Answer 1

Hi, I had success today . I am resurrecting a 10 year old gaming PC ( an ASUS P6X58D_Premium board, and an i7 980X Extreme processor. Windows 10 proved challenging to find a downloadable version I could buy online. So I went to the computer store, and bought a local Retail copy of Windows 11 Home. I tried to install Windows 11 but the installer pretty quickly told me that my CPU was not compatible with Win 11.......very weird , since the 980x extreme is 6 core, and 3.33 Ghz !!!! Anyhow , I was able to create a Windows 10 USB installer drive with the MediaCreationTool22H2.exe Utility. When I used the USB to start the win 10 installation, which supports my CPU, my brand new Win 11 Key was accepted !!! I very pleased with this outcome!! :)

Yes you can go back and forth as licensing data is entered into Microsoft servers. The best option is to use free or pay third party software to make backup images. (Acronus, Aoemi, EaseUS, Macrium, Paragon, etc ) Then you can restore an image as needed.

Answer 3

It is not possible to activate Windows 10 using a Windows 11 key. However, if you have a retail version of Windows 11, youcan use the product key to perform a clean installation of Windows 10 and activate it with the same key. You would need to create a bootable USB drive with the Windows 10 installation media and perform a clean install of Windows 10. Duringcan try upgrading from Windows 10 to Windows 11 without losing your files and programs. To do this, follow these steps:

1. Go to Settings > Update & Security > Windows Update and click on "Check for updates".
2. If your PC is compatible, you should see an option to upgrade to Windows 11. Click on "Download and install".
3. The upgrade process will begin, and your PC will restart several times during the process.
4. After the upgrade is complete, you should be able to activate Windows 11 with the license key you purchased.

Note that upgrading to Windows 11 may not be possible on all PCs, especially older ones that do not meet the minimum system requirements. Also, upgrading may cause some programs or devices to stop working. It's always a good idea to back up your important files before making any major changes to your PC.

Answer 4

AFAIK, Windows 11 product key won't activate Windows 10.

Answer 5

Product keys were required for Windows 7, 8, and 8.1.

Starting with Windows 10 licensing data was entered into Microsoft servers during Windows updates.

Once licensing data had been entered into Microsoft servers this enabled clean installs of Windows 11 to Windows 10 or disk drive replacements.

It's always best to make free backup images so that you can quickly return to where you were before the change in operating systems.
