That "same uniqe ID" problem is weird

Normally there is no "same unique ID". The way to create those: Make a new virtual disk, and then copy the VHDX / VMDK instead of creating a new one.

Doesn't change the diskmanagement tool bug, which is serious, since it should always go by the internal index and not unique ID.

The above mentioned "clones" usually have the same serialnumber and friendlyname as well.
