hi szuguan,
What you need to do is easy, you launch dispart, you execute the commande "select vdisk file=<VHDX>" and you execute the commande "expand vdisk maximum=<New size disk>" and after that you attach the disk in disk manager and extend the disk.

Hi, it looks like the issue is that there isn’t any unallocated space immediately following the partition inside the VHDX. When “Extend Volume” is grayed out in Disk Management, it’s usually because there’s no adjacent free space available.

For Diskpart, instead of using “list volume”, try “list partition” after attaching the VHDX. Often, especially in VHD files, the partition you need to extend appears in the partition list rather than the volume list.

Try these steps:

Attach the VHDX:

select vdisk file="PathToYourFile.vhdx"
attach vdisk

Check for partitions:

list partition

If you see the partition you want to extend, select and extend it:

select partition X
extend

(Replace X with the correct partition number.)
Additionally, ensure that:

-The VHDX file itself has been expanded (right-click > properties in Hyper-V or use PowerShell).
-The partition inside the VHDX has space to expand.
-If there’s no unallocated space, you’ll need to first increase the VHDX file size before extending the partition.
