  1. After Windows Update automatically installed August 23, 2016 — KB3176936 and KB3176934 (OS Build 14393.82) (Windows 10 version 1607) my Weather app live tile stopped updating.

    I could click the app and it would open fine with the current weather data, but the large Weather live tile would not update. After turning off the live tile then back on, I would only get the default app icon image, no data at all (even though opening the app shows changes to data from the last check) even after PC reboots!

    I performed a System Restore to before KB3176936 and KB3176934 and the live tile came back as normal. This is repeatable.

    I have since disabled Windows Update service completely due to multiple issues with this service making automatic changes causing multiple problems: installing malfunctioning display drivers for a Nvidia GeForce GTX 770, live tiles not working, and random CPU 100% usage in the middle of important work by Windows Modules Installer Worker.

    • If Weather app live tile is not working, uninstall it. Restart your computer and download fresh copy from Windows Store. Please note that all MSN apps have this issue. About CPU 100% usage, always check which application is using most CPU power via Task Manager. I think it should be Anti-virus software.

  2. It wont install for me, I tried it through Windows Update and standalone msi.

    Initial install goes fine, however after pressing restart it applies 30% of the update and restarts to finish updating. Then when the laptop boots the update gets to 99% and says Update Failed – Undoing Changes. I’m stuck, tried troubleshooting windows update and that didint help.

    I have a password set in my Premamod bios so when laptop is turned on or rebooted I have to type password in at BIOS post before Windows starts booting. I’m sure that isnt interfering with Windows Update right?

    • If you have installed previous updates with same setting than BIOS password is not an issue. But you can try disabling it. Disable your anti-virus and try to install update again. You can try few more steps like removing previous update and thn install this new update. If that fails too, skip this update and wait for next update. Always create restore point before trying anything new, it will help if something goes wrong.
