Windows 10 Build 9879 Gets KB3020114 Update to Fix Explorer Crashes

Following the release of Windows 10 build 9879, Microsoft has released another update today that should fix Explorer.exe crashes in the Technical Preview.

Just a few weeks after the initial release of Windows 10 build 9879, Microsoft has released another path for it today that should fix, what many say is the biggest bug, which is Explorer.exe crashes.

Windows 10 Update December

KB3020114 for Windows 10 Build 9879

According to the Microsoft Support page, the updated fixes:

The Explorer.exe process continuously crashes and restarts after you upgrade to Windows Server Technical Preview or Windows 10 Technical Preview.

If you’re in the Windows Insider program, which we’ve explained how to join in this article, you can grab this latest patch from Windows Update now.

And yes, a restart of your system is required after installing it.

I was able to install it on my test laptop system this evening without any problem.

Did the update install successfully for you? I have been reading around that not everyone is able to get it to install out of the gate, and needed to do some reboots and other use workarounds to get it to install correctly.

Either way, leave a comment and tell us how it went for you, and if you’ve noticed any issues with your system since installing the update.

    Getting a message in the screen; One Drive is not available at this time, try again later. I press the only option at bottom which is cancel, it than gives me the regular color screens as if to finish the install cycle. After about 2 minutes, a dark screen with just the recycle bin and long error message saying it cannot find the profile-not available. I reboot, and it all happens again al over.
