Solved Cannot delete VHDX as it's open in SYSTEM

CSharpDev · Feb 18, 2024

I wanted to use this on my MDT server but failed as I forgot I had to take the entire physical HDD offline first to then use it in the VM. Anyway I wanna delete this VHDX but can't. What can I do to override this and delete?

Edit: Solved

If your vhdx is open in System it's almost certainly because you currently have it mounted as a virtual drive. Detach it, then you can delete it.

One way to dismount a virtual drive is to right-click on it in File Explorer and select Eject. Another is to right-click on the drive in Disk Management and select Detach VHD.
