Best is to see what the popup in the tool states when loading the image.
Plus File - Manage License, top banner.
The official answer is:
- currently supported/tested build is 18309, latest always listed on ntlite.com/features (at the bottom)
- currently testing 18317, will update the tool sometime next week if needed, or I can ping you here if all good.
If you don't remove a lot of components, it should be safe, that's the only thing that can change in such a small Windows version jump.
- if your license's new features subscription date expired, then you need to renew before, as new Windows version support is a premium features refresh, more info on the ntlite.com/shop (below under Support and Upgrades).
Let me know if you have more questions, thanks.
