VHD Attach
What it is
VHD Attach is a free Windows utility for mounting and detaching virtual disk files. It adds Attach and Detach choices to the right-click menu for VHD files, and settings can add a Detach option to the hard-drive menu as well. The program can automatically attach disks when the system starts, with either full-access or read-only access, and can display virtual-disk information without mounting the disk. It supports Windows 7, Windows Server 2008 R2, and later, including Windows 10; older Windows versions such as Vista are not supported. On Windows 8 and Windows Server 8, it can also work with ISO images and VHDX disks. Command-line options include /attach, /detach, and /detachdrive. Its source repository is published under the MIT License. A VHD stored on a network location may need a service-account change to grant access. Automatic mounting of a BitLocker-enabled drive occurs before the user interface appears, so its password prompt is not shown.

The verdict
VHD Attach provides several ways to mount, detach, and inspect virtual disks on supported Windows versions. Check the network and BitLocker limitations if those situations apply.
Who it suits
VHD Attach suits Windows users who need context-menu or startup mounting for virtual disks. It may also suit users who want to inspect disk information without attaching a disk.
