Windows 10: Is KB2267602 installation required?

Today I looked at my Update History and noticed the following regarding KB2267602:

"Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.291.1488.0)(2)

Last failed install attempt on 4/9/2019 - 0x80070643"

I have seen some locked threads on this subject and am not sure whether to try and download it, if possible, or not. I can't find KB2267602 listed in my list of Installed Updates. I use Norton Security Premium and have the periodic scanning turned off in the Windows Security - Virus and threat protection section. (Maybe that is why it didn't update, or do I even need it?)

Windows Updated(16299.309).KB4088776 Restart is required to complete.


Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.

 

KB3097617 Update Bug + KB2267602 (1.207.2189.0)


I'm not able to complete the installation of the KB3097617 file (since 5 days). Try manual installation like suggested here:

How to Fix Windows 10 Cumulative Update KB3097617 Installation Issues - Softpedia

Did not work. The problem occurs on restart.

Got the same issue with KB2267602 but it was solved by Windows after several attempts. Will try like suggested in the link above to disable Defender...

Edit: KB2267602 (1.207.2189.0) Was never able to installed that file. Ubuntu or Grub is not the source of the bug.
