I am using Windows 10 Home.
The Store fails with Code: 0x80131500
I tried the various suggestions to fix this.
Eventually, I discovered the reason was my location was correctly set to Guernsey.
When I lied and changed it to United Kingdom, the Store no longer gives the error.
Guernsey is not in the UK but does used GBP currency and we use English (UK) as our language.
This problem probably also exists for Jersey.
The base of this problem goes back to the earliest versions of Windows 10. Windows 7 did not have Guernsey as a known location.
Thanks Andy
I have Windows 10 Home in S Mode and was trying to switch out of S Mode following the instructions which included clicking on a link to the Store. I got the same error code and couldn't make the switch. Contacted Microsoft Support and none of their solutions
worked. On reading your post I checked my region settings and they were wrong. I corrected them and was able to complete the switch.
