Description: This article describes how to mount a virtual hard drive (VHD) in Windows 7.

1. VHD is a file extension in Windows that stands for Virtual Hard Disk. It is a publicly available image format specification that allows the encapsulation of an entire hard disk in one file. It is capable of hosting several formats such as NTFS, FAT, exFAT and UDFS and may be used as a boot drive by programs such as Microsoft's Virtual PC. One may wish to access the contents of a virtual hard drive without actually booting it up. This is natively possible in Windows 7 by mounting the image to appear as another hard drive.
