NoteUPDATE: Upcoming changes to Windows 10 Insider Preview builds
Getting the final release on July 29th
Windows Insiders running the Windows 10 Insider Preview (Home and Pro editions) with their registered MSA connected to their PC will receive the final release build of Windows 10 starting on July 29th. This will come as just another flight. I’ve gotten a lot of questions from Windows Insiders about how this will work if they clean installed from ISO. As long as you are running an Insider Preview build and connected with the MSA you used to register, you will receive the Windows 10 final release build and remain activated. Once you have successfully installed this build and activated, you will also be able to clean install on that PC from final media if you want to start over fresh.
If you are running the Enterprise edition of the Windows 10 Insider Preview, to upgrade to the final release of Windows 10 Enterprise you will need to download and activate it from Volume Licensing Service Center. As a reminder, the Enterprise edition of the Windows 10 Insider Preview is not eligible for the free upgrade offer and can be upgraded to the final release of Windows 10 through an active Software Assurance agreement.
