Windows 10 build 14366 won’t load, Insiders report it fails on the last reboot

2 minute read

Windows 10 build 14366 is here, but not all Insiders have managed to fully install it. For some Insiders, the build failed on the last reboot, leaving them unable to test out the latest bug fixes and system improvements brought by this build.

So far, only three users reported this issue on Microsoft’s forum, but the thread has more than 40 views and we suspect the real number of impacted users is much higher. This is not the first time when Insiders encounter similar issues, as many will remember that build 14332 also caused installation fails, among other issues.

Interestingly enough, Microsoft’s Support Team haven’t reacted in any way to this thread, and they haven’t even tried to offer a copy-paste solution to this problem. Let us hope that someone saw this thread and at least escalated it, if there is no known solution for the time being.

On the other hand, Insiders who did manage to install and load build 14366 have encountered issues of their own. Many reported they couldn’t access the Start menu, the Settings App or OneDrive because of the “Class Not Registered” error. Fortunately for them, there is a fix available for this issue.

It appears this is one of the recurrent build errors, as users encountered it in previous builds and we managed to find several fix methods for it.

Build 14366 didn’t bring only negative elements, it also brought a very useful Windows Store update addressing crash bugs. Update 11606.1000.43 allegedly kills off all the crash bugs that prevent users from downloading a particular app or simply browsing content.
