Microsoft is taking over San Francisco's Moscone Center today to introduce a preview version of Windows 8.1. Although the company has revealed most of the features in the upcoming update to Windows 8, I’ve had a chance to get well acquainted with the Windows 8.1 preview to learn more about the changes involved.

In my previous look at 8.1 I summarized that the preview brings many small tweaks that make for a significant update, and that still stands. Microsoft is pushing a new search experience alongside UI tweaks, new and improved apps, and some better customization options for regular and power users alike. Let's dig in.

For even more on 8.1, check out our in-depth preview from last month.
