Error uopdate Windows 10 Microsoft Defender Antivirus - KB2267602 (version 1.343.816.0)

Question

I'm having troubles updating KB2267602 (version 1.343.816.0)

"There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070643)"

I have run possible solutions listed under 0x80070643 but It did not solve the problem, I have reinstalled my Windows 10 but still I got the same error.

Answer 1

Firstly, Simply clicked "Pause updates for 7 days" and then "Resume updates", it reinstalled the same update, check the result.

Besides, You could update Windows Defender directly, from Windows Security -> Virus & threat protection -> Virus & threat protection updates -> Check for updates. Next, Windows Defender will update itself.

Also, you could go to the following website, Manually download the latest update on Microsoft Defender Antivirus for Windows 10 and Windows 8.1 and install.

Answer 3

Have you tried my first suggestion: Simply clicked "Pause updates for 7 days" and then "Resume updates", it reinstalled the same update, check the result ?

According to your screenshot, you need to go to registry:

Run System File Checker tool to repair missing or corrupted system files
