the shift alt and ctrl keys have stopped working in conjunction with the numerals and grammar/mathematics keys. i've tried all the usual fixes, all the shortcuts, restoring the pc to an earlier point, bios defaults etc etc - none of it worked
To answer your question, I haven't installed any new software on that particular device. And on principle (privacy breaches / general disempowerment) I haven't updated to Windows 10, although most existing Windows 7 updates are intact. (Most because some wouldn't reload after my failed attempt to restore to an earlier point).
Last time that device worked fine was approx three weeks ago - there was a long interlude when I couldn't use it for other reasons.
