After connecting to a remote session via RDP, windows keyboard shortcuts appear to be sent to both the local machine and to the remote machine.
As an example, pressing the Windows key opens up the start menu on both the local and the remote machines. Pressing a combination such as Win+R (on the remote desktop) opens up the Run dialogue box on the local desktop.
Within the Remote Desktop Connection (mstsc) settings, the Windows key combinations are set to, "Only when using the full screen" (keyboardhook:i:2). The RDP session is full screen and Ctrl+Alt+Pause/Break properly changes between full screen and windowed modes.
I have read about people having (possibly) related issues with locking their machines via Win+L while a remote client is currently focused. I have followed their various fixes to no avail.
Any ideas or pointers are greatly appreciated.
