I tell ya, I'm tired of Windows constantly complaining that it's not up-to-date, but every time I say, "Okay, go ahead and update," it comes back and says, "Derp! I goofed up."
The failure code I usually get is 0x80070002.
The latest offenders have been KB5001649, KB5000802, and KB4601319.
I've tried all the suggestions on the usual Google search results... run the update troubleshooter, deleting update files, downloading the standalone installer from the Microsoft update catalog site, etc. etc. etc.
Now I just want Windows to shut up about it already.
