A "not-well-advertised" fact about Windows 7 and VHDs (Virtual Hard Drives).

Have you ever created a VHD - and then wanted to access that drive from your Host machine - or even a completely different machine? Well now you can. OH! And even more importantly, if you have ever used the Windows 7 "Backup and Restore" to create a "System Image" - you can use this method to attach to the VHD that IT creates as well...

Microsoft created a TechNet article on how to both "create" and "attach" VHDs inside of Windows 7. You can view the article here: Create and Use a Virtual Hard Disk on Windows 7
