The current branch of Windows 10 Anniversary Update has more than a few lumps.
With Version 1607 installation failures, nearly weekly cumulative fixes, and problems with the Sept. 29 cumulative update, keeping AU up to date requires some careful steps.
Coping with frequent Win10-patching releases
More than a few Win10 users are having difficulty installing the Sept. 29 KB 3194496 release. In some cases, the update process fails, rolls back to the Sept. 20 update (KB 3193494), and then tries again the next day — all with repeated reboots.
In a few instances, the problem showed up on systems that had been set to receive Insider Preview builds and then reset to receive only the regular public updates. If you’re in that boat, you should wait for an official fix from Microsoft. On the other hand, if you never opted for the Insider test builds, I recommend choosing the simple solution below.
If you’ve been impacted by this Win10-updating debacle, here’s how to get out of it.
To prevent reboots due to patch failures, you can temporarily roll back the associated patch by following the instructions in MS Support page KB 3073930. While that information is about blocking problematic drivers, it’ll also let you temporarily block a pending update.
For example, if your computer keeps trying to install KB 3194496, the aforementioned support page has a download link for the “Show or hide updates” tool, which will list recent and pending updates and let you hide them — much as you hide unwanted updates in Win7. Keep in mind, however, that the tool only defers the update for a short time.
