Windows 10: Hacked?

I think I may have been hacked. Should I back up my personal files and wipe everything off? If so, how do I do that?

77000 Steam accounts hacked every month

Ironically I've had the same crappy password since I made my Steam when HL2 came out and never been hacked, but I've had my Origin account jacked twice with a much more complicated password. 2 step on Origin fixed this problem, but just thought it was kind of funny. I went with 2 step on Steam to be safe too.

 

Hacked.

Have you gone to http://account.live.com and edited your security information via a PC?

Also, look at this link to see the steps to follow:

If your account has been compromised (hacked) it means that someone stole your password and might be using your account to access your personal information or send junk email.

Microsoft Account was hacked

Thank you but they did not change my password and I think I know who hacked into my account. My two step verification was not turned off. I even had to use the two step process a week or so before he hacked my account. He has top secret security clearance
and it seems is allowed to do anything. I just need to tell someone about this I guess.
