Start menu popping up all the time

I have been thinking the same. BUT: When you reformat the disk and reinstall Windows from scratch, I'd think that you get a new and fresh keyboard driver with the OS reinstallation. I also suspect a connector/chip/circuit issue. That is why I had my friend open Notepad and start typing - I'd think that this kind of noise would appear in Notepad just as much as in the desktop input. But none such was observed. I did tell my friend to grab the PC by its neck and shake it while telling it in a stern voice to start behaving. Of course this was said as a joke, but if there is a bad connection somewhere, a little shaking could both break the connection permanently, or cause it to settle down with better contact. I might try to give it a (not too violent) shake when I get there, to see if it has any effect on the issue. (It is a tiny cigar box thing, so it is perfectly possible to shake it, and it has a solid state M.2 disk - the only movable part is a fan.)
All good analysis of the problem. I remember way back in the day (building 386 systems) we installed a mainboard into a case. Booted it up and it went crazy in Windows 3.0 and would then crash. We took the mainboard out of the case, and placed it on the workdesk and booted up. No problems. Hmm... Examine the mainboard. Oh, one of the circuits crossed into the standoff hole. When the screw was tightened into the standoff on the mainboard it closed the circuit and caused undefined behavior. Maybe something similar here. Especially since it is a cigar box. Good luck. Hope to hear what you find.

This is not a problem of mine, but of a friend who call me every time there is some trouble with his computers. I will visit him next weekend and need some good hints for the problem investigation. His newest PC, a small cigar box thing, is between 1 and 2 years old, and should be quite modern. (Sorry, I don't have the brand or model at hand.) He is running Windows 10. For a couple of days, the Start Menu has been popping up, and then disappearing, at irregular intervals of a few seconds, as if he were randomly hitting Ctrl-Esc every few seconds. Intervals are not fixed, neither between popups nor how long the menu is displayed. When it pops up, it steals the focus, making it impossible to get any work done. If he opens the Start Menu explicitly (by clicking the Windows icon), and it takes him a few seconds to find the right entry, the menu closes. It sounds very much like a faulty keyboard. But the thing is that if he disconnects his wireless keyboard completely, by unplugging the dongle, the problem remains. The mouse uses the same dongle, and is disconnected as well. I strongly suspect a hardware fault within the cigar box, but I think it strange that a hardware fault has this single effect and no other visible signs. He has tried to do a complete reinstall of Windows 10; the problem remains. In between the Start Menu popups and closes, he has managed to start Notepad to do some simple typing. There is no sign of "ghost characters" that he didn't type himself. There doesn't appear to be noise on the keyboard input line, unless there is some filtering of keyboard input to Notepad that isn't applied to the opening of the Start Menu. When I visit him next weekend, what should I do to try to identify and isolate the problem? (I am not a hardware man, so I have no fancy electronic test equipment!)

If all else fails, try to disable Cortana, or Cortana's access to the microphone.
