I have looked all around the internet, and can't seem to figure out how to uninstall a WPI application. I accidentally installed something thinking it was something else, and now I can't uninstall it.
You could remove them via control panel. Depending on what you want to remove, you either need to: Go into windows programs and features and turn windows features on/off, locate the feature you wish to remove and untick it. Else Go to uninstall a program section and locate it that way and uninstall as you would any other program.
