The Windows 11 desktop. Again, not largely different from Windows 10, but different enough.

Obviously the biggest change is the new center-alignment of the start menu and main taskbar area. I suppose this is done to cater to people with theater screens for monitors, since that's popular these days. It may also have been done because the Mac OS has a center-aligned Dock, but M$ is about 20 years too late to that party.

It's also worth noting that the colours were brightened significantly, and it appears Windows now defaults to a light theme. I guess they got tired of catering to a generation of emo teenagers. Or realized that particular fad died in the '90s.
It's also no longer possible to display things on the taskbar "ungrouped", so you are forced to get along with the tiny Dock-like icons forever now. Not that I think anyone ever turned that off from the Windows 7 days to now anyway, but it was nice to have the option at least.

Here is the taskbar left-aligned as is right and proper, and it doesn't even look that out of place either! I'm surprised that they allowed this option to remain in the final version.

Here is a look at the new start menu. Thank god all those stupid tiles are finally gone, but we aren't left with much by default. You can of course choose which applications to "pin" here. I am shocked that functionality was also allowed to remain.

Clicking on "all apps" gives you this. I'd still like for some kind of hierarchy to be possible here, but I guess that we're long past the point where someone's going to add it.
