Hello :)
No, you should not be seeing any errors. They mean that something has gone so drastically wrong that Windows Update can't handle the unexpected problem by itself. Of course, in the ideal scenario, nothing of that nature would happen, hence no errors. So, if you have no errors, that is perfectly normal, and indeed is "good". Think of all the millions of Windows users, and now how few Windows Update errors there are per million users. OK, so we collect them here, and at other forums, but still, the vast majority of the time it works perfectly.
There is no need to change any settings - errors will show by default if any occur, but ideally, you should never get any in the life of a computer. Ideally :)
Some are caused by e.g. hardware failure which leads to corrupt files. Otherwise files become corrupt in other ways. But files aren't supposed to become corrupt, so the fact that yours are not is a good sign.
