Found this great list of Windows 7 “secrets” via Shawn Wildermuth on twitter. I think my fave is between the Black Box Recorder (#7 on Tim Sneath’s list) or multi-monitor window management (#4), since I use three monitors on my primary machine (which is due for a Windows 7 install soon):

It’s great to see Windows 7 Beta finally released to the world! We're very proud of what has been accomplished over the last months; in many ways, it sets a new quality bar for a beta operating system release. Building on top of the Windows Vista foundation, Windows 7 adds a great deal of polish and refinement to both the user interface and the underlying architecture, while at the same time introducing many new features and improvements that support new hardware, give power users and casual users alike better tools to manage their digital lives, and enable new classes of application experience.

Over future blog entries, I’ll spend time drilling into some of those areas in more detail; of course, there are plenty of articles already out there that dissect Windows 7 in some depth, with the Windows SuperSite and Ars Technica providing notably comprehensive entries. I’d also like to draw particular attention to the series of Windows 7 interviews that Yochay Kiriaty has been posting on Channel 9, which give the inside scoop on the development of many of the most significant new features.

For now, though, I want to focus in on some of “secrets” of Windows 7: the many little tweaks and enhancements that we’ve made in this release that I’ve discovered and collated over the last few months of using Windows 7 across my home and work machines. These are the things that are too small to appear in any marketing document as “features”, but that you quickly miss when you switch to an older version of Windows. There are some who think that we’re arbitrarily hiding functionality to make Windows easy for casual users, but I’d argue that a great deal of effort has been put into this release to satisfy power users. In homage to those of us who enjoy discovering the nooks and crannies of a new operating system list, I’ve put together the longest blog post that I’ve ever written. If you’ve downloaded and installed Windows 7 Beta recently, I think you’ll enjoy this list of my thirty favorite secrets. Have fun!

There are 30 “secrets” in all, so you’ll want to read the whole thing.
