Windows 7: Five security lessons learned from Office 2010.

The upcoming version of Microsoft’s productivity suite rethinks how desktop applications should approach security.
I continue to be impressed with the changes coming in Office 2010 (currently in beta). Previously, I explained how Microsoft drew on real-world usage data to craft the beta suite's updated UI. Security is another priority for the upcoming release, and while the improvements there aren't as readily apparent, for developers they're equally noteworthy.
The Office suite is complex and feature-rich, making it a ripe target for malware and other security exploits. Given its vast and diverse user base, however, for Microsoft to remove existing features in the name of security would be out of the question.
