Since few days ago I'm encountering a weird bug.. or new feature? When I press Ctrl-Alt key the shortcut key leads Ctrl-Alt-Del combo keys. So when I press Ctrl-Alt the screen turned to the blue screen. I've been working on Windows 10 for longs years. This is first time I got this bug. I searched Twitter and google but it seemed anyone had not this bug. I also checked some software installed, working on background. but I didn't install any suspicious software recently and the background items also seemed ok. I turned some items off and checked whether the problem solved or not. The autohotkey scripts were most suspicious ones but even after turned off the ones the problem still went on.
Is this bug not new feature, right? If this is bug, what can I do to try to fix this problem? thanks.
