So after using Windows 11 in both a virtual environment & on a spare laptop thankfully they do allow the customization of the taskbar to move it back to the left hand side (where it belongs).
Funnily enough the News & Interests hasn't made it to Windows 11's Dev Builds (yet). Hopefully it was just a Windows 10 experiment that was yet another Group Policy edit for us Sysadmins to make.
The virtual desktop experience has improved from 10 so far, it does help being able to customize each as its own desktop environment.
Overall performance is definitely a step up from Windows 10 as well, considering it's still in Dev stages the startup speed and overall memory & CPU utilization management seems to be more stable than it's predecessor.
I'll continue to dick around with it at work and see what changes with each update. Definitely excited for it's full release though.
