3.7 million people have signed up to try Windows 10 via the Windows Insider program

Microsoft has announced during a presentation at Build 2015 that 3.7 million people have signed up for its Windows Insider Program to try out preview builds of Windows 10 for the PC and smartphone.

This is yet another big increase in the number of people who have signed up to participate in the program. In late January, Microsoft said there were 2.2 million Windows Insider members, and earlier in that month the company said there were 1.7 million members.

On Thursday at Build, we learned that the Windows Insider program will continue even after Windows 10 reaches its RTM status, with Microsoft wanting to test new features and patches for the OS with those members before they are released to the public. The program could also add more update rings in addition to the "Fast" and "Slow" rings that are currently available, and that might include a "ludicrous" ring that will send out updates to Windows 10 on a daily basis.
