Windows 10: Windows Security - IT error message when I run Scan

Ever since 1903 in June when I do run a scan using Windows Security I get this error message>>




The scan runs in full ( I guess) but I never see results and I get this message.


How do I get rid of this?


I am the administrator!!!

Windows Update Error Message 0x80070543


Ya Ya Ya, there's over a hundred threads like this, ...

Anyway, started getting this error message a few days ago, and done a lot of searching on this error message, apparently it's not, uncommon.

In particular, the (currently) 4 updates that are being affected are:

• Update for Windows 10 Version 1511 (KB3173428) - Error 0x80070543
• Security Update for Windows 10 Version 1511 (KB3172729) - Error 0x80070543
• Security Update for Adobe Flash Player for Windows 10 Version 1511 (KB3174060) - Error 0x80070543
• Cumulative Update for Windows 10 Version 1511 (KB3176493) - Error 0x80070543

The actions I've taken to date are:

1. Uninstalled firewall program (comodo)
2. Uninstalled anti-virus (Avast)
3. Reset the windows update catalog on local machine.

So the above errors are with the above done.

What other steps should I be taking to resolve the issue?

Below is notations for when I actually add to this thread.

1. Attempted to use the troubleshooter, no dice.

 

ERROR 53 message

Hello,

Run-time Error 53 indicates that there is a missing Windows component. A program you're trying to use will display that error message if the program is attempting to use a dynamic link library, or DLL, file that has been deleted or was never installed properly.

We would like to know some information:

• Have you done any changes on your computer prior to the issue?
• What troubleshooting steps have you done so far?

For initial troubleshooting steps, we suggest that you try to run
System File Checker. It will scan for corrupted files and restore it.

If that didn't work, we suggest that you try to uninstall and reinstall the app.

Hope it helps. Let us know how it goes.

 

How to run a full security scan

How do I get Windows 10 / Windows Defender to do a security scan of my computer? I can't find Windows Defender in the list of apps. I can't find an icon to click on to run a full scan.

Thank you for information.
