I wanted to state that this method works!
I too had the issue with the two updates but decided to wait until after "patch Tuesday" before jumping on the reinstall windows option.... Maybe Microsoft will actually fix a problem.
Imagine my angst when, on Tuesday, I now had THREE UPDATES that wouldn't install. Thanks Microsoft!
After I came across the article bondisdead posted....
Thank you for this thread! For me I had to 1) disable all Real-Time Protection features of Malware Bytes: Web Protection, Malware Protection, Ransomware Protection and Expliot Protection and 2) open Windows Features control panel, then uncheck .NET Framework 3.5. After a restart and a few pop-up messages from programs which probably required .Net 3.5, I was able to install updates KB5015814, followed by KB5015882. I then re-enabled .NET 3.5 framework and Malwarebytes Real-Time Protection features. Windows update is finally clean after the last 1+ month, and a bunch of useless generic YouTube vides.
...., I decided to give it a try and I can say that (with a few more reboots than suggested in the article) this method absolutely works. My PC is now all caught up again.
I do hope that this will not be something that I (and all of you) will have to do every time from now on... we'll see.
Thanks to one and all who have gotten us all here.
