We all know that an administrator has all the privileges to allow or block a specific user account. Broadly speaking, there are two main groups on a Windows machine and they’re Administrator and User group. In case if User group isn’t allowed to sign-in, not even a single user can login. In this condition, when an user try to sign-in, he gets following message:
The sign-in method you’re trying to use isn’t allowed. For more info, contact your network administrator.
Or you may came around this error:
The user has not been granted the requested logon type at this computer.
If you’re the administrator of the machine, and users getting this error message when they try sign-in, you can easily fix this issue for them by granting permissions. The root cause of this problem is that users who are facing this issue is not part of User group. Or one other cause may be that User group don’t have permission to have its members log in locally. These simple steps will help you to fix this problem:

I’m the only user on the machine. I’m at a loss as to how to fix the problem but was already considering a fresh install so I may just do it now. That aside I’m still wondering how to fix this situation in my case.
