Windows 7 has also pulled in more cash thus far, with 82% greater revenue than Vista. NPD notes that a combination of early discounts on presales and a lack of promotional activity for Windows 7 Ultimate caused the lopsided revenue. Windows 7 Home Premium Upgrade was the top selling SKU, with an average selling price of $76. Windows 7 Pro Upgrade followed in sales, with an average price of $147, and the $149 Windows 7 Home Premium Family Pack came in third place.
Microsoft's new operating system experienced a 40% boost in market share, and has noticeably increased PC hardware sales.
