Microsoft is releasing a mainstream operating system that was directly shaped by its most enthusiastic users. It also means that this OS was truly crowdsourced with 75 million pieces of feedback and 5,000+ enhancements to the OS attributable to volunteer Insiders (estimated to be slightly less than 10 million people). This free program means that customers can get early access to what eventually is the Anniversary Update.
Many of the changes, or at least the direction in which the changes went, were a direct result of the millions of Windows Insiders.
