Microsoft got a bigger boost in customer satisfaction from its latest computer operating system than rival Apple Inc. did from its most recent upgrade.
A study shows that respondents giving Microsoft a positive grade for satisfaction rose to 67 percent in the week after the Oct. 22 release of Windows 7, from 64 percent the day before it went on sale, according to YouGov Plc, a London-based market-research firm.
Microsoft’s satisfaction rates rose 14 percent through the end of the year.
Apple’s Aug. 28 release of its Snow Leopard software resulted in a boost of 1 point to 65 percent in the first week. Through the end of the year, the increase was 6.9 percent.
Microsoft’s Windows runs more than 90 percent of the world’s personal computers.
