Tiny11 looks very sus honestly, you shouldn’t trust random ISOs. Even if the dev may seem trustworthy, it is really hard to know if the OS is infected.
I’d recommend replacing Tiny11 with AtlasOS, which is open-source :)
Edit: You should also consider just installing regular Windows 11 and then running winutil, so you can get a more secure system while still having removed a lot of stuff
Oh, last time I checked they did distribute ISOs, my bad
