If you have a look at the right click menu against a file in File Explorer, it will be a much shorter list than what you’re used to. Several common functions (cut, copy, rename, share, delete) are icons at the top, but everything else that didn’t make the ‘cut’ is in the ‘Show more options’ menu, which takes you back to the classic looking right click menu.

Command Prompt

File Explorer had a bunch of useful options in the top Command Bar. They’ve mostly been removed (seeing a trend here?) to simplify and show only a few options. The idea of tabbed menus is completely gone. Some options like ‘Map network drive’ are in an ellipsis menu
