At work I am made to use Windows 11 and I hate it immensely. Everything's so slow. Nothing operates properly. In addition to forced reboots which are annoying as hell, it also reboots after some time on sleep, for no reason whatsoever. Copilot is everywhere and cannot be truly disabled without admin rights. While not strictly a Windows issue, Outlook is an incredible piece of garbage. It doesn't know if it's running and so can be launched more than once; the icon for new messages doesn't show when it should; search is still as broken as ever; the ribbon, which makes little sense in other Office apps, is absurd in Outlook; folders are useless and confusing; etc.
At home, while I have a Mac Mini 4, a MacBook Air, and several Linux boxes, I still use an old PC on Win7 as my primary machine. Is it insecure? Probably. But today "insecure" feels more like a feature than a limitation. No forced updates of anything => everything that works, keeps working indefinitely.
