How do you fix an error 57E

This is a repeated error code which despite Vista SP1 being installed has not
cured my problem. However I can offer this slight bit of salvation which has
done me well over the past 12 months. Should any updates fail to down load
and all your favourite error codes suddenly manifest themselves - do the
following. Go into microsoft support and type in the download, ie KB12345, it
may take a while to find the right branch of Microsoft, but in every occasion
I have found what I have been looking for. I hope this helps.
