W7 SP1 Failure

I have a problem with the installation of SP1, it won't install. I'm running W7 HP x64. It's on a new machine I got a couple of days ago, so I did a fresh install of windows, updated windows up to SP1. I realise that there probably isn't much to gain from installing the SP1, but I would like to get to the bottom of this issue, for myself, and for others also, if they are having the same issues.



When I try to install it through windows update it gives the error message 8000405. Looking up this code online doesn't really come up with much.



I've then downloaded SP1 standalone installer, and tried that, still won't work, giving the error message E_FAIL(0X8000405). It's then directed me to the Microsoft site to get help, so I've tried the Windows Update, troubleshooter, which seemed to correct some things on my system, but this didn't help. I've then downloaded the System Update Readiness tool, installed, and run SP1 again, still no help either through Windows update or the standalone.



I've the tried with my antivirus un-installed, guess what, no joy!!!!



I've read a couple of threads here regarding this, where people using things like ccleaner can affect the installation of SP1 but I have no programs like this running at the moment, so this won't be the issue.



So as it stands, I've run out of idea's, It's not an urgent need to get it installed, but would like to get to the bottom of it either way, so hopefully, for future reference for people with the same or similar issue, this could be a help.



Thanks in advance for any replies.
