Update for Windows Security platform - KB5007651 (Version 1.0.2109.27002)

Did you find that option Manage Settings ??

Thank you again, Yung Shaywop, I actually use Bitdefender, so I did the equivalent and switched off Bitdefender Shield. But that does not solve my problem - Windows Security is trying to open something that does not exist. Unless you have some solution to that, I think I will leave the problem for now - it does not stop me using my computer.

It seems that this error in the KB5007651 is reported differently in my Event Viewer.

Whilst the error listed in the Windows Update failure is 0x80070643, when I look at the Event Viewer errors, the source is shown as

Event 20, WindowsUpdateClient, and the error in the General description is given as:-

"Installation Failure Windows failed to install the following update with error 0x8024200B: Update to Windows Security Platform - KB5007651 (Version 1.0.2109.27002)".

Which is it? More to the point, what's the cause, and what's the fix?

I have exit kaspersky from the process also checked in task manager it's not there still no option

can you guide me where it is ?

Since you have Kaspersky active, The options for windows security are not shown. Turn off Kaspersky (Entirely). Then Follow these steps:

1. Search "Windows Security" in Start. Open it.
2. Click on "Virus & Threat Protection".
3. Under Virus & threat protection settings, click "Manage Settings".
4. Turn off Real Time Protection.
5. Go to Windows Update & retry the buggy update.
