I am unable to login to the microsoft apps on my windows computer

I am using Windows 10 computer, no error message. I am unable to utilize the Microsoft Store through the Microsoft website.

Hello Georges, thank you for replying to my question. Yes I have Windows 11 version 21H2. I unfortunately can't download the Xbox companion app due to the problem of being unable to sign into a Microsoft account on my computer. I am able to sign into my Microsoft account on the Xbox and Microsoft website its just the apps I have trouble signing in to.

Same issue. I bought a surface go device and was going to stick to windows for all my computing needs but i am unable to buy any app exclusive to microsoft store. I guess I should have never switched over from iOS / android tablets.

I purchased Minecraft for Windows 10 when it last year. My son's computers are setup with me as the administrator and they are family/child accounts. If I login and download the game, then they can login later and play the game. I am not sure what the
limit is but all three computers are under my Microsoft account. I have not tried it with any other games.

I have 3 computers I used to test this issue. My main computer quickly showed grey box and then back to regular screen. After downloading some other xbox related apps in the Microsoft store, I discovered it was related to my computer using a local account
and the fact I never logged into the Microsoft Store. I refuse to do this on this computer so I tried a different computer. That computer didn't have the May 2019 update and it specifically told me I couldn't configure it until I did that. I then went to
my new laptop and tried it. This computer also uses a local account, and has never used the Microsoft store before. I downloaded the app without logging in (I cancel the two sign in attempts and it still downloads and installs fine). When I opened the app,
it had showed the controller properly and when I hit configure I discovered that the grey box is the REQUIRED xbox live sign-in. You can not configure the controller without being signed into your xbox live Microsoft account. For some reason my main PC is
unable to figure out I am not signed in properly and just crashes. For the new laptop, I logged into my Microsoft account but selected to only use it for the Store apps, not my general windows login. I was finally able to configure the stupid controller.
