Playing hidden object games on touch screen pc

I want to buy an Inspriron 3000 2 in 1 laptop but I can't play my hidden object games on the touch screen. I can't get the cursor to show. I have to touch the screen to choose the object and my fingers are to big to get some of the things. Is there some way to get the mouse or trackpad to work with these games?

Thanks for your help
