Windows 7 is less of a resource-hog than Vista

Good news: The next version of Microsoft's Windows OS appears to be less of a resource hog than Windows Vista.
Microsoft had indicated previously that one of its design goals for Windows 7 is to give it the same system requirements as for Vista.
When Vista shipped it was seen as too resource hungry for the systems some customers were trying to run it on, resulting in sluggish performance. Indeed, Microsoft had to extend the life of Windows XP for small netbook computers because system makers said Vista would barely run on those devices at all.
