I just bought a new desktop with Windows 7 Home Premium x64. The first thing I did was to go to Windows Update and download and install any critical updates. I then went to Control Panel/System and noticed that SP1 was not listed under the basic information on my computer. Is this normal? If SP1 is not installed, why didn't windows update download it. If SP1 is installed, why doesn't it show in the System display? Should I manually download SP1?
