Im using Microsoft's remote app installed on Server 2012 R2 and windows 10 client. While moving between the local windows and the remote windows (with ALT-TAB) the alt key gets stuck on the remote window and released only after pressing any random key.
After investigating this problem i found out that it happens only in windows 10 and its related to the client RDP version (10+). In Windows 7 this problem does not appear (RDP 8.0). I also tried to install Server 2016 and this problem this exists.
I'm looking for a solution to this problem, and there is nothing useful on google result.
