When I tried to change my IE 7 to IE 10, a message came up that IE 10 can only be downloaded for windows service pack 1 or higher. So from this trial effort, I now have IE 8 instead of the previous IE 7. I looked at one microsoft web page ( below ) for downloading windows service pack 1, and it looks complicated with all those many buttons. http://www.microsoft.com/en-us/download/details.aspx?id=5842 Is there an easier and better way ? How do I determine what windows service pack is in my computer now ?

If Service Pack 1 is listed under Windows edition, SP1 is already installed on your computer. ________________________________________ And the result says nothing about the service pack at all.
