To get started with the Windows 12 beta, users must first register for the Windows Insider program and opt-in to receive beta builds. They will then need to download and install the latest build (2201) using the Windows Update mechanism or the Media Creation Tool.

As of now, there is no official Windows 12 beta version available. Microsoft has not announced any details about a forthcoming Windows 12 operating system, let alone a beta version.

Microsoft plans to release regular updates and beta builds for Windows 12, incorporating feedback from Insiders and addressing issues. The company aims to finalize the operating system by mid-2023, with a potential release date in the fall.
