VHD Attach was created to scratch my itch when it comes to working with virtual disks. As things go, that also meant that some corners were cut. As application went freeware, much of those corners were fixed. One that remained was DISKPART.
You see, attaching was done via API, but detaching of drive was done from command line via DISKPART and then results were parsed. This particular operation was very prone to error when it comes to localized versions of Windows. I will not even get into performance issues with it - let's just say that DISKPART is not quickest program to initialize.
This version of VHD Attach finally replaces DISKPART with direct usage of Virtual Disk Service and thus it should handle LIP more gracefully (although program remains English-only).
Without further ado, download is available here.
