On Windows XP, Windows 7 and Vista, remove or change software from the Programs and Features window in Control Panel. The steps to install a program differ for each program and usually consist of running its installer. Some programs also have options to be modified or repaired in Programs and Features.
To open Programs and Features in Windows 7, open the Control Panel from the Start Menu and make sure the view is set to Default. Under Programs, choose Programs and Features. From that window, select any program and click either Uninstall or Change and Repair. Some programs may include their own uninstallers in Start Menu program folders.
In Windows 8 and Windows 10, apps can be removed by holding down or right clicking on the app and pressing Uninstall. The procedure for uninstalling programs is similar to that of Windows 7. Open the Control Panel from the Start screen, and click Programs and Features. Choose the program, and press Uninstall.
Since Windows 7, there has been the option to modify or repair a program. This is useful if a program didn't install correctly or needs to be reinstalled to reset or change settings. When in Programs and Features, choose Change or Repair instead of Uninstall.
