Windows 10 update created a recovery partition - How to hide that partition?

I encountered this same problem after the Windows 10 Spring 2018 update. I was unable to unassign the drive letter according to the instructions from Tiago Caldeira that used Disk Management, however these command line instructions did work for me:

  • Open Command Prompt in Admin
  • Enter diskpart
  • Enter list volume
  • Enter select volume [number of your volume]
    • For example: select volume 0
  • Enter remove letter=[drive letter of your volume]
    • For example: remove letter=f
  • You should see the message DiskPart successfully removed the drive letter or mount point.

I hope this information helps!


I think that just unassigning the drive letter will do the trick:

  1. Open Computer Management on the local computer by right clicking on Computer in Windows Explorer and choose Manage. Then click on Disk Management in the left hand pane.

    (Or just type diskmgmt.msc into the run dialog)

  2. Right click on the shaded area for Drive D: System reserved (or whatever the name is / letter) in the lower right hand window.

  3. Click on Change drive letter or paths

  4. Highlight D:(letter of the partition) and click remove

If you receive error messages that the drive might be in use or that programs might not run correctly, don't panic. It is OK to remove the drive letter. Once a letter is not assigned, the drive will not appear in Windows Explorer.

Hope this helps!


Run this on DOS Prompt running as administrator:

mountvol X: /D

Change X: to the assigned drive letter. Done.
