That’s right! Windows Vista can run using a total of zero system memory. Well, bear with me, it will all make sense in the end. When it first introduced Windows Vista, Microsoft faced criticism because of the system requirements associated with the new platform. And the truth of the matter is that Vista is nothing short of a resource hog. The latest operating system from the Redmond company will eat right through CPU cycles, and will swallow every last bit of Random Access Memory you can throw at it. Vista will hesitate little to consume all the resources at its disposal in order to deliver the high-end performance level and user experience synonymous with the Wow.
