Out of curiosity we install many programs. But we never use them. We don't even worry about removing or uninstalling them. Those who want to uninstall sometimes are unaware of the right methods of uninstalling. If you are one of those then you can follow these steps to remove the programs in windows.

Open the Start menu and select Settings, then Control Panel.
Double-click on Add/Remove Programs.

Find the program you want, then click Add/Remove.

In the box that appears, confirm to remove the program and click through the Wizard that follows.

Note: While uninstalling applications, there maybe a pop up window saying that some of the files are shared by other application and asking you to confirm whether you want to delete them. Such files are usually (.DLL) files and if you are not sure then it is safe to leave these dll files.
