In the right frame scroll all the way down until you locate
Windows Modules Installer

Is Windows Modules Installer listed ?
Under 'Startup type', what does it say ?
To the left, click the Start service link if the service is listed.
Did it Start ?

Now do the same for Background Intelligent Transfer Service (BITS)
and the Windows Update service.

Are all of the above services listed ?
Can they all be Started if they are not running ?

Sorry for the long message but i finally found a solution. I contacted microsoft and one of there techs answered back. ( 4 days later i may add)
I have Vista Home Premium X64 with sp 1

Step 2: Manually restore missing file
