Unable to install 2018-04 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4093112) Error Code 0x80070020

Hi Wesley,

Let's try to Manually Purge the Update Cache

First, you need to temporarily turn off the Windows Update service (to stop background downloads). Open the Command Prompt (click start and type “cmd”) the type

“net stop wuauserv” command, and press Enter.

Open File Explorer, and go to View > Folder Options. Select the Show hidden files, folder, and drives radio button, and click Apply to enable the display of hidden files on your computer.

Once done, navigate to C:\Windows\SoftwareDistribution\Download and delete the content of the Download folder.

Open a new Command prompt window, and run the “net start wuauser” command to restart the Windows Update service.

After this, reboot and then try to run Windows updates again. Let me know!

Hello,

I am Sumit, an Independent advisor and a Microsoft MVP here to help.

Regarding your issue, I would first suggest is to

Try resetting Windows updates using an automatic script. See:

Make sure you run the script as an administrator.

Please let us know if you need any assistance.

i followed your steps but after entering "net stop wuauserv" on "cmd" screen showed access denied. could not follow your instructions, i think it is incomplete. please elaborate complete steps so that i could fix this. thanks in advance.

Hi "Messenger" Sumit,

I have followed all the advice after having followed Charlie K's advice and still no solution.

Just keep unloading update and re-booting twice to unwind the update loaded. I installed the updates manually after deleting the cache folder and that didn't work with the batch file.

Regards

Charles

Hello Charlie,

I am having the same issue. I followed you steps but it didn't work.

After my computer got reset from the beginning of April, I got this update problem.
