All of a sudden, some keyboard shortcuts seem to have stopped working in applications. The two I'm noticing it for are Ctrl+K and Ctrl+W. This is happening across multiple applications which should support those hotkeys.

I've tried running Spy++ to monitor the Windows messages, and it looks as if when Ctrl is pressed, no keyboard events are being sent for the K key press. However, pressing K without Ctrl does work.

This seems to be happening for the W and K keys, and also Arrow right.

I've tried using Windows Hotkey Explorer, but there's nothing obvious registered in there.

Any ideas to what could have caused this?

I ended up reinstalling the keyboard drivers and this fixed it.

(edit) Turns out that rebooting after installing the drivers has brought back the issue!
