Microsoft has posted on their Facebook page that they now have over 2.2 million users which means that in the past eight days, they have added over 500k new testers of Windows 10



From Neowin:

At Microsoft's Windows 10 keynote last week, they announced that there were 1.7 million Windows 10 beta testers, or as the company calls them, Windows Insiders. A few days later, during the company's earnings call, they said that there were 2 million Windows Insiders and now, the company has announced that they have passed 2.2 million beta testers.

The information was posted up on the company's Facebook page this morning and puts some meat behind the Windows 10 hype and shows that consumers are quickly warming up to the new OS that Microsoft will release later this year.
