What is Windows Insider Program

Windows Insider is an open software testing program by Microsoft that allows users who own a valid license of Windows 10[1][2] or Windows Server 2016[3][4] to register for pre-release builds of the operating system previously only accessible to software developers.[5]

Microsoft launched Windows Insider for developers, enterprise testers and the “technically able” to test out new developer features on pre-release software & builds, not given publicly released, to gather low level diagnostics feedback in order to identify, investigate, mitigate & improve the Windows 10 OS, with the help, support and guidance of the Insider Program Participants, in direct communication with Microsoft Engineers via a proprietary communication & diagnostic channel.

It was announced on September 30, 2014 along with Windows 10.[6] By September 2015, over 7 million people took part in the Windows Insider Program.[7] On February 12, 2015, Microsoft started to test out previews of Windows 10 Mobile.[8] Microsoft announced that the Windows Insider program would continue beyond the official release of Windows 10 for future updates.
