One million people have joined Microsoft's Windows Insider Program to test out the Technical Preview edition of the company's forthcoming Windows 10 release.
The milestone was reached about two weeks after the October 1 release of the Windows 10 Technical Preview, designed for more technically adept users to test and provide feedback to Microsoft.
And testers have been providing plenty of feedback, courtesy of Microsoft's near real-time telemetry system that's bundled with the release to accelerate the Windows development cycle.
According to ZDNet's Mary Jo Foley, the telemetry system,in tools used under the Xbox development process.
"Over 200,000 pieces of user-initiated feedback have been submitted to us via the Windows Feedback app from Windows Insiders like you," wrote Windows phone, tablet and PC design lead Jo Belfiore in a blogpost on Monday.
"People on the team are hard at work poring through all the feedback, categorising and processing it, and cycling it back into our development," he wrote.
According to Balfiore, a majority, or 64 percent, of the testers are running the Windows 10 Technical Preview on "actual PCs" rather than merely peeking at the release through a virtual machine.
The other indicator it believes it has "solid usage" that 68 percent of recruits are launching more than seven apps per day. A quarter of devices running the Windows 10 Technical Preview launch more than 26 apps per day, while five percent launched 68 apps per day.
Perhaps the bigger question is exactly what type of feedback Microsoft is getting from testers. Balfiore doesn't answer this directly, but points to a list published by Windows watcher Paul Thurrott based on popular requests for changes in the feedback to Microsoft thus far that were captured by a third-party.
The list includes a blend of sensible requests — such as the ability for the user to move or disable the new Search and/or Taskview buttons and adding tabs to File Explorer — as well as superficial ones, such as adding an animation when the opening the Start Menu.
