I have 
 Windows 7 Starter Activation on my computer right now. It was pre-loaded on the 
 Windows 7 Starter 32bit. I'd like to upgrade it to 
 Windows 7 Home Premium 64bit. I am also planning on buying a Mac. Will I be able to load the 
 Windows 7 32bit version on that also? 
 Windows 7 Professional Product Key advance for your help.
