Overall I do really like the new UI, but the lack of taskbar customizability does indeed suck (I used to have it at the top, but now that I'm forced to have it at the bottom I've set it to auto-hide). The Settings menu on the other hand is leaps and bounds better than the absolute garbage that is the Windows 10 Settings menu (except for the default app mess but hopefully they'll improve that).
I’m blocking the Windows 11 update via group policy[1] until the Taskbar and Start Menu are usable.
I run software that is unusable without it being 1-taskbar-button-per-window. Forcing us to use 1-button-per-EXE with a slow-and-fiddly window sub-menu is so very user-hostile.
I suspect the decision to force single large buttons was to prompt third-party developers to have single-window-apps just like smartphones and tablets - which is just so wrong on so many levels.
Being dicks about MSAs in Home SKUs is also inexplicable. Do they really expect people will be okay with being stuck and unable to install Windows without a working internet connection? What if a computer has a modern NIC that Windows doesn’t have in-box drivers for? This. Is. Insane.
Same, though I don't run an AD domain (you can still use gpedit.msc on a local machine). I'm also considering turning off my TPM in case Microsoft screws up the roll-out, intentionally or not.
