With the release of Windows 10 on July 29th nearing, Microsoft is making some changes to the Insider program in order to make sure all aspects of the release run as smoothly as possible.
Microsoft's Gabe Aul has updated the blog post issued for the release of Build 10166 announcing that, along with the next build, Microsoft will also be testing the specific production channels by which consumers will be receiving Windows 10 when it launches. He also provided specifics on the other changes that will occur in the next 24 hours.
- Builds 10162 and 10166 will no longer be offered over Windows Update, and whatever build you’re on will show as “up to date” if you check for new builds.
- ISOs for build 10162 will be taken down from the https://insider.windows.com site and prerelease keys will no longer activate builds.
If you were planning to use an ISO for a fresh install, you will want to move fast. ISOs will return to the Insider Program after Microsoft release Windows 10, but for now they want to encouraging users to utilize Windows Update to aid them in identifying any bugs in the update process.
Microsoft hasn't provided any clues on when we might get the next build, but the latest preparations, and number of builds making it successfully through their internal rings, suggest it may not be far off.
