Around about the same time, my X key and my Windows hotkeys stopped working on my keyboard. I've tried reboot. Tried Safe Mode. Looked at a lot of settings. On Dell Inspiron 17, Windows 10.
Any ideas?
@Bull had a similar thing with shift w on another keyboard. turned out a function key was stuck. losing it solved everything. maybe you have some such key somewhere?
@nicolai thanks. I'll check. I might take the whole thing apart and give it a good clean.
