According to Microsoft Win7 starter is unable to create an ad hoc network. Am trying to screen share an iPad with a laptop without 3G needed.
A quick search on Dr. Google reveals that the ad hoc network option is actually there in starter, but the link is missing. To set up an ad hoc network just click on start and in the box "Search programs and files" type "ad hoc".. this will bring up the wizard and away you go.
Will add to the post how well this goes with screen share with iPad
