Change Windows Edition

You can find this option in the MAS extras section.
It can change the Windows 7-8-8.1-10-11 and their Server equivalent editions.
The script incorporates 4 methods for edition changing:
- May's DISM Api Method - Used in Windows 10/11 Core to Non-Core edition change
- slmgr /ipk Method - Used in Windows 10/11 where edition license files are already there
- DISM Method - Used in Server 2016 and later server versions
- CBS Upgrade Method - Used in Windows versions before 10
Available editions that can be changed to are shown in the script based on all these 4 options.
The script is future-proof, which means that it won't need an update upon the release of new Windows / Server editions and can get the required product key from the system itself.
The script blocks changing to CountrySpecific, ServerRdsh, and to/from CloudEdition editions since it's officially not supported and the user may face issues.
The script cannot change,
- Non-Core editions to Core editions (For example, Pro > Home isn't available)
- GAC editions to LTSC editions (For example, Enterprise > Enterprise LTSC isn't available)

Manual Edition Change

If you want to manually change the edition instead of using the script, please follow the steps below.

To view the list of available editions, open the command prompt as admin and enter
dism /online /english /Get-TargetEditions
Get the keys for the desired edition from here
If you are upgrading from Home to Pro, you will need to disable the Internet before performing the upgrade.
Now enter that product key with this command, replace <product_key> with the actual key.
changepk.exe /ProductKey <product_key>
In the Home to Pro upgrade, it may show an error, restart the system anyway. (Use the script if it's still not working)
Activate the changed edition with MAS, that's all.

Follow the official Microsoft guide here, you can get the required keys from here.
