Slui.exe doesn't display menu to change product key.
My Windows 10 Pro x86-64 machine all of a sudden had a deactivated key. I called MS Tech Support who got on my system remotely and gave me a new key. Originally I had a digital key when I upgraded from Windows 8.1.
In the course of Tech Support trying to change my key we found out that slui.exe doesn't produce any menu. On a VM test machine it does bring up the change key menu. Slui.exe 3 seems to bring up the same menu and also doesn't work on my production machine. However slui.exe 4 does work on my production machine. This brings up the Country and Region menu. I haven't tried any of number.
All the other ways to change the key don't work either. The one in Settings|Update & Security|Activation is just one example. I assume all it does is execute slui.exe.
I checked the permissions of slui.exe against the one on my VM test system. They were identical. Any idea on how to get slui working again? Perhaps it's a Registry entry problem. For such a minor problem reinstalling Windows is not an option.
Thanks.
