With a market share that surpasses 16%, Microsoft's Windows Vista is crawling towards a goal it may never reach (surpass Windows XP's share) due o the release of Windows 7 in 2010. Despite this situation, Vista sales are growing and now Microsoft can brag with over 180 million Longhorn licenses being shipped and sold.

Windows Vista has had a rough start last year with Microsoft receiving a lot of criticism over how the OS was designed and how it turned out but time heals all wounds and 180 million sold units is somewhat proof of that.
