Microsoft has reported that around one million people are trying out the Windows 10 Technical Preview and providing valuable feedback.
A blog post from Joe Belfiore, corporate vice president for Windows at Microsoft, said that the preview of Windows 10 has seen some 200,000 feedback notes described as "user-initiated".
"Over the weekend, we hit one million registrants for the Windows Insider Program. That equates to a lot of people using the Windows 10 Technical Preview and sending us feedback," he said.
"How much feedback? Over 200,000 pieces of user-initiated feedback have been submitted to us via the Windows Feedback app from Windows Insiders like you.
"This showcases how helpful it is for you to click the 'me too' button when you see someone else's feedback that you agree with or are experiencing yourself."
Users are doing more than just testing the software, Belfiore added. Some 36 percent have installed it on a virtual machine since the Windows 10 preview became available two weeks ago, while the remainder have it on PCs.
He said that these numbers made him "confident" that the firm is getting feedback based on actual usage as opposed to just a few minutes' experience.
Much of the feedback will come from so-called Windows Insiders, who actively subscribe to Microsoft. The firm is offering a new suggestion box on its pages for more casual commentators.
Meanwhile, Microsoft's Windows teams are crunching the feedback and the numbers and "cycling it back [into] development", according to Belfiore.
Microsoft released the Technical Preview on 1 October.
