#Windows10 #PC – Why the latest Windows 10 cumulative update is failing and how you can recover : The latest cumulative update to Windows 10, KB3194496, is causing frustration for some PC owners, with the update trying and failing repeatedly to install. I’ve learned who’s most likely to be affected and also have two recovery options.
Those of us who routinely monitor Microsoft’s support forums knew last week that something was wrong with the latest cumulative update to Windows 10. We learned yesterday that Microsoft has now acknowledged the issue and is working on a fix.
The problem occurs with Cumulative Update KB3194496, which was released for Windows 10 version 1607 on Sept. 29, 2016.
For most users running the latest public release of Windows (version 1607, also known as the Anniversary Update), this cumulative update completes successfully and brings the current build number to 14393.222.
But if you’re one of the unlucky ones affected by this bug, after the required restart, the system reaches the “100 percent complete” mark and then announces: “We couldn’t complete the updates. Undoing changes.”
The whole process only takes a few minutes but it’s annoying. It’s also frustrating, because the update will try again the next day, only to fail again.
Fortunately, the issue appears to be limited to a relatively small subset of Windows 10 devices. You are at greatest risk if you have a machine that was previously part of the Windows Insider Program but was then removed from the program. The most likely time for this to happen was in late July or early August, after the release of the Anniversary Update.
And indeed, I encountered the failed update on two systems that matched that description to a T. Both had been part of the Windows Insider Program but were removed when the Release Preview build arrived and are now running the public (Current Branch) release, build 14393.
Microsoft says it’s working on a fix. Until that fix arrives, however, you can minimize frustration by doing one of two things.
Option one: Block the update temporarily.
To do that, download and run the Windows 10 “Show or hide updates” troubleshooter. In an ironic coincidence, I posted how-to instructions for this tool on the same day that the troublesome update was released.
The update, KB3073930, is available from this Microsoft webpage. Run the wizard, then choose Hide Updates, and select the KB3194496 update from this list.
