Hi.  I cannot complete windows updates, and SFC and DISM is not correcting the issues for me.  My pre-scan with Windows Repair identifies 46 missing .cat and .mum files from the service stack KB4586864.  I am unable to uninstall or reinstall KB4586864.  I have downloaded KB4586864 and would like to unpack it and copy the files into the appropriate directory (C:\windows\servicing\Packages\Package_10_for_KB4586864~31bf3856ad364e35~amd64~~19041.621.1.0.cat  etc.).  Could anyone point me to instructions on how to proceed with this.

Your assistance is greatly appreciated.

Regards,

Open either a Command Prompt (Admin) or Powershell (Admin) and enter this cmd to remove that update.

wusa /uninstall /kb4586864 /quiet /forcerestart

You can copy & paste that cmd to the prompt to avoid typos.

The machine will auto reboot then go to Settings/Update & Security and run a manual check for updates to see if it picks it back up.

Thank you Boggin.  When I run the cmd you suggested (I've tried both Cmd Prompt admin and Powershell admin), I don't get any errors, but a pop up "i" window opens with a glossary of switches for the wusa command.  The PC doesn't auto reboot, so I wonder if the cmd ran.  I'm going to manually restart now and see if anything has changed.  Thanks.  I will report if this removed kb4586864.

You could try the cmd again but without the /quiet and /forcerestart on the end.

wusa /uninstall /kb4586864

Then reboot.

I've found that quiet doesn't work on Win 10 and there was no forcerestart in the wusa help menu.

It looks like the Google article I came across was incorrect - sorry about that.
Tom.
