That's what it looks like when I right click on the desktop. I also can't copy/paste between applications and lots of stuff is unresponsive e.g. buttons in some applications. I can't even install anything because the buttons are unresponsive.
It all started after the most recent Windows upgrade. I uninstalled the update and that seemed to fix a few applications but all the above is still broken.
I remember something similar happening before (on Windows 8) but I can't for the life of me remember how I fixed it and googling this sort of thing is impossible.
Any advice will be immensely appreciated!
