After a fresh Windows 7 installation, I needed 3 hours to configure security and privacy. With every subsequent Windows version, it has become increasingly worse. With Windows 10 and 11, I needed weeks to inform myself about good configurations of security and privacy so that then, after a fresh Windows installation, I can configure both within one day, taming almost all telemetry. Besides, Windows 7 did not need later checks while Windows 10 and 11 need later checks whether major Windows updates reactivate some telemetry without user consent.
Compared to Windows 10, Windows 11 has introduced a few new bugs, which have not been fixed yet. The most annoying bug does not always log off users properly.
After debloating configuration, the Windows 11 GUI is still slightly bloated, especially the empty start menu is ridiculously large. Not nice, but I can live with the GUI.
Microsoft ought to have simply adapted Windows 7 to newer hardware.
