A client asked me how to best install Windows 7 for testing. His son is interested in it, and he thought his son's machine could afford being wiped to install the new OS.
I instead told him to use VirtualPC to do the job.
A quick Google later, and I pointed him to these directions as they were as full featured and complete a set as I've seen... and I didn't have to type them myself. 🙂
Nice job, Abbas!
