Windows 10 1803 April Update automatically creates a new “Recovery Partition”. The files and folders in that “Recovery Drive” are out of bounds and remain invisible to all file managers. That “Recovery Partition” is still given a Drive Letter. Would there be any way to hide that useless drive letter in xplorer² Drive Bar?
TIA

I found a solution to this at How to Remove Phantom Drives:

command promt as administrator
diskpart
list volume (you can now see which volume has letter)
select volume x (x is the volume number of the letter you want removed)
remove letter=x (x is the selected volume letter)

This did the trick!
