VHD Attach review
A focused, free Windows tool for mounting VHD, VHDX, and ISO files.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
VHD Attach is a Windows desktop utility for attaching, detaching, and auto-mounting virtual disk files. It is aimed at people who work with VHD or VHDX files and want file-level commands, startup attachment, or read-only access without relying on a broader virtualization platform. The utility can also display virtual disk information without attaching the file and supports ISO image mounting. Its documented operating-system support covers Windows 7, Windows Server 2008 R2, and later systems, while ISO and VHDX mounting are available on Windows 8 and later.
The pricing model is straightforward: VHD Attach is free and open source, with an MIT license reference. The published product information describes no paid tiers or feature-gated plans. That makes it suitable for users seeking a focused utility without a commercial subscription. Its feature set includes context-menu integration, a configurable auto-mount service, command-line attach and detach operations, and full-access or read-only attachment modes. These options give both everyday desktop users and command-line workflows a clear path for managing supported images.
Its main trade-off is scope. VHD Attach is designed for Windows and concentrates on VHD, VHDX, and ISO mounting rather than presenting a broader virtual-drive ecosystem. Users who need other image formats, write-image support, or a tool for non-Windows platforms should choose an alternative. For Windows users whose work centers on supported virtual disk files, the combination of startup automounting, persistent mounts, context-menu actions, and read-only controls makes VHD Attach a practical fit; those with wider format or platform requirements should look elsewhere.
