Boot Windows in Safe Mode

Running Windows in safe mode can be helpful when trying to troubleshoot certain problems like removing viruses or spyware. If you are able to detect but not remove a virus or adware, try booting into safe mode and removing it there.
Note: You cannot uninstall programs through the Control Panel in safe mode. This must be done in normal mode.
To boot Windows into safe mode do the following:

Windows 10

From Settings

1. On the Windows sign-in screen, press and hold the Shift key while you select the Power  > Restart.
2. After your PC restarts to the Choose an option screen, select Troubleshoot > Advanced options > Startup Settings > Restart. 
3. After your PC restarts, you'll see a list of options. Select 4 or F4 to start your PC in safe mode. Or if you'll need to use the Internet, select 5 or F5 for Safe Mode with Networking.
