For those who really want the old ribbon..
create a batch file in notepad something like this:
c:
cd c:\windows
taskkill /f /im explorer.exe
start "" C:\Windows\WinSxS\amd64_microsoft-windows-explorer_31bf3856ad364e35_10.0.22621.608_none_b3fd0d5042b63bbd\explorer.exe
exit 0
Save to the desktop or wherever.
Create another one replacing the long command with:
start "" C:\Windows\explorer.exe
Save as "Exporg.bat" or whatever you like.
The first batch will end explorer and open it again only now the ribbon will appear in all instances when you open them.
The second batch will do the same in reverse, restoring the new ribbon. You can add the first batch to the "startup" folder and it works fine. Classic Shell works fine with both. The only downside for me is that "explorer patcher" gets kicked out with the old ribbon which means there is no context menu on the taskbar on right-click. But it is easy enough to swap back and forth using the batch files.
It's clunky but works for now!
