Fix Windows10 Cumulative Update KB3093266 Fails


Windows-Update-failMicrosoft recently issued a cumulative update for Windows 10 (KB3093266) which has been problematic for quite a few users, myself included. In my case, installation failed with the error code 0x80004005. Running the Windows Update troubleshooter informed me that there was a problem with a registry corruption, which I seriously doubted, and Running the System File Scanner tool via the “sfc /scannow” command confirmed zero integrity violations. So, it was off to the internet to see if others were experiencing similar issues with this update.

I quickly learned that I was not alone, there are indeed many reports of failures when trying to install this update, not all identical but very similar. I finally stumbled upon a solution which worked for me:

  1. Open an elevated command prompt and copy and paste the following command: net stop wuauserv, then press Enter
  2. Wait for confirmation that the service is stopped
  3. Delete the edb.log file by copying and pasting the following command into the command prompt: del %systemroot%\SoftwareDistribution\DataStore\Logs\edb.log
  4. You can also delete the file manually by navigating to the location in Windows Explorer
  5. Now restart the service with this command: net start wuauserv
  6. Restart the computer

As I said, this worked for me and the recalcitrant update installed without further ado. However, it hasn’t worked for everybody so your mileage may vary.
