Thank you, Satya, and good afternoon, everyone. This quarter, revenue was $22.1 billion, up 2% and up 5% in constant currency. Gross margin declined slightly, but was up 4% in constant currency. We grew operating income this quarter by 1% and 10% in constant currency, and earnings per share was $0.62, flat year-over-year and up 10% in constant currency. Our effective tax rate was 24%, higher than we anticipated, which impacted our EPS.
From a geographic perspective, our performance in most markets was as anticipated. However, Latin America, the Middle East and Africa were more unfavorable than we expected. In our commercial business, we continued to see healthy fundamentals, which led to a solid quarter of results. Commercial bookings increased 7%, up 9% in constant currency. Our total commercial annuity business had double-digit revenue growth in constant currency, and commercial annuity mix reached 86%, up 4 points year-over-year.
Commercial unearned revenue grew to just under $18.8 billion, up 3% and 8% in constant currency, slightly below expectations due to a higher mix of contracts with more in-period recognition and some deal weakness in the geographic markets mentioned earlier.
Our contracted not billed balance again exceeded $25 billion. Most important, as Satya mentioned earlier, our commercial cloud annualized revenue run rate surpassed $10 billion. This quarter, more than 65% of customers who signed enterprise agreements attached our commercial cloud offers, up 15 points from last year.
Our customers continue to make long-term commitments based on our compelling road map. Our commercial cloud gross margin was 45% this quarter, declining year-over-year. This decrease was driven by a higher mix of Azure revenue, our ongoing investment in data center capacity and geographic expansion and the small FX headwind.
As I mentioned last quarter, even as we are focused on gross margin improvement within each of our key cloud services, our total commercial cloud gross margin will reflect the dynamics of changing revenue mix and targeted investment.
In Q3, the FX impact of 3 points on year-over-year revenue growth was generally in line with the guidance, as the recent weakening in the U.S. dollar created less than 1 point of impact overall and across segments. As Chris explained earlier, we're not able to provide constant currency impact at the segment level for operating expenses and therefore segment operating income. In general, FX had a favorable impact of 1 point on operating expenses at the total company level.
As expected, our company gross margin percentage declined this quarter, driven by our accelerating mix of cloud services and our Intelligent Cloud and Productivity and Business Processes segment, offset by higher gross margin percentage performance from products within More Personal Computing.
Now to our segment results. This quarter, our Productivity and Business Processes segment delivered in line with our expectations, with $6.5 billion in revenue, increasing 1% and 6% in constant currency, with higher annuity mix, offsetting lower transactional weakness results due to a weaker PC market.
In Office commercial, revenue was flat and grew 7% in constant currency, driven by continued momentum in Office 365 with installed base growth across Office, Exchange, SharePoint and Skype workload. Our channel again expanded this quarter as more than 85,000 transacting partners sold Office 365 to small business customers.
Office consumer revenue increased 3% and 6% in constant currency due to an increasing base of subscribers and recurring subscription revenue. And our Dynamics business grew 4%, up 9% in constant currency. We more than doubled CRM Online seats for the sixth consecutive quarter.
Segment gross margin dollars declined 4%, up 1% in constant currency. As we've discussed, gross margin percentage declined on a higher cloud services revenue mix within the segment. Operating expenses decreased 1% even as we continued engineering investments in our Office 365 and Dynamics businesses and prioritized spend in growth areas like E5, security and voice capabilities. As a result, operating income declined 7%.
The Intelligent Cloud segment delivered $6.1 billion in revenue, which grew 3% and 8% in constant currency, just at the low end of our guidance range. Our total server products and cloud services revenue was flat year-over-year and increased 5% in constant currency. Against the prior year comparable, we had 16% constant currency growth.
This quarter, our enterprise server customers continued their commitment to our hybrid cloud platform offerings, which resulted in double-digit annuity revenue growth in constant currency, including over 100% growth in Azure. That growth was partially offset by a larger-than-expected decline in our transactional on-premise server business, which impacted the in-quarter results. Enterprise services continued to perform well, with 11% revenue growth or 15% in constant currency, driven by customer demand for our support services and solutions.
Gross margin declined 2% and grew 3% in constant currency. Gross margin percentage declined as cloud mix accelerated, offsetting margin improvements in Azure and Enterprise services. In response to enterprise customer demand and to increase our share in the cloud market, we grew operating expenses by 13% through Azure-focused investments across engineering, additional sales and marketing capacity and the acquisition of Xamarin. This quarter, operating income declined 14%.
Now to our final segment, More Personal Computing. Revenue exceeded our expectations at $9.5 billion, up 1% and 3% in constant currency. First, our OEM results. Our total OEM business declined 2% this quarter, outperforming the overall PC market, which was weaker than we expected. OEM non-Pro revenue increased 15%, driven primarily by a higher-than-expected mix of premium devices. OEM Pro revenue underperformed the commercial PC market, declining 11% due to the higher inventory level in Q2 that I mentioned in my last earnings commentary.
Windows volume licensing grew 6% in constant currency, and IP licensing continued to decline, impacted by both a decrease in total unit volume and a higher mix of lower royalty units. As expected, devices revenue decreased this quarter. Revenue declined 11% or 9% in constant currency, primarily due to phone. Revenue declined 46% in constant currency.
