For NTLite forum, we don't support external custom ISO projects since they have their own devs, or Discord groups. Some like Atlas OS, provide you with a working NTLite preset, but others are closed source.
Tiny11 and other stripped ISO's belong in a group which are generally considered as "over stripped". Meaning to get their results, they've removed too many useful features and you can't update most installed systems. They're only useful as teaching examples.
NTLite's core philosophy is always start with the default Windows ISO and know what you've modded. You can't keep modding a stripped ISO, since the previous removals are permanent.
If you want to learn which components they removed, and some of the tweaks; you can use NTLite to create a reverse preset.
1. Open CMD and run:
NTLite.exe /forcelistcomponents /saveallstates
2. Load the modded ISO. Preset / Save As -> filename
3. Quit NTLite.
Don't run NTLite in /forcelistcomponents /saveallstates for normal use.
4. Run normal NTLite.
5. Load a clean Windows ISO, load the previous preset. Now Preset / Save As (again).
This is a preset recreated from the modded image. It's not a perfect copy, but will list the different features or components they've changed.
Should you use this preset? No, unless you have the experience to understand what they removed, and why it's important.
GamerOS, while not as stripped as Tiny11, is considered a better baseline. Not because it's the best -- but because it gets the most feedback of any user-shared preset on how to fix its flaws.
