Cannot activate Win10 Pro after Microsoft Store app purchase

Well that's a bit of a mystery to me. If this was a legit purchase, I suggest you call Microsoft and find out what the issue is. Something doesn't sound quite kosher here. Not saying you've done something wrong, but something doesn't seem right to me. And I've never bought an OS from the Microsoft Store, but I'd think you'd still be emailed a license key. You might also check your Microsoft Account to see if the key was posted somewhere there. Good luck.

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:

Unable to Activate Win 8

I got Win 8 isntalled on my file server, but I am unable to activate it with the key. Says the key is invalid. Since I work at microsoft I got a retail version from the employee store. I have been doing some reading, and to be able to activate Win8 with the key there needs to be a previous version of Windows installed for it to work. WTF, so you can't do clean installs?

And the box says nothing about Upgrade version. Straight Windows 8 Pro.
