This may not be possible, but Start11 has made Win11 useable again, so i thought i'd just put in a feature request. 
The new dumbed-down file manager ribbon replacement is nonsense. The registry hack that used to bring the ribbon back no longer works (and broke other things anyway), and my current work-around (start control panel, hit the menu bar up arrow twice) works, but the result has no tabs.
For me, the ideal file manager would be like the Win10 file manager + Groupy, but downgrading to Win10 would cost some of the functionality in WSL so i'd rather not.
3rd party file managers either really stink or cost more than I care to pay and still stink.
thanks!
