My office built on this device is office 2016 , If I tick HD I can see other setting of playing videos then blink and change again

       How can I restore the original settings of browsing video, tv , office and cloud storage? I reset my pc recently. the deleted account was my on this device account . My old account activated on this device seems like a third party because my previous device was damaged. I observed that every time I attempt to recover my account notification on my cellphone or I can not open right away.
