Hi everyone,

I had upgraded to Windows from windows 8.1 to windows 10. When I was on windows 8.1, I enabled built-in Administrator account and that is the only user which has the admin privileges.
But after upgrading to windows 10 that built in Administrator is disabled and none of the users are having admin privileges. Now what is the way to get admin privileges on one of the users or get the built-in Admin user enabled?

Thanks in advance.
