I just installed a clean drive-wiped version of Windows 10 this morning. Hours later, multiple problems getting the updates to install, I come to this one. My build is 21H1 (OS Build 19043.928). Like several others, I resorted to the Microsoft Update Catalog for this one. The others actually worked. After waiting for it to download, Windows decided to block it because it could be harmful to my device. What??? Thinking it might have been corrupted or something the first time, I downloaded it again. Then, when I reassured Windows it was ok, and I tried to get it to install, I was told the data is invalid.
So, I looked at what was cumulative. Thirty eight files are in this cumulative update. Go again to the Catalog, download one, and Windows Update Standalone Installer tells me error 0x8007000d, The data is invalid. That particular one was KB4557957.
Next tried KB4567523. Same.
Then KB4560366. Yes! Success!!
KB4565503. Data is invalid.
Just great.
You get the picture.
