Instead, the build was privately circulated until it was eventually uploaded to the BetaArchive FTP server on November 24, 2019. Because it was designed to run on the same hardware architecture as the defunct Windows RT and Windows 10 Mobile, the enthusiast community quickly realized its potential as an unofficial upgrade path for abandoned devices.

However, during an internal Microsoft security breach in early 2017, an unreleased compiled explicitly for ARMv7 surfaced. The build leaked publicly to the BetaArchive platform on November 24, 2019. The Limitations of the Raw Build

Every pre-release build has an expiration date. Build 15035 was set to expire in mid-2017. The Media Builder included a script that either extended the expiration by 10 years or removed the license polling mechanism entirely. This turned a temporary beta into a permanent OS.

To understand why the Media Builder exists, it is essential to look at the history of Windows RT. Launched in 2012, Windows RT was Microsoft’s first major attempt to run Windows on ARM architecture.
