Log in as administrator in Windows 8

The real administrator account is hidden intentionally and should not be used for developing – it should be used for maintenance purposes that require full elevated rights in Windows 8.

Basically activating the hidden admin accounts works exactly like it did in Windows 7.

If you’re still having problems performing an administrative task, you should run sfc.exe or check that something else is not blocking the access (firewalls, other processes, etc.)
