The launch of Windows 7 has triggered at least a temporary spike in PC sales, Morgan Stanley analyst Katheryn Huberty says in an investment note issued yesterday. Pointing to NPD sales data, the researcher notes that computer sales jumped about 40 percent during the week of Microsoft's OS launch compared to the same time a year earlier. The number is partly offset by buyers holding off on purchases during the previous two weeks, when sales dropped 29 percent and then 2 percent versus 2008, but is well above earlier weeks, when sales were up by at most 19 percent.
