So I guess my question is am I missing something, or will I need to do a clean install of Windows 10 and use the new Pro key during the install?I just found out that if you have Windows 10 installed and have already done the Fall Creators Update, if you try to switch to pro you will get this error and you will not be able to move forward. So I guess my question is am I missing something, or will I need to do a clean install of Windows 10 and use the new Pro key during the install? I should also mention I tried uninstalling the product key to deactivate Windows using the command 'slmgr /upk' and 'slmgr /cpky' but that didn't help. However, the 10 Pro key I purchased is OEM so it should work, at least in my mind, unless there's something I'm missing. This was two years ago, or whenever 10 was released. Once the system was upgraded to 10 I formatted the drive and did a clean install of 10. Windows 8.1 was updated from Windows 8 OEM, so Windows 8 Home -> 8.1 -> 10. The only thing I can think of is that my currently installed copy of Windows 10 comes from the Windows 8.1 upgrade path. If you think you do have a valid license or key, select Troubleshoot below.

Check the product key and try again, or enter a different one. Over the weekend I purchased a Windows 10 Pro key to upgrade the system, but when I go to enter the new code I'm presented with the error: The product key you entered didn't work. I have Windows 10 Home 圆4 (latest version) installed on my PC.
