Ctrl+Alt+Left Arrow and
are eaten up by the Remote Desktop Client.
Their only effect is to switch you to back to the host computer.
It looks like this was some intended feature that was never fully programmed
and completed, but there is no way to turn it off.
These hotkeys are not even listed by Microsoft in its official documentation at
Remote Desktop Services Shortcut Keys.
Solution 1 : Use the Microsoft Store version
Another version of RDP can be found in the Microsoft Store at
Microsoft Remote Desktop.
This version does not have this semi-implemented feature, so it lets through
these hotkeys without a problem.
This was verified on Windows 10 version 1903.
Solution 2 : Translate the hotkeys on both client and server
This solution will use AutoHotkey
installed on both client and server, to:
- On the client, translate the above hotkeys to others that are not intercepted
- On the server, translate these keys back to the above hotkeys.
You may for example use on the client the following AutoHotkey script to convert
;Send Ctrl+Win+Left when user types Ctrl+Alt+Left
;Send Ctrl+Win+Right when user types Ctrl+Alt+Right
You may use on the server the following AutoHotkey script to convert
;Send Ctrl+Alt+Left when user types Ctrl+Win+Left
;Send Ctrl+Alt+Right when user types Ctrl+Win+Right
If required, you may restrict these hotkeys to particular windows or process
by using the AutoHotkey commands of
#IfWin[Not]Active / #IfWin[Not]Exist.
