According to the techcrunch.com, Microsoft said in a blog post that there are five million Windows Insiders, up from 3.7 million in May.
The company also said that it has collected millions of reservations for Windows 10 from the public.
Microsoft will give Windows 10 as a free upgrade to Windows 7 and Windows 8 and 8.1 users for a year.
If the user is a current Windows 10 tester, he or she will get the build first among the public.
Terry Myerson, Microsoft's Number Two, said that starting on July 29, they will start rolling out Windows 10 to their Windows Insiders. From there, they will start notifying reserved systems in waves, slowly scaling up after July 29. Each day of the roll-out they will learn and update the experience for all Windows 10 users.
Myerson also said that they will distribute a build of Windows 10 to retailers all over the world so that they can assist their customers with upgrades of newly purchased devices.
Volume license customers can snag Windows 10 on August 1.
In its post, Microsoft stressed that it is working to make sure that all systems can upgrade and that it won't move people to Windows 10 until it should work with their setup.
