Yes, MS did hide the drive letters.
Been a long time since I set up Win10, but from what I remember:
- You can rename "My PC" to "My Computer" (at least that's what shows on my Win10; try right clicking the icon & renaming)
Anyways, do this:
Open "My Computer" (or in your case "This PC")
- Select VIEW (at top)
- On the right most side select "OPTIONS"
- Select "VIEW" tab
- Look for check box "Show Drive Letters"
Good Luck
