Windows 10 Updates - KB2267602 Security Intelligence update Fails to Install - Again on April Patch Tues

Using the latest Windows 10 20h2 download ISO. Install over an existing version to keep license key but wipe out the disk partitions. Run the security update. Update for KB2267602 fails. This is on a fresh install with no modifications. Ongoing issue for months. Was hoping April patch Tues was reliable - not. See images for detail. Month after month of instability. When will there be reliable updates?

Run Windows update troubleshooter firstly, this tool can diagnose and repair update issue automatically.
Then, restart computer and check for updates again.
If still no help, reset Windows update component manually:
Open an elevated command prompt windows, type the following commands one after the other, and hit Enter:

net stop wuauserv
net stop bits
rename c:\windows\SoftwareDistribution SoftwareDistribution.bak
net start wuauserv
net start bits

Open an elevated Command Prompt, type the following command one after the other and hit Enter:

net stop cryptsvc
md %systemroot%\system32\catroot2.bak
xcopy %systemroot%\system32\catroot2 %systemroot%\system32\catroot2.bak /s

Move to C:\Windows\System32\catroot2.
Then, Delete everything from this folder.

Now, Run the following command.
net start cryptsvc

Once you have done, restart computer and check for updates.
On the other hand, you could manually install Microsoft Defender update from here:

When doing a fresh install of Win 10H2 the monthly update KB2267602 does not install. It appears this occurs due to an asynchronous timing issue within Windows. Before KB2267602 can install some background tasks (which appear to be system security 'checks') need to take place. This can take some time. I have found I have to leave the system running for a while (more than 5 minutes) before the Windows install and other updates 'quiescence'. Once that happens KB2267602 installs correctly. Patience is a virtue ...

Glad to hear that you have resolved KB2267602 installation issue.
You are right, a clean install new system needs to some preparation work before working smoothly, Windows Defender update can be downloaded and installed with normal Windows update, so it should have an order.
You know, Windows update process has a Rigorous process and 4 phases:
Scan, Download, Install and Commit. Before KB2267602 install, system will scan current KB install state and download precondition file, this process will cost some times(in your words more than 5 mins), that is why you facing current condition.
Thanks you for sharing, I believe this case can help other Q&A forum users.
