I bit the bullet and installed the newest Windows 11 preview yesterday (after being on the latest Windows10 version earlier) due to my Microsoft wireless adapter not syncing anymore with my Xbox headset (after the later had an update). No updates available, no workarounds helped, so I thought I might as well try it.
I used an old MS Insider account, as my hardware does not fullfil their current processor minimum requirement, but everything else easily.
the wireless adapter and headphones connect again without any issues.
So far have had no issues with web browsing (Firefox, Edge) watching movies with VLC Player or File Explorer and office tasks whatsoever.
Had 1 bug where the taskbar stayed "empty", then was slow to load, but I think that had nothing to to with system requirements and more with it being only the 3rd dev version and naturally not quite bug free yet.
Visually it's a nice upgrade, once you get rid of these good awful wallpapers.
Don't mind the centered task bar, you can still left align it if you want.
So far the only thing I didn't like is there is (at least currently) no way to modify the "Start Menu" and get rid of the recommended section which in my case is black/empty, forcing me to move up higher to click on my pinned Apps and the search bar.
