I upgraded Windows 7 Pro (legit license) to Windows 10 Pro. My main computer uses Windows 8.1 (WTK activated). When connecting to another Windows 8.1 computer using remote desktop the connection goes through smoothly and I take control of the computer. When I connect to the Windows 10 Pro computer my connection is dropped with this error. It seems that the Windows 10 computer drops the connection and logs back in with the default user. Is there any way to correct this? I'm about to dump Windows 10 and go back to 8.1 because of this. Thanks.
