I purchased a Windows 11 Home product key directly from Microsoft yesterday, and it worked fine at first. However, today I encountered an issue where it says, "We can't activate Windows on this device because the product key was already in use on another device." This is confusing since it was working perfectly just yesterday. I've tried restarting my computer, but the problem persists. Additionally, the activation settings show that I have Windows 11 Pro instead of Home, and I couldn't find any specific download options for Windows 11 Home on Microsoft's site. Can anyone shed some light on this?

What does the seller say about this? They should provide some sort of support if the key isn't working as it should.
First off, make sure you bought a legitimate key from Microsoft. If you did, then contacting their customer support is your best bet. They'll be able to sort this out for you. If the key was from a third-party seller, though, you might be out of luck and need to get a new one directly from Microsoft instead.
Lol, who buys Windows keys anymore when there are other ways to activate it? But if you paid for it, definitely follow up with Microsoft—it's your best option.
Honestly, just call Microsoft! You spent more time writing this post than it would take to get in touch with them and get help. They'll help you get it sorted quickly.
If you bought the key from Microsoft and it's showing as already in use, contacting them is crucial. They'll have the best insight into your specific issue with their product.
