Windows 10 Updates - KB2267602 Security Intelligence update Fails to Install

Question

Today I took a generic Windows 10 20H2 machine and decided to update it with the 'keep nothing' option. After the initial install I set the proper time and did a WIndows Update. The update installs but hangs up on KB2267602 and gives me the error 0x80070643.

I am doing a fresh install and 20H2 bombs. Very sad.

Answer 1

Wow. I tried the troubleshooter. Did not fix the issue. I tried to rebuild the update catalog. Ran into permissions issues even when admin and didnt want to play around with that. Besides all those steps would make one certifiable.

Keep in mind this is a reinstall from the latest Windows 10 20H2 ISO where I tried 'keep nothing' and I also booted and deleted the existing disk partitions.

One possible fix is that now the WIndows updates are 'asynchronous' but you need to wait. You get the silly 'restart' button but Windows Updates are still downloading and installing. So I waited for everything to finish before a restart. I did this before. But for some reason when I did it now it worked. There seems to be some dependencies with KB2267602 and others in the install order. Maybe MS addressed this today?

It is rather disheartening that on a fresh reinstall this type of issue would come up. Right now I am leaning towards the problem being an install timing / dependency issue. As such all of the above suggestions are of less help as this is appears to be a Microsoft issue.

Here is what the list of updates for Win10 20H2 look like on a clean reinstall:

Answer 2

Since this is a recent fresh install computer, you could install the latest SSU and the latest CU, after this, your computer has been up to date.
About Microsoft Defender update, we usually don’t need to care, Windows Defender will update itself with Windows Update. Or you could manually install update for it from here:

It appears there are some strange dependencies that need to occur and then it works. Speculation is some magic incantation will make this work (just kidding). Hopefully this is a blue moon type of event in regards to updates. Although the last 4 months have been rather rough. My fix is patience and luck (wow).

Answer 4

Hey guys i have found that running this command helps:

cd %ProgramFiles%\Windows Defender
MpCmdRun.exe -removedefinitions -dynamicsignatures
MpCmdRun.exe -SignatureUpdate

After the commands has been executed in cmd, check for updates again and it should be gone.
