Tiny11?

I would not recommend any windows mods like that, what they do is often overwritten by windows updates and takes you back to square one (which, unless your computer never connects to the internet, you should be installing). the better option for "light" windows is to grab an enterprise or education version of windows and set group policy to disable telemetry and various features you don't want/need without ending up with changes that revert themselves if you go the tiny11 route, or with changes that actively compromise security if you go the atlas os route
