I have a Windows 7 Home Edition 64Bit laptop.
No CDs provided these days with a new laptop.
System came pre-installed.
I did restore the system from the recovery DVD I created just after completing setup. In order to be sure all was working correctly, and DVD was fine. I figure from what I have read above this could be the issue?!
I have ZERO pirate software installed, with all other windows updates installed sucessfully, and maybe one week with a fresh windows installed.
I can not install SP1 via Windows Updates.
I'm now downloading the stand alone version to give it a try.
I will post the results soon.
