Have you tried reinstalling a clean copy of Windows? That was the trick for me. Did that and it worked straight up. To get the latest update just a few days ago i got a vague error about needing to go to the windows store for an update and when I went there it wasn't showing anything. I then saw I needed to have the xbox app installed and as soon as I did that the update came straight on.
You could spend a lot of time chasing this issue. Just bite the bullet and re install windows...
Quentin, I agree a new OS install probably will fix it.
However, I refuse to do that on a working system.
MS Store works with everything except MSFS2020. I have sent all the logs and error codes to MS, and nobody tells me what the errors mean, or how to fix.
The installer is broken, not my system.
It will take me about two days to reinstall everything back onto a new build. I have FSX with full UK scenery and addons, a full DCS install with many modules.
Plus loads of other apps' and things like VPN's for work.
WIN-11 is nearly here, when that is stable I probably will bite the bullet.
I am an enterprise level server and network engineer. I have worked in IT for 25+ years.
Disgusted at the lack of customer support from Microsoft.
