OfflineInsiderEnroll

The Windows Insider program allows regular users to experience the latest Windows functions and actively contribute to the shaping of the upcoming versions of the operating system. However, a Microsoft account is required to join the program and there is no way to go around this setting, at least until you stumble upon the OfflineInsiderEnroll script.

OfflineInsiderEnroll was created to allow computer users to join the Windows Insider program even if they choose not to create a Microsoft account. Prior to moving on and running the script, please be advised that joining the Windows Insider program means that your computer will test the upcoming features of Windows, with all the risks involved. That is why it is recommended not to join the program on your day-to-day PC, but use a virtual machine instead.

OfflineInsiderEnroll is delivered to you inside a simple archive, but note that administrator privileges are mandatory to run the script. A console window is opened, which displays a list of all the channels you can enroll with in the Windows Insider program: the Dev channel, the Beta channel and the Release Preview channel. Obviously, the latest is the safest, while the Dev channel is the one where new features are first released for testing.

You might wonder how this script can bypass Microsoft’s filter for logged-in users. Well, the script takes advantage of the undocumented TestFlags registry value on Windows 10 RS5 and later. Should Microsoft decide to close this loophole in the future, the application might fail to work.

If you decided the channel to enroll, it is time to reboot Windows to apply the changes. A restart is required to activate the Microsoft Flight Signing, a mandatory feature for the Insider program.

To restore your computer to “normal” and not receive updates from the Insider program anymore, simply run the script again with administrative privileges and choose to “Stop receiving Windows Insider builds”.

The OfflineInsiderEnroll script exploits a loophole in the Windows 10 registry to allow joining the Insider Preview program without signing in with a Microsoft account. This is a nice tweak if you want to test the latest Windows functionality.
