How to Uninstall "Minecraft"by Charlotte Mission ; Updated September 22, 2017
Unlike many games, Minecraft doesn't require you to install or integrate any components into your system. While this is good for disk space, the game doesn't appear on any lists of installed programs on your computer. This can lead to frustration if you don't know how to remove the game from your computer or do an uninstall/reinstall to solve issues such as freezing and crashing. Instead of using Windows' Add or Remove Programs function, you must delete the Minecraft folder to uninstall the game.
Press "Win-R" to open the “Run” application. Type “%appdata%” into the text box, and then click “OK.”
Right-click the “.minecraft” folder, and select “Delete” from the list of options.
Press “OK” in the dialog box to confirm your decision to delete the folder.
You can keep your saved games by moving the “Saves” folder from the main “.minecraft” folder to another location on the computer before deletion. This allows you to restore your previous games if you decide to reinstall Minecraft.
