I have both a xps desktop and a inspiron laptop with an original Vista install. The laptop is 10 months old and the desktop is 3 months old. I cannot get windows update to show the service pack for either one. Both of them have the updates that get the machines ready for the downloads. I went through Microsofts 6 reasons why you might not see the update but I can't figure out what I need. I am just a normal computer user. I can't see why you have to be a "geek" to understand what is going on! Where can I find understandable explanations?
