Q. Is there an RDP 10 update for Windows 8.1?

A. Windows Server 2016 and Windows 10 introduces support for RDP 10 while Windows 8.1 supports RDP 8.1 only. When Windows Server 2012 was released there was an update for Windows 7 to bring support for the latest RDP 8 capabilities. This will not happen for Windows 8.1. For the latest RDP capabilities you need to use Windows 10.
