Yesterday, Microsoft released a brand new cumulative update for Windows 10, this time exclusively for computers running Threshold 2, but just as it happened several times before, this new version fails to install on quite a lot of computers.
While some claim that they see no error other than the usual “We couldn’t complete the updates, undoing changes” message, a number of readers confirm that the process fails to install with error code 0x80070570 and a text reading, “Some update files are missing or have problems. We'll try to download the update again later. Error code: (0x80070570).”
And unfortunately, Microsoft is yet to come up with a fix for this problem, so users are pretty much on their own if they really want to install the update (which they should, given the fact that it’s a cumulative update that includes bug fixes and performance improvements for Windows 10).
How to fix the issues
Fortunately, some of our readers have already come across a very simple way to repair the problem, and it only takes a few clicks to do it. Hat tips to our reader IAM for sending this in!
So basically, if installing the update fails for you too, here’s what you need to do.
First and foremost, go to the following path in your C: drive, where Windows is usually installed:
Look for a folder called like this:
And remove it completely (remember that you must be logged in with administrator rights to be able to delete it). Once you successfully delete this folder, launch Windows Update, check for updates once again and allow KB3116908 to start the install.
A reboot might be required if the update doesn’t show up in Windows Update, but in most of the cases, it’s available immediately once you delete the aforementioned folder.
And yes, it’s that easy!
