How do I sign in to Store?

I think I did not - this policy is not defined.



Is it possible I messed something up in Group Policy?

I'm certain I didn't do that? but I'll check.

Edit: does not look like it.

Well, I just installed it recently on a new machine, so I'll try to avoid this if possible. Perhaps I'll backtrack everything I did and see if it's me or if there is a real glitch somewhere (not that I really believe in those). Thanks for your help though!

It appears my other machine does not have this problem, I do have the setting there to add another account for apps. Now, is there an easy way to compare the settings on two different machines? I realize that there are quite a lot of different settings, so comparing everything manually may take forever. Is there a way to export all, say, group policy settings into a file that can be compared to another such file from a different machine?

Looking at my other machine I noticed the following: that machine has two users on it, one a local user and another signs in with a Microsoft account. The option to add a Microsoft account for use with apps exists for user with the Microsoft account only. It does not exist for the local account. However, using that local account I still can sign in into Microsoft Store! Which means, the problem is not in the absence of the option to add an account, but probably in some other settings.
