Completely agreed: there are way too many outstanding issues in Windows that don't get fixed but have been present for years.
- file explorer UI lag and crashes
- stupid rules about logons (i.e. when no password is present)
- dual screen issues: blurry apps, poor scaling, icons with wanderlust, ...
- settings and control panel hell (jeez, what a mess!)
- declining customization of UI colors
- update issues, loss of control
- poor control of of rights for non-admin users
- declining and confusing (local) group policy use in Windows Pro
- complete decline of parental controls in Windows 10 (now requires an MS account for the kids, really?)
- confusing versions of Windows 10 (Pro is hardly pro anymore, is it?).
- .... on and on,
Come on MS, get your act together!
