A customer of mine located in Ajax needed to access his Windows XP desktop and work from his Windows 7 laptop.

He didn't want to use 2 computers and didn't want to have to migrate all of his software running on the XP computer over to his notebook.

Suggestion was to using Windows XP Mode on his laptop to access his XP computer.

This was accomplished by making an image of his computer that could be run on his laptop using Windows XP Mode (Microsoft Virtual PC)

To do this download the utility Disk2vhd to create an image of your current computer that can later be used by Microsoft Virtual PC or run on Windows 7 using XP mode.

The image of your hard drive will be created with a VHD file extension.
