Im here to spread the good word for those who need/want to still use Windows, look up W11 IoT Enterprise LTSC.
Things it doesn't have: Recall, copilot, ads, cortana, TPM requirement, secure boot requirement, ms store, XBOX and gaming services.
Once it's freshly installed, it's like a fresh XP install, naked. Can even group policy to turn off all telemetry. It's fantastic for gaming.
Since they refuse to license it to just anyone, check out massgravedotdev.
