Windows10 Update: kb3093266 - What Does It Do?

JAllenChicago, I can't answer that for anyone else but me. However, for Win10, since the data store was cleared the next update, actually the KB3093266 update in this case, downloaded and updated immediately after a restart from performing the above mentioned fix with no failure to install issues. It is now in my clean history log.

Follow these instructions to effect a cure for this problem:
Method 2: Steps to erase Windows Update historyNote:Erasing the windows update history will just remove the entries of the updates and not really the updates itself.
a. Go to menu Start> All Programs> Accessories. Right click on the "command prompt" and select "Run as Administrator".
b. Copy/paste the below command:
c. net stop wuauserv
d. And select OK.
e. Wait until confirmation that the service is stopped.
f. To delete the file, copy the following command in the command prompt:
g. del %systemroot%\SoftwareDistribution\DataStore\Logs\edb.log
h. You can also delete it manually by going to the location in windows explorer.
i. you can restart the service with this command:
j. net start wuauserv

This update was failing for me with error code 0x80004005. This fix worked for me EXCEPT I did not need to delete the entire contents of SoftwareDistribution\Downloads. I just stopped the Windows Update service, renamed edb.log, restarted Windows Update service, and then the update downloaded without incident. Thanks a lot!

Excellent, LopeDoggie. It looks like the solution you found and shared is catching on. It's too bad that the majority of users don't visit forums like this. They call Uncle Louie, or just put up with annoyances.

This update KB3093266 may cause a recurring update failure (12 in my case) addition to your update history logs or in other words, your pc will enter into a continuous update failure loop while using the win10 auto update feature. There exist a myriad of fixes for this issue on the web and I tried several with no positive results. I was however, able to fix this problem, based on earlier experience with other MS OSs on my PC.
A corrupt update to the win software distribution downloads and the software data store is causing this problem (In my case)

Windows updates failed, Want to delete all failed update files in - Microsoft Community

As I said it worked for me and I was chasing this problem down for about 5 hours. FYI it should clear your update history file of all entries up until your latest and newest update. Don't worry it does not erase the actual update and when everything is working in the win update world as it should you will have a new history file showing hopefully, only a good KB3093266 install. After everything has settled down and your version of Win10 is fully functioning again you may view all your win updates by clicking on the "uninstall update" tab in the View Your Update History page.

This a larger update more than 1 gig after the install is complete. The Excel file accompanying the update in itself is about 1.8mb in size and it appears like a rewrite of the win10 maybe even the core program. Please correct me if I am wrong.

KB3093266 manually download:

Mine wouldn't install at all. 2 x Windows 10 machines, one home. one Pro. I got an error code. Sorry forgot the code, but it means a problem with internet connection. I have no such problems.

I used the MS Hide executable utility (wushowhide.diagcab) to hide it and stop it from pestering me!

As far as I can tell there are no issues and whatever it adds can't be much otherwise the internet would have that info everywhere! I haven't bothered trying anything else to install it.

I think someone on this forum mentioned that it will all be installed with the next build to be released in November. So, I'm not bothered and won't trouble shoot it until I hear that it is important. (which I doubt) I have all other Cumulative updates, and this is the first time an update wouldn't install. Ah well....
