Upgrade from 8.1 to 10. No Microsoft Store and no "Modern" Apps


I just upgraded a reasonably new Dell XPS from Win 8.1 to Windows 10 Home. The upgrade appeared to progress normally but when finished I couldn't find any "modern" apps and then I saw that when I clicked on the Store icon. I get a message that there is a problem with the Store and to contact my system administrator. That's me and I don't have a clue I've tried may suggestions found surfing but no success.

Any insight appreciated.*Mad

 

Cannot activate Win10 Pro after Microsoft Store app purchase

Hello guys,

My laptop came pre-installed with Win10 Home 64bit and I recently purchased a Win 10/11 Pro licence from the Microsoft Store app. Unfortunately, having some issues activating the digital licence for Win10 Pro.

Here is the situation:

• Logged into Microsoft account used for the purchase (also received the email receipt of the purchase)
• Already connected to stable internet

What I tried so far:

Entering the Win10 Pro generic key:



Received error 0x800700005:





Clicking Close returned another error 0xC004F034:





Clicking Troubleshoot re-activated my Win10 Home so still not on Pro.

Thanks for any help.


[FIXED]

Win 10 Pro suddenly became Win 10 Ent from MS Store app:
