combinations to perform certain functions, especially when your touchpad or mouse isn’t working and you need to 使用鍵盤快捷鍵 代替。
In this guide, we’re going to show you what to do when you find F8 not working in Windows 10, but first, let’s look at why this happens.
Why Is F8 Not Working In Windows 10?
安全模式 is a native Windows feature in all versions of the operating system, which is used to troubleshoot various problems such as driver installation issues, problems booting into Windows, and malware or virus-related issues among others.
The F8 boot menu was removed in order to improve system boot time. This is because Windows 10 boots much faster than previous versions, so you won’t have enough time to press the F8 key and enter Safe Mode during startup. Plus, it can’t recognize the key press during the boot process, which prevents access to the boot options screen from where you can select the Safe Mode option.
Instead, Microsoft provided a new Advanced Boot Options menu feature that lets you access troubleshooting options such as Safe Mode and others.
You can still access the Safe Mode feature by pressing the F8 key, but you have to re-enable it manually using a few simple steps, and there are other methods that can also get you into Safe Mode, but they’re not as straightforward.
