I have two Windows 10 Pro computers that connect to a Server 2008 Remote Desktop server. They have been connecting sucessfully for a few weeks. Just recently, one PC started displaying a "The hardware ID does not match the one designated on the software license" error when I try to connect via RDP. Then, few days later, the other PC started doing the same thing.
I believe I can solve this by deleting the MSLicensing key on the PC and have it re-created on the next connection. This will take another RDP license from the server, but my original license should be freed up after some period of time.
Why would both PC's start displaying this message? Is it related to a Windows 10 update? Perhaps the Windows 10 Anniversary update?
