The troubleshooter didn't work. What do i do now ? I also formatted it recently. Dont know which one is the cause.
Did you have this license linked to an MS account? (I dont know)
What "OEM" is this? (Windows 10 Pro)
What specific error did you get? (It says that it couldn't be activated)
Did you contact Microsoft?(Tried to but coudln't)
