Win10 always reminds you that you can't update the uninstallation installation.

Make Windows 10 installation disk, backup data, format the hard disk, install the operating system … … these are as smooth as the flow of water, really make people feel comfortable, the anniversary update is also completed successfully. However, I never imagined that I was killed in the Windows 10 Version 1607 cumulative update (KB3194496)” on this patch, it will only appear in a few minutes, "Unable to update, the installation is being undone".

I wanted to ignore it, but the new problem came: after the installation failed, it will enter the "re-installation failure" in the endless loop, there is no solution. Others are watching the world outside, Xiaobian is tossing the computer at home, how sad it is!

The 7-day holiday, with 5 days and Microsoft's death, finally found the root of the problem. Is the ghost of the "XblGameSave" folder and its related registry items! Go directly to C:\\Windows\\System32\\Tasks\\Microsoft\\ and delete the “XblGameSave” folder completely.

Then we go to the registry editor, find the HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\WindowsNT\\CurrentVersion\\Schedule\\TaskCache\\Tree\\Microsoft\\XblGameSave item to delete the entire folder, and then install “KB3194496” There will be no more problems with the patch.
Hey, such a toss, the name of the registry enthusiast can be considered as a wash. In fact, think carefully, want to avoid the failure of Microsoft's official patch installation, must not be too deep optimization of the system, especially with third-party software key, assistants to clean up the registry and system files. Just like the many techniques introduced by enthusiasts, they are based on the tools of the system itself, closing some services, changing the registry, scheduling tasks, starting, and so on. No matter how you change it, it will not cause the system file to be missing, so that the new patch can't find the associated file during the installation process, or the wrong option is loaded. Third-party software, in order to achieve certain purposes, regardless of those, can use a one-size-fits-all approach will never go "think" why there is such a file in this place. Therefore, before using the third-party software toss the system, you must think twice, do not move things in the registry, Windows folder.