Additionally, sell-through of our Lumia products was weak, and we exited the quarter with relatively high channel inventory. As Satya mentioned, momentum in our Surface business continued as revenue increased 56% or 61% in constant currency with strong commercial and consumer demand for our service lineup. Overall, device gross margin dollars grew and gross margin percentage improved, primarily driven by a shift to our higher gross margin Surface portfolio.
Our search business remained strong this quarter, with growth driven by higher revenue per search and higher search volume. We again had U.S. PC share growth and search continued to be profitable.
In gaming, revenue grew 4% or 6% in constant currency, with continued progress in the monetization of our installed base. We saw higher revenue from Xbox LIVE, driven by both higher volumes of transaction and higher revenue per transaction as well as an increase in revenue from our gaming studios. As expected, Xbox hardware revenue declined, mainly driven by lower Xbox 360 consoles sold and lower Xbox One pricing.
Segment gross margin increased 2% or 6% in constant currency, driven primarily by gross margin percentage improvements in devices and gaming. Operating expenses decreased 14%, primarily through our actions in phone and the transition of our display business to AOL. As a result, segment operating income grew 57%.
Now back to our overall company results. As planned, we accelerated our data center and cloud services investments to meet growing global demand. This quarter, we invested $2.3 billion in total capital expenditures, including an increase of 65% year-over-year primarily for data centers and servers. Other income was negative $247 million, driven by interest expense and net losses on derivatives, partially offset by dividends, interest income and net recognized gains on investments.
Our non-GAAP effective tax rate was 24%, higher than we expected, which reflected the changing mix of revenue across geographies as well as an accelerating shift in revenue from software licensing to cloud services. The rate for the quarter included a catch-up adjustment from Q1 and Q2, reflecting the new full year -- the new expected full year non-GAAP effective tax rate. This quarter, we returned $6.4 billion to shareholders through share repurchases and dividends.
Now let's move to the outlook. First on FX. Consistent with our guidance last quarter, we still expect FX to negatively impact year-over-year growth in Q4 by 3 points. By segment, we expect 3 points of impact on Productivity and Business Processes, 3 points in Intelligent Cloud and 2 points in More Personal Computing.
Second, our commercial business. Our commercial business will be on pace for continued strong annuity growth as both new and existing enterprise customers adopt and use our growing portfolio of cloud services. Even with projections of tightening global IT spend and currency headwinds, we expect commercial unearned revenue to be $24.3 billion to $24.5 billion, in line with historic seasonality. We remain on track toward our $20 billion commercial cloud revenue run rate goal as we grow revenue, drive consumption and focus on gross margin improvement in Office 365, Azure and Dynamics Online.
Finally, we will continue our investment in data centers in capital equipment to address customer demand for our cloud services. With that, let me share our view by segment. In Productivity and Business Processes, we expect revenue to be $6.5 billion to $6.7 billion, with continued annuity shift to the cloud offsetting the impact of a weaker PC market on our transactional business and our consumer and commercial segments.
In Intelligent Cloud, we expect revenue between $6.5 billion and $6.7 billion, driven by annuity growth, offset by continued transactional weakness. In More Personal Computing, we expect revenue between $8.7 billion and $9 billion.
Here's a bit more detail on its individual components. In Windows, we expect our OEM Pro revenue to be largely in line with the commercial PC market. Our non-Pro revenue is expected to be above the consumer PC market, similar to what we saw in Q3, primarily due to continued benefit from a strong mix of premium devices. In devices, we anticipate continued momentum and growth for Surface Pro 4 and Surface Book, particularly with business customers. For phone, we expect year-over-year revenue declines to steepen in Q4 as we work through our Lumia channel position. In search, we will continue to show healthy revenue growth with full year profitability.
Finally, in gaming, we expect to see continued healthy user engagement on our Xbox platform and we look forward to E3, where we will announce new titles for the upcoming fiscal year. We expect COGS to be $7.8 billion to $7.9 billion, and we expect operating expenses between $8.2 billion and $8.3 billion. Our full year guidance is now down to $31 billion to $31.1 billion as we concentrate our investments in engineering and technical sales to accelerate our cloud growth heading into the next fiscal year.
We expect other income and expenses to be negative $200 million in Q4. This includes the net cost of hedging and interest expense, offset by dividend and interest income. For tax, based on trends reflected in this quarter's full year catch-up adjustment, we expect our Q4 effective tax rate to be 21% and 23%. We expect our full year effective tax rate to be between 20% and 21%.
Before I wrap up, I'd like to share a few directional comments on fiscal '17. This year, we saw strong growth in our commercial cloud portfolio, and we grew our annuity penetration across our commercial business. We anticipate those trends will continue next fiscal year, driving our revenue growth and impacting our gross margin percentages.
As we continue to unify and modernize our Windows installed base across our consumer and business customers, we will advance our progress and our postsale monetization scenarios and execute on the Windows 10 enterprise deployment opportunity.
Throughout fiscal '16, our significant investment in engineering, sales and marketing has positioned us to support our customers' digital transformation and to innovate in device form factors like Surface and HoloLens. In fiscal '17, we expect to continue that investment and reallocation process. Therefore, total operating expenses should be flat to up slightly. I look forward to sharing more on our FY '17 plans in July. With that, Chris, let's go to Q&A.
