I did some study about the problem. And I know what goes wrong with those apps during their update.
With command prompt as admin
dir “c:\program files\windowsapps” /a
you can see what version you have of the apps
On a pc who has (for already some time) Store troubles that is
And then regedit:
In the registry branch HKCU of the user with the broken store there are 129 references to 2015.25.22.0 instead of 2015.25.24.0.
On the same pc the user with a Store that works fine: all nice references to 2015.25.24.0
(I found some other minor differences too between the Store lines in the branches of the different users.)
Conclusion: The registry is referring to files that do not exist. The installation of the apps is not okay. It does not execute all needed modifications for all users. It only does the needed registry modifications for some users.
I verified the conclusion on other computers. I have plenty of computers to check it, and they all have wrong registry references for the user with the broken apps.
Okay … now we know what’s wrong. But how can it be solved????
Somebody an idea?
