A long time ago, I wrote about How to hide an entire drive from prying eyes on Windows 10 | Windows Central.
The easiest way is still to add/modify a NoDrives value in the Registry, but regrettably [WayBack] NT Drive Calculator – The ‘NoDrives’ Registry Key Value Calculator is down (it was a server-side solution, so the WayBack Machine link does display a page, but the calculator does not function).
My use case is that I have an existing NoDrives value that I want to update (as there have been one or more drive letters added/changed).
