The Microsoft Windows Insider program allows company friends to try out upcoming Windows 10 features before releasing them to consumers.
To join the program you need a Microsoft account and of course a system with Windows 10. Unfortunately, if you do not have a Microsoft account you can not participate in the Windows Insider program.
To date, as a freelance developer has developed a script called 'Offline Insider Enroll'. This script allows Windows 10 PCs to participate in the Insider program without a Microsoft account.
According to release announcements on Github, the developer states that the script takes advantage of the "TestFlags" registry value to enroll a user in the program:
If this value is set to "0x20", online access to Windows Insider is disabled. So we can have Windows Insider, and because Windows Update does not check if the machine is actually registered to the program, it will provide you with Insiders updates.
The script installation process is quite easy and is performed entirely in the Command Prompt as described below.
Let's see how it works:
Download the script "Offline Insider Enroll" from GitHub and save it anywhere on your system.
Export the file to view OfflineInsiderEnroll.cmd.
To run the script, right-click on the file and select 'Run as Administrator'.
You will be asked to select the Ring you want to connect to. More information about the various rings you can find here.
After selecting the ring you are interested in, you will be prompted to restart your computer.
After rebooting the system, open the Windows Insider control panel in Settings and you will see that you have been added to the selected ring.
To stop running Windows Insider, you can run the script again, but this time select X and then restart your computer.
