There seems to be lots of problems with this, I have now given up and I can only presume some restore partitions take win 7 back to far and they become un-updatable (sounds like a load of cobblers - yea me too) I have have had this now on 2 netbooks and have done everything, deleting selected items in Software Distribution (and deleting all of it and watch rebuild itself). sfc scan now and all the antivirus checks, even updated 'windows update', if I look in the windows update log you can see it finding what it needs but won't download it or install it. I have other machines that all work fine. I'm saying all this in case someone found a fix before I do a fresh install.
