Windows Division revenue increased, due mainly to the recognition of $1.1 billion of revenue related to the Windows Upgrade Offer. Revenue from Surface and increased commercial sales of Windows was offset by the impact on revenue of a decline in the x86 PC market. OEM revenue grew 17%, reflecting the revenue related to the Windows Upgrade Offer, offset in part by the impact on revenue of a decline in the x86 PC market.
Windows Division operating income increased, primarily due to revenue growth, offset in part by higher cost of revenue and sales and marketing expenses. Cost of revenue increased $306 million or 65%, reflecting product costs associated with Surface and Windows 8. Sales and marketing expenses increased $291 million or 43%, reflecting advertising costs associated with Windows 8 and Surface.
