Several of these features are already available in current Windows versions (perhaps less discoverable, but there nonetheless):

- "Add to favorites" is an option in the right click menu on Favorites in the left panel, works the same way as the new one on the ribbon shown in the article - "Run each window in a new process" has been around since at least XP - "Open command window here" is in the shift-right click menu already

On the other hand, several of the new features do look nice; (re)adding the Up button is good, and "Copy path" sounds very handy.
