Windows Vista Licenses
Ed Bott from ZDNet clarifies the confusion regarding Windows Vista Licenses but the news is not as good as he suggests.
The Vista license marks the first time Microsoft has explicitly addressed the issue of virtual hardware in a consumer-oriented product, I believe. The current license for Windows XP makes no distinction between physical and virtual hardware
Vista Ultimate is different: The Vista license marks the first time Microsoft has explicitly addressed the issue of virtual hardware in a consumer-oriented product, I believe. The current license for Windows XP makes no distinction between physical and virtual hardware.
Bott concludes the change is best for tech savy users. Enthusiasts will disagree in that the restriction on licenses limits creativity.
