Windows has made the process of resetting your system a lot easier since Windows 8 in the event when things went really wrong. When resetting/refreshing seems to be the only choice to go to make your Windows run properly, you can simply go to Settings app → Update and recovery, and do either of the process from there.
But that works only when you still have access to your desktop. What if things really went south and you have no access to your desktop or simply can’t get Settings app to work properly?
Here is a quick trick that lets you boot to the Advanced boot option right from login screen.
When you are on Login screen, click the Power button, hold down Shift key and click Restart option.
And keep holding down the Shift key until the following screen appears.
Now click on Troubleshoot, and Reset this PC to start Reset process.
The Reset process has 2 options in Windows 10, either Keep my files which is similar to Refresh as in Windows 8.1 or Remove everything like start from the scratch. Pick one that suits you to start.
Ant that’s about it.
