Although Steven Sinofsky, the former president of Windows, and his team developed Windows 8 are highly confidential, multiple versions of Beta have been released during the development process, which allow interested IT and application developers access to early features and code, which is the embryonic form of the Windows Insider project.
The Windows 8 Beta version lasted until the official release of Windows 8.1 and was subsequently channelled by a more open form of public testing. This public test allows users and Windows engineers to communicate more smoothly, and then formally finalized as Windows 10 Insider Program.
