So, a few people had played a bit with the leaked Win 11... but now that's it's officially out, is there anyone here who has installed it and uses it as a daily driver?
If so, what are your thoughts?
I have now converted all but one computer to Windows 11. Simply because, in my view, Windows 11 is a much better OS than Windows 10 has ever been. And that was true even for the last beta before release.
I know many people scoff at the UI changes, but the fact is that Windows 11 is the first Windows which has a single UI which works equally well with keyboard/mouse on the desktop and with touch interaction. Windows 8/8.1 was too touch-centric (and there were very few native touch apps back then) and in Windows 10 MS converted that to two alternative UIs of which the touch version was actually made worse over the predecessor version.
I also like the cleaned up settings (the various iterations in Windows 10 were a mess). Plus the system sounds are now a lot less annoying
BTW, I'm typing this on a 2015 Dell Venue Pro 11" tablet/convertible which is pretty low-spec (Core-M, 4GB RAM, 128GB SSD, TPM2) and which was originally sold with Windows 8.1. Using it with Windows 8.1 was OK but the lack of touch-capable apps was a problem, and with Windows 10 the whole user experience just sucks. Windows 11 on the other hand, which I just installed out of boredom, has turned out to be the perfect OS for this thing. The UI works absolutely fine, and for the first time even the changes between the different modes (tablet, laptop, docked/desktop) work seamlessly. The performance is fine for standard web/office/Netflix stuff, the batteries last longer than under Windows 10. Thanks to Windows 11 the tablet is no longer collecting dust but is now in active use by myself and others (without Windows 11 this thing would still be sitting in a drawer, unused).
As to the other PCs I installed Windows 11 on, these are all officially unsupported systems (I did only fresh installs, no upgrades, but also did not use any hacks/workarounds). The oldest PC is a HP z620 Ivy Bridge E XEON workstation with TPM 1.2 and Geforce GTX 770. Windows 11 runs completely fine, including TPM support and even HVCI enabled. There are several Haswell E machines with TPM 2.0 and newer Geforce and Quadro graphics as well. All work just fine and better than Windows 10 ever did. The only exception is one machine running Windows 10 Enterprise, and this one is only waiting for the Win 11 Enterprise version to become released (which will be early 2022).
One thing I should mention is that HVCI, which even on Ivy Bridge only causes negligible performance loss (tested and found less than 5% under various benchmarks), only works when all drivers follow the DCH model. While this is the case even for older Nvidia cards like my GTX 770 (for which there's a Win 11 driver from Nvidia), the drivers of older intel graphics variants seem to be stuck with the classic driver model. As a consequence, HVCI can't be enabled if the system has an intel iGPU, unless it's a newer one (Gen 6 or newer I believe).
