SAFE MODE on WINDOWS-10 Using F8 Key

Safe Mode is a way to run Windows in its most basic form. It uses only absolutely essential files and drivers. For example, in Safe Mode

your screen will display only 16 colors
and a very low resolution
and you won’t be able to print documents or hear audio
It also won’t load many programs in the background

Safe Mode is designed to help you troubleshoot computer problems

Sometimes Windows will automatically start in Safe Mode (e.g. if it has a problem loading normally).

But sometimes you’ll need to start it in Safe Mode manually (e.g. if you get a blue screen error every time you start Windows)

This article explains how to manually start Windows 10 in safe mode by pressing F8 at startup

This method must be manually enabled from within Windows. If you haven't already enabled it, and you can't access Windows to do so, skip to below.

First, you have to enable the F8 key method

On Windows 7, you could press the F8 key as your computer was booting to access the Advanced Boot Options menu. From there, you could access Safe Mode. But on Windows 10, the F8 key method doesn’t work by default. You have to manually enable it.

Here’s how to get the F8 key to start Safe Mode in Windows10

1) Click the Windows start menu and type cmd, then click Run as administrator

2) Copy this command:

bcdedit /set {default} bootmenupolicy legacy

3) Paste the copied command into the Command Prompt (right-click in the Command Prompt to paste), then press the Enter key on your keyboard.

4) Reboot your PC.

Now that you’ve enabled the F8 method, you can use it to start Safe Mode:

Ensure your computer is turned off.
Turn your computer on.
Before anything appears on your screen, press F8 repeatedly until the Boot Options menu below displays.
Then select Safe Mode.
