Hello QTQL3,
Excellent! Glad to hear you're up and running again :)
Yes, I'm afraid it's an unfortunate side effect of deleting the SoftwareDistribution folder, but there is no way to preserve it so it's just something we have to deal with.
There's only one way to find out what solved it: try it on another thread! Let's see how this goes:

The FixIt will have fixed the 0x800B0100 that Windows Update was complaining about, but who knows whether than has any connection to your other error.
