I recently was told to update my Vista enabled laptop which is fine. When I tried to do it it said that I had to install an update for Windows update (How ironic I thought) so I clicked "OK" and allowed the operation through UAC and waited for a while but it keeps saying that the install failed with the code 800B0100 and the Microsoft help system is still as useless as ever.

Any help would be good, I like keeping my laptop up to date!
