Windows Terminal can be installed separately on the last Win10-based LTSC and Server editions at least (and it works as a full replacement for the regular Win32 console as it should). Did they prevent it from working on the last regular Win10 version?
You could, but like he mentioned, since it comes pre-installed with 11 you have an easier time running it in a corporate setting. Though I think that the last versions of 10 also shipped with it by default. I know that Win10 has been shipping with winget for a while so it's a very nice way to install software across the board.
It also features a Quake-style quick console which was recently adopted by Oh, Marky!
The Quake-style console was a thing long before Windows Terminal was a thing. For example ConEmu had it. Though it has one annoying issue, you can't filter it for shit like GlazeWM so it will be tiled like any other terminal window. There is a hacky way to do it by detecting the Win32 window styling (as it's probably the most reliable way to discern between a Quake style window and a regular one) and adjusting the title bar so that it gets filtered. I vibe coded a Powershell script for that but it's not perfect. Ideally wt itself would change the internal window class or something but no one at MS seems to want to do that.
As for things that Win11 did improve upon:
-WDDM 2.0 with it's WGC is great for Lossless Scaling and gaming in general
-Auto Color Management is fantastic, I didn't even realize what it could do and it made the washed out 45% NTSC screen of my ThinkPad actually look more like sRGB, even if it overshoots many colors but it's much nicer to use now
-the Quick Actions menu looks more like a smartphone menu but it's a good thing, it's more usable on a laptop
-The new WinUI3 Settings are much more pleasant to use than the old Metro/Modern Win10 ones
-Mica is much prettier than Acrylic, that's for sure. Probably the prettiest UI engine since Aero (ofc Aero is still #1)
-the Snap layouts are basically PowerToys FancyZones Lite, and in a way more ergonomic than FancyZones as you get a few premade layouts to choose from instead of one hard set to a given monitor
My first proper personal experience with 11, not toying in a VM or working on someone else's computer, was on my ThinkPad. It's overhated. The shitty UI changes aren't world ending. Everything points to the only logical explanation: people just want to be mad about something in perpetuity. Win11 is a mixed bag of good and bad changes, yet people love to act like this is
the Windows release that's so bad that people'll leave Windows en masse. Yeah nah, for all the fuckups that Microsoft has done, Win11's UI is one of the smaller ones. Cuz under the hood it's about as stable as Win10. Meaning that if you didn't have issues with 10, you won't have issues with 11. If your hardware is some unstable combination or your RAM is dying, you'll have problems no matter what. If your system is a-OK, it'll be rock solid.
By the way, the newest Patch Tuesday finally replaced the Win8/Win10 throbbers after 5 years of 11 being out and they finally added the ability to resize and move the taskbar. Except if you move the taskbar anywhere but the bottom auto-hide won't work. And it's all A/B shit you gotta enable with ViVeTool. It's worth reminding that
RetroBar is a non-invasive replacement for the system taskbar. It hides the system one and shows it's own, and it's about what you'd expect. Just do keep in mind that it won't show the network icon on 11 as that got removed for the integrated Quick Settings one, but in my case I just Win+A to open it up when I need to manage WiFi connections. Then again I use a completely different workflow with a minimal status bar so
