You might be interested in the LTSC versions of Windows 10. I know you said Windows 11, but IMO, Windows 11 currently is missing some usability that's still present in Windows 10 (like the taskbar). Of course you'll also be missing the scheduler updates, but I've witnessed some users disabling efficiency cores on Alder Lake anyway due to bugs or performance.
> LTSC, Long-Term Servicing Channel (which was until 2017 branded as LTSB, Long-Term Servicing Branch), is a unique version of Windows 10 Enterprise. Unlike all the other versions of Windows 10, LTSC has zero bloatware and the least amount of telemetry (data being sent back to Microsoft).
