Unofficial script lets you install unreleased Windows 11 features without Microsoft Account

OfflineInsiderEnroll enables Windows Insider builds without Microsoft accounts via relevant Registry tweaks.

Microsoft has been steadily evolving the Windows Insider Program over the years, introducing new channels and testing paths that allow enthusiasts to experience upcoming and yet-to-be-released Windows features (some interesting hidden ones too) before they reach the public.

However, one long-standing requirement has remained largely unchanged as users are generally expected to enroll in the Program and with a Microsoft account. That's where a third-party tool called "OfflineInsiderEnroll" can help.

OfflineInsiderEnroll is said to be a lightweight script that enables access to Windows Insider Program builds on systems that are not signed in with a Microsoft account. Essentially the tool configures the necessary Insider settings locally and hence allows users to select and switch between available preview channels while continuing to receive builds through the normal Windows Update channel.

If you are wondering how it manages to do so, it is made possible by a Registry value known as TestFlags. When configured to"0x20", Windows stops communicating with Microsoft's online Insider enrollment services thus preventing locally configured Insider settings from being overwritten. This allows the script to apply its own channel configuration directly through the Registry as Windows Update does not verify whether a device has been officially enrolled in the Insider Program or not.

Previously the utility has had already supported the traditional Insider branches including Dev, Beta, and Release Preview. However following Microsoft’s recent restructuring of its preview channels, the script has now been updated. The latest OfflineInsiderEnroll version, 2.6.6, adds support for the newly introduced Insider channel lineup. As such, users can now choose from several Experimental channels in addition to Beta and Release Preview options. The update also retains tools for refreshing the Insider cache, resetting Insider settings, and completely stopping Insider enrollment when needed. Keep in mind though that will need elevated privileges when running the script (run as Admin).

You can get the latest version of OfflineInsiderEnroll from this page on its official GitHub repo.
