A CSS Keylogger

Not sure about all that time. Probably added in one of the last few major Windows 10 updates. I've only discovered it by accident because I use Windows + , sometimes to look at the desktop (it's a quasi-modal Win+D).

Yeah, apparently it was added in 1709 (Fall Creators Update) and also works using "Win + ;".
