[H] Windows XP Mode

[Winterlight]

I run Windows 7 PRO 64bit which means I am entitled to download a 
free Windows XP to use with Virtual PC. I have never tried MS Virtual 
PC. I have loved and use VMware for many years... version 7 now. 
However, it is a free XP license which I would like to have for a 
virtual machine.  Is there any reason I wouldn't want to do this? I 
wonder if I can use the license on a VMware virtual pc.
