Windows Update Fails

[detroitphan]

I keep getting failure messages such as the ones below (unfortunately there's plenty more) due to Windows Update failures. I would love any help as to figuring out some of them! As a side note, I noticed an issue with MSN, but can't pinpoint what exactly the issue was. I apologize in advance for any and all vagueness. Thanks

Yeah, none of those helped. Thanks though! I've attached a screenshot of the failing updates:
