The last official release dates from fall of 2020.
Updating of Open Shell has not been particularly active, and the last time I tried using Classic Shell (which can still be downloaded) in Win10 it still worked.
Sent an email to StarDock asking if there's a special version of Start11 available to PC techs that can be installed on an unlimited amount of machines. A technician's license.
I say the following not to be snarky toward you, but it is snarky: Good luck with that. What you think "proper," I think "insane." Lather, rinse, repeat for God-knows-how-many techs with every bit as many opinions.
My approach is use what is native. Go with the flow.
I'm not at my Win11 machine, but I did see something that suggests that Start11 will be (if it's not already) available in the Microsoft Store. Whether it's free or not, I don't know, but it is worth a look.
Start11 is pretty slick. I am back on Windows 10 and not using it.
I upgraded to Object Dock from the same company and am using Groupy to put all my open windows into a single window with tabs to switch between them. Works so good!
