It's high season for consumer electronics. Manufacturers of various gadgets are unveiling their holiday lineups. Add to that products surrounding a new version of Windows coming out next month.

Here's a recap of the announcements so far:

— Tuesday: Microsoft Corp. releases the first major update to its server operating system since 2009, a prelude to releasing Windows 8 to consumers in October. Microsoft says Windows Server 2012 adds features that make it easier to manage large clusters of servers in data centers remotely.

— Wednesday: Nokia Corp. unveils its first phones running the next version of Windows. The company didn't reveal prices and says only that the Windows Phone 8 devices will be available in the fourth quarter "in select markets." The two devices are under Nokia's Lumia brand.

Motorola Mobility, under new owner Google Inc., announces three smartphones borrowing the Razr brand, the name of the hit clamshell phone from 2004. The $99 Razr M is to be in Verizon Wireless stores in a week. Two higher-end models will come later.

— Thursday: Amazon.com Inc. announces four new Kindle Fire tablet computers as it steps up competition with Apple Inc. and its iPad. Two of the models have screens nearly as large as the iPad's, at lower prices. Those will start shipping in November, while the smaller, 7-inch models will start selling next week. Amazon also refreshes its line of stand-alone e-readers.
