Microsoft has revealed that Windows 7 will feature a number of functions developed for enterprises, which are the result of feedback from customers.

The features have been included following a review of feedback from 100 customers and partners, which the company implemented after learning from mistakes it made when building Vista, said Gavriella Schuster, a senior director of Windows product management.

Microsoft developed four new customer and partner focus groups and spent six months planning how it would build Windows 7, and how it would engage customers early and often in that process, before even beginning development, she said.

In addition to expanding the number of testers in its existing Technology Adoption Program from about a dozen to nearly 20, Microsoft formed a Desktop Advisory Council, an original equipment manufacturer (OEM) engagement group, a Windows ecosystem readiness program and a First Wave program of customers to deploy the beta in live environments to garner "really early insight" from customers and partners about what the final OS should look like, Schuster said.

The company invited 4,000 enterprise customers in the US, Germany, Brazil, Japan, India and China to provide feedback as part of extensive research as well, she said.

Enacting this unprecedented level of early customer engagement, combined with an effort to make the development process more predictable in general, were aimed at avoiding missteps the company took as it built Vista. Features Microsoft promised early on in Vista's development didn't make it into the final code, and the process itself was shut down and restarted midway through.

"We know the stop-and-start nature of Vista [development] posed a lot of challenges for customers," Schuster said.

With Windows 7, Microsoft has tried to share information "only when we had a higher degree of certainty" Microsoft could deliver on features or time frames for release milestones, she said.

As a result of all of this effort, Windows 7 will include several enterprise-specific features developed based on feedback from Microsoft's focus groups and other research.

Customers and partners said that protecting corporate data was a key priority, which is why Windows 7 will expand the BitLocker feature from Vista with a BitLocker To Go feature, Schuster said.

BitLocker To Go will extend the encryption already provided by the feature not only to the PC's hard drive itself but to any external USB device that is plugged into the laptop, she said. This will make it more difficult for hackers to access data not only on the PC but on peripherals connected to it.
