Cassandra,
I have not successfully installed any Cumulative update since mid to late March.
I get the same error every time - 0x800f081f.
I have tried all the suggestions I could find to get updates working again with no resolve.
I have turned updates off.
Actually, I am one of the lucky ones, some of those that were able to get some of these recent updates to install, have suffered from myriad of issues....sound, keyboard, drives and in some cases the inability to boot.
Someone recently had posted that this is public forum and NOT a Microsoft help line, my question for that person is why is the URL "answers.microsoft.com"?
Bob.
