Windows 10: Unable to upgrade to Build 10166

I've had no problems upgrading to newer builds until now. The upgrade from Build 10162 to Build 10166 stops at 95% on the final install screen 82% on configuring settings, then goes back to Build 10162 when I restart. Any ideas? *Confused

:)

 

Unable to upgrade from build 10166 to build 10240

Thanks @Zigzag

But my copy will be activated after 29th right. Or do I have to downgrade then upgrade again?

 

Unable to upgrade from build 10166 to build 10240

I had installed Build 10240 but because of the WIFI issue I had to revert back to 10166. After I downgraded, I was unable to upgrade back to 10240 as it was not showing in the update. I reset my pc thinking some setting might be involved in preventing my
upgrade. Even after reset, the update did not show. Is there any way to get the update?

From today it started showing that my windows is not activated. Is there any way to resolve this issue?

 

Update 7/13: We’re only a couple of weeks away now from our public release of Windows 10, and we’re preparing for the world to begin the upgrade process. Windows Insiders have been the first to see our work on Windows 10 at every stage. Now you will also be the first to get a build flighted to you using the channels that we’ll use for targeting and deploying to PCs for our staged rollout.

We’re suspending the availability of Windows 10 builds briefly while we prepare for that, and the next build that we flight to you will be delivered using the production channels. Starting tomorrow, we will also not be delivering any additional ISOs at this point as we really need Insiders to be using, stressing, and validating our distribution and upgrade processes. We’ll make ISOs available again in the future, but for now we ask you to upgrade your current build via Windows Update once the next build is released.

Specifically, this means that in the next 24hrs:
•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 Home page - Windows Insider Program site and prerelease keys will no longer activate builds.

Once we have a new build available we’ll let you know through here with a blog post, Insider Hub, and on Twitter.

We’re very close to our public release and we’re working very hard to get everything just right. Please continue to send us problem reports using the Windows Feedback app for any problems that you encounter.
