I am using windows 8.1 and i have a lot of games,apps downloaded and installed on my machine that i cannot easy manage them so my suggestion is to add an part on Unistall manager of CCleaner to manage and the Windows Applications so i can unistall them and manage them easy as the programs.
When using a mouse just mouse over its tile, right-click, and then choose Uninstall from the options toolbar that appears at the bottom of the screen.
Using touchscreen just tap and hold a tile, drag it down just a tiny bit, then release it. A checkmark will appear in the corner of the tile and the toolbar down below. Now you can tap Uninstall to remove the app.
