We decided on not having the custom screen capture feature anymore, since Windows now has a snipping tool which can be used for that effect. Can you please remove it?
How can we disable a shortcut with the current UI?

I think we should also set new defaults to shortcuts that won't conflict with Ctrl+Alt+Letter.
I guess Ctrl+Alt+Win+Letter would be good but first please check if that won't conflict with other shortcuts for the letters we currently have associated.

Giving it a test, Press Ctrl three times is upgrading into VK1? It should be disabled, I think.

I've tried the new default Windows+Control+Alt+L to lock all machines and it seems to not be working. Works when I set it to a different combination, though.
Can you please check if the new defaults work out of the box?
When I press Windows+Ctrl+Alt+L it sends the pointer to the center of the screen, which is weird?
