Virtual PC is like having a virtual computer. It runs on a virtual harddrive on your main harddrive. You can set up a shared folder to share files beween your main OS and the virtual one.

With Virtual PC you can run one or even multiple other operating systems from your Windows XP or Windows Vista. Here we're interested in running Windows XP that fullfills the requirements of Fairuse4wm as a virtual OS.

In this virtual OS you log in onto your media content provider's web-site and download DRM protected files. Then use Fairuse4wm to remove DRM protection and put the unDRMed files into shared folder. You will immediately get access to the DRM-free files from your main OS.

It's much easier compared to having one more copy of Windows XP on your PC, 'coz you don't have to reboot and boot under different OS each time you wanna use another OS. You just run Virtual PC or WM Ware, hit the play button on the virtual OS to run it. Then use it as long as you need, then stop it and you're again in the main OS. It's like a snap!

Just don't update your virtual Windows XP. Or at least make sure to apply updates selectively.
