I'm using VNC for remote access and test for a small computer with Windows10.
Everything is working fine, expected when i run an application that require the administrator right.
When i run cmd.exe, it's ok. But if i run cmd.exe with administrator rights, the problem appear.
And when i run an exe with the small blue and yellow shield, (regedit, event viewer, visual studio installer, etc.), this is the same problem.
I keep the display (with refreshing), but mouse and keyboard have no effect on the remote computer. And when i close the cmd.exe (or other offending software) with the local mouse, remote mouse and remote keyboard magically work again.
I have tried with different server (TightVNC & TigerVNC) and different clients (Screen Sharing, RealVNC & TigerVNC). My viewer is a running OSX.
No problem with RDP, i keep the control.
I don't think it's a bug, it's too specific and reproducible. Maybe a parameter from Windows 10?
