Windows 7 Pro hides the games by default because it's not strictly a "home user" version. Got to Control Panel->Programs and Features->Turn Windows features on or off. Look for Games and tick the ones you want.
I can't find Freecell or Spider on Windows 7 Professional. I used a cable transfer to move all the XP files to my Windows 7 Professional machine
Thanks for the response. I had already found my way to the games while looking for another problem. I was using Power Point Viewer Vers 3 but it kept asking me to register. I kept trying to register even though I did when I first downloaded it a year or two ago. So I went to Microsoft and downloaded ver 7, works great, but whenever I click on a PPS files in a download, Vers 3 opens up and we go through the register prodecure again. I keep trying but Microsoft no helping. And, it doesn't show up in Programs and Features so I can't uninstall it.
