I have searched for this on the internet and you have to scroll through 25 lines of text to get to the answer so I am writing a quick guide. I needed to do this to run CHKDSK on my drive.
The Visual Way:
Go to the Windows Apps screen by clicking the down arrow on lower left corner on the Start screen then scroll or swipe to the Windows System heading and you will see the command prompt app.
Right click on the app and you will get a dialog box that gives you the option to Run as Administrator. Click that option and you will get an elevated command prompt to run administrator level commands like CHKDSK
