Windows 10 KB3213986 reported issues

KB3213986 download gets stuck

The classic download and install issues also affect Microsoft’s latest Windows 10 cumulative update. Users report that KB3213986’s download progress gets stuck at certain percentages for hours on end. It appears that patience is a virtue on Patch Tuesday: The update will eventually install, but the whole download and install process may last for more than three hours for some users.

Since I started the Windows update about 2 hours ago, to download today’s January 2017 patch Tuesday updates to my computer, the progress has been stuck on KB3213986 at 78% for almost 2 hours now

KB3213986 won’t detect battery

Windows 10 users also report that KB3213986 won’t detect battery. When users unplug the laptop, the OS displays a message informing them that the battery’s remaining time is unknown.

So I updated today Windows 10 (KB3213986), and now my battery either displays an empty Icon saying “Unknown remaining” or “No battery is detected”. BIOS is up to date as well. Anyone else has this issue? Any idea how to solve it?
The battery still works when the laptop is unplugged but it shows the “unknown remaining”.

Apps are full-screen

Update KB3213986 resets the system into tablet mode. As a result, all apps appear full-screen, leaving users unable to adjust app window size using regular methods. To fix this issues, simply disable tablet mode and everything should be back to normal.

I have just installed updates, above is my info. I have a problem that everything, mail, games apps etc are all full screen size. No option top right to reduce.  How can I get these to adjust app size?

As you can see, KB3213986 is a stable update and doesn’t cause major issues on Windows 10 computers. If you’ve come across other bugs, tell us more about your experience in the comment section below.
