Windows 10: Why is my Windows 11 pro Key not working?

I currently have Windows 11 Home activated on my device, a Windows 11 Pro Key ready to be activated and it's just not working.I tried Putting the product key in, errors came up every time.Then I imaged my device with the disk that came with it I had a new disk reader handy, lol didn't think I would ever use it. After imaging it again similar errors keep showing up, the current one is 0xc004f050 What I look into and it just says its wrong lol.I paid $329 for this Key from Micks Computers. For that price I would expect i can at least talk to someone I spent 10 minutes going through almost eve

Windows 11 Home to Pro upgrade

Want to upgrade 11 Home to 11 Pro. Tried download, but apparently files transferred were for 11 Enterprise. This will not activate; error is "invalid digital license or product key". This is on a new Surface. How to proceed?

Can withdraw/delete this. The suggestion to downgrade - listed below - with a 'fake' windows 10 key works.

 

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

Upgrade Windows 11 Home to Pro using existing Windows 10 Pro key

Hi there.

I purchased a Windows 10 Pro license from Microsoft online back in 2015. I was e-mailed a license key which I still have. I've been using this license on a Parallels virtual machine on my Mac. I will soon decommission this virtual machine and I will be purchasing a new Windows PC with Windows 11 Home installed on it.

I plan to do a fresh install of Windows 11 Pro on my new machine and I was hoping to use my existing Windows 10 Pro license to activate it. From reading the forum it seems this should work. Any suggestions on steps I should follow? I see talk of people activating with a generic license key and relying on your Microsoft account to recognise you have a digital product key?

Thanks.
