I have a Dell laptop with Windows 8 (Ugh!) on it and I want to uninstall Adobe Photoshop Express. The program is not listed under "Apps" and does not show up on the Control Panel under Uninstall or change a program.
Search for the app in the main page of "Start" on the little window key! Then you click in the arrow that appears below when you pass the mouse over there, and you'll see all the apps from "Store" here you can click right button and uninstall the app that you don't like!
