Windows Update won't update anything

is it just me or does Vista want to give me an anneurism. MY problem is,
that windows update won't install the updates. It took me a while to finally
get Vista to use windows update. But everytime time i install the new
updates, it does it's thing. I shutdown, but before it shuts down it says
it's loading all the updates, I turn it back on, before it goes to the log in
screen, it's showing that it's configuring updates. But when i go to the
windows update panel, and look at installed updates, Nothing was installed,
and then it shows that windows update is ready to install the same updates
that i just tried to install. can Vista be any harder to use?

so does anyone have a solution, i've tried the ones that are on this thread,
but it's not working.
