Windows 11 has got to be the worst Operating System I've ever used in my life

I've been using Windows since 3.1 and can tell you that Windows 11 has to be the biggest stain on Microsoft.

I have compiled a list of issues I have with Windows 11 and agree with the items you have also mentioned. Some issues have remained since Windows 2000 which microsoft have failed to fix.

I have moved from Microsoft O/S with Windows 11 making it a easy decision. At home I moved to Ubuntu and its been a significant uplift which actually blows my mind.

As advised (leveraged AI to make these clearer)

Windows Issues:

1. Windows has never reliably remembered multi-monitor layouts or display configurations.
2. Audio randomly breaks: default devices change, services stop, or sound just disappears with no warning.
3. Clipboard history pastes old entries or fails to update properly.
4. Windows 11 removed or redesigned core UI elements that actually defined Windows — especially the Start menu.
5. Privacy is basically nonexistent, with telemetry, AI features, and cloud syncing enabled by default.
6. Control Panel still works better than Settings, yet functionality is awkwardly split between both.
7. Start menu search insists on launching Edge or web results instead of local applications.
8. Teams, SharePoint, and OneDrive syncing is unreliable, confusing, and frequently broken.
9. Traditional Blue Screen error visibility has been reduced, making real troubleshooting harder.
10. Microsoft acknowledges many “known issues” but leaves them unfixed while shifting focus to AI and telemetry.
11. Windows updates regularly break drivers, applications, or previously stable systems.
12. Context menus hide common actions behind extra clicks (e.g. Properties in File Explorer).
13. Registry edits are still required for basic power-user functionality.
14. Sleep, hibernate, and general power management behave inconsistently.
15. VPN clients frequently break after Windows updates.
16. High-DPI scaling is inconsistent across applications.
17. Taskbar customisation is significantly reduced compared to previous versions.
18. Windows sometimes removes applications without notifying the user (e.g. Guitar Pro disappearing with nothing logged in Event Viewer).
19. Microsoft products occasionally fail to update for long periods (e.g. Edge stuck on 1.33 while 1.56 exists).
20. Volume adjustment sounds loop repeatedly instead of scaling cleanly to the selected level.
21. File Explorer increasingly behaves like a web app — clicks misfire, paste actions register as delete or move, and basic interactions feel unreliable.
