I didn't see anything like this, so i figured i created it.
The objective is to uninstall an application by right mouse clicking it's shortcut, and then selecting the uninstall in context menu.
To make this work you simply run the exe to set the registry/context menu. To remove the context menu entry, run it again.
That's it, it will only be called when there's a right mouse click in a shortcut file and the entry is pressed.
Then it will search the registry for the path of the application and start the uninstall exe from respective application.
From then on, the user has to go through the uninstaller process for that application.
Any problem let me know.
