Yesterday, Microsoft released a new service pack update for Windows 10. The update, dubbed KB3140741, is only available for users who have the Threshold 2 update (1511 version) installed on their Windows 10 computers.

This is just a minor patch to the system as it only brings some stability improvements and enhancements, and Microsoft not even providing detailed information about the update. The update also doesn’t appear on Microsoft’s Update History page, so we assume it’s very tiny. To install the KB3140741 patch, head over to Settings > Update & security and check for updates. All users running the 1511 version of Windows 10 should have already received this update.

One interesting thing about the announcement of the update is that Microsoft provided details regarding the size of the update, which isn’t usual practice:

“This update makes stability improvements for Windows 10 Version 1511 servicing stack.
If you are installing a servicing stack update package for the first time, the package for the x86 version is 5 MB and the package for the x64 version is 11MB.”

This update is not a cumulative one as some users might think. This is just an ordinary patch for the system and it doesn’t contain fixes, improvements, and features of previous updates. (In case you’re not familiar with how cumulative updates work, here’s a quick reminder: a cumulative update contains all features and improvements from a previous cumulative update, so even if you missed installing one cumulative update, you’ll receive everything from the pack with the next one.)

Since this is just a minor update, it shouldn’t noticeably affect your system, therefore you shouldn’t encounter any issues. If you do, please let us know in the comments, and we’ll try to find a solution for your problem.

  • KB3140741 will not complete the install. It tries each time the system is restarted. It runs for about 40 minutes them the machine shuts down, To restart I need to disconnect the power then power back up. There is no way to delete the patch that I have found.

  • It seemd like I am just not able to use windows right now. No right click working on task bar. No start Menu. Neither able to login into windows account..

  • Every day, because of the Windows 10 updates, I lose the functionality of (a) having right clicks on the taskbar; (b) having jump lists from the task bar (c) having a start menu. Therefore I am required to run, from the Power Shell (admin) command prompt, this: Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppXManifest.xml”}
    Every single day.
    If that doesn’t work, then I must also restart from msconfig in Safe boot with Network, and then restart again back into normal mode. I am tired of wasting time doing this every single day, sometimes twice a day. Why is it that Microsoft still has not fixed this, nor offered a fix for this? If anyone knows where to obtain a fix for this incredible annoyance and interference with our computers, which renders them nearly unusable unless we go through this process, please, please share this with us.
    In addition by the way, I have reinstalled Windows 10 a dozen times in hopes that the latest installation would fix this. Each of these procedures takes hours of my time, but within a short while, the problem returns, and I have to repeat them.
    Thanks for any help you can offer, out there.
