W8.1 x64, happens in both laptop and desktop PC.
I can confirm this under Win 10 x64.

Same problem, Win 7 x64 bit.
Actually, it opens Update window and one more normal interface. Seems like someone by mistake tied opening of main interface command to the Update engine and signatures trey button…
Thanks for reporting this. I just opened ticket for it in our bug tracking system (AV-11986 - Opening Settings/Update from tray context menu causes opening of main UI).
17.1.2283 still has this bug/glitch. Should be in “Known issues”, no?
