Not sure. I would need to know which updates to download and it can't even get that far. Even trying to open it from the Control panel causes the window to freeze at the moment.
I do recall it seemed to have a problem with either the last or last but one set of updates it downloaded - said some failed but then worked and I'm pretty sure that's when it started having the issue.
I'll try rolling back to see if that sorts it. Just need to work out how to do that - windows help here I come!
