Windows Update fails

I'm currently experiencing a slight windows update malfunction.
Actually, it's totally broken. Tells me there are new updates,
then i click instal, it starts and then,

Error
Code 80246008
An unknown error has ocurred bla bla bla

Windows help gives me some info about changing settings for
Background Intelligent Transfer Service in services.msc,
however, no such service exists on my pc.
Also Windows Event Log is mentioned but those settings are as recommended by microsoft.
Microsoft support offers no solution. I have not been able to find a manual install for these updates KB2418240 and KB951847
But anyways i think the underlying issue here is the BITS problem.

I'm running windows vista 32bit home basic and have recently had a zeroacces rootkit infection wich i succesfully removed, with help from this forum, though i'm not sure this has anything to do with it.

Any suggestions appreciated!

scroll down to Method 2 and then look under
The Background Intelligent Transfer Service is missing to see what you need to do.

 

You can also try to automatically fixit using http://fixitcenter.support.microsoft.com/

 

Thanks very much but these options do not work, on both of them i just get an "installation failed due to unkown error" notice with no further details.

 

Run sfc /scannow

to get the missing files back in the proper place.

 

If the System File Checker also fails to cure your problem, then maybe your next step will be to try a Windows Repair installation.

 

Good lord.
Guess i'll start digging through years of shit to find my windows cd then... :confused
