Go into settings, there should be a Windows Update. Install it and you'll be fine.
Oh yea, be sure to check out the search button. It's on the top right if you're in the webpage. It's very useful to look for things you don't know and useful to spare forummers the annoyance of having the need to pinpoint directions.
Thanks for your quick response. As you can se on the pix, it says, that there is no update available, not even the regular windows update. thats why i wondered ?
