One of the neatest features that comes with Windows 8 is the ability to revert back to a clean or pristine state. This will help users who accidently messed up their computer by installing crapware onto their machine. This process also allows you to keep your files as well. Like almost everything in Windows 8 it is very easy to do, you just need to know that it’s there.
Make sure you are on the main Start screen (Metro screen). Open the charms sidebar. Using a mouse you do this by hovering over the top right hand side of the screen. Click on the “settings” cog.
At the bottom of the settings bar click on “Change PC Settings”
The screen will morph into the PC settings. Make sure you select “General” on the left side.
On the right side find the section “Refresh your PC without affecting your files” and click “Get Started”.
I hope this helps you revert Windows 8 back to a clean state and keep your files!
