I have not seen the advantage of the front end of windows since Windows 7 (and that a little improvement over windows 2000). Win2k has a performance improvement. Win95/98 used to crash.
Each time I get a new Microsoft Tax excuse I have to spend a while making it more like those earlier versions with a normal working menu and task bar and less Microsoft publishing to my computer screen.
Windows 11's middle bottom of the screen thing is especially annoying. I have not the slightest interest in being "modern."
I use a Russian program, Startallback at $5 per PC, to put the taskbar and menu back to the top left. Before that I used a free Russian program StartMenuX to modify windows 10 to get rid of the enormous "modern" space-wasting menu.
I would have moved to Linux (20 years ago, it worked fine) but my students are still encouraged to use Windows. Maybe the back end of Windows, threading, processes are improving. Since I use PC for Office (and now online AI) it does not really matter. My needs are not modernising.
Now that it is becoming possible to run AI on ones own PC, the back end, multiprocessing and GPU use improvements will (I presume) be useful and I will thank Microsoft when I enjoy that ability. All the same, since a long time ago, and into the future, I wish Microsoft would allow us to select any previous GUI that we, the users, desire.
I do do some video editing from time to time as a hobby and I think that the more modern versions of Windows are better at video processing. If I could upgrade one of my 7 PCs to the the latest multiprocessor version of windows that would be fine. The rest of my PCs are used for the modern human tasks of typing, presenting, and calculating.
I have not grown any new arms nor legs, nor new needs in the past 30 years. My use of computers has not "modernised" so what is the "modernisation" of windows providing?
