Cumulative Update for Windows 10 Version 1511 KB3135173

I ran the troubleshooter for updates. It identified one issue ( this one) I then ran the fix and it claimed the issue had been fixed.
I then checked the event logs and discovered that the mail and calendar APP tried to update last night at midnight, which was BEFORE I started the download process for KB 3135173 !

So it seems there was a separate update for this App, that failed probably because just after midnight I lost connectivity. Now I wonder if the update this morning failed for this app because of the previous failure last night?

In any event, how the devil are we to manage our updates if these apps do their own thing?
Not at all happy! I want ALL updates to inform me first before they try and install by themselves! What is the use of being able to schedule updates if the store is second guessing you in the background?

Here is the answer care of a Tutorial!

Hi Geoff,
Did you try updating directly from the store? is what i did to update Mail and Calendar

Thanks for the tip! It started me on my quest to find out what went wrong. See the outcome of what I found in my previous post!

So is your mail and calendar app now working ok? If you go into store and manually check for updates does it pick any up? If nothing comes up then you can assume mail and calendar are now ok. I totally agree on the criticism of the app updates (especially the native apps), my advice would be to ensure the app update settings is set to manual. Check it periodically yourself. Then at least you have control and know what is updating and you shouldn't have any horrible shocks when an app stops working for no apparent reason.

The details relating to improvements made in this cumulative update do mention the app store "Fixed issue that didn't allow simultaneous install of apps from the Windows Store and updates from Windows Update." So perhaps app updates will be more reliable from now on. The phrase is a little ambiguous but I think it means that say Windows Defender was updating or simply that Windows Update was doing it's check for updates automatically (regardless of whether any are available) then it could bork the app update process if Windows Store was trying to do it's thing at the same time. But maybe I interpret that wrong. Either way, only time will tell whether app updates has improved.

Yes, did what you suggested and the App is up to date now. I agree with your analysis. Not sure if I am able to show that this is what is meant by the fix. So I have now used the process in the tutorial using the group policy editor to disable auto updates of installed Apps.

In our environment where we have very little control over connectivity, it is a very bad idea to have all these automatic processes which require reliable connectivity.
