Yesterday I installed a program on my Windows 10 computer. When I open the "Programs & Features" link on Control Panel that programs does NOT appear in the list. Likewise when I go to Settings>Apps there is nothing in the list that corresponds to that program. Since I know where it got installed I proceeded to remove it from that location. My preferred method of choice was to first move the main directory for the program's executable files from "c:\Programs Files" to a directory that I created for that purpose. I also knew that there we data files for this program located in c:\ProgramData, so I also moved that main directory to my newly created directory.
Then as expected this did NOT do anything to remove the Icon's (?shortcuts) from the Start Menu so I went ahead and selected one of them. To my surprise the program was launched and seems to function correctly. If I right-click on said Icon and then select uninstall I'm taken to the "Programs & Features" page of the Control Panel which provides NO entry for uninstalling. However, if I right-click and select "Open file location" it opens File Explorer in the sub-directory of my newly created directory where the program is now located.
This is all very strange to me but I do think there should be a way to properly remove such a program and apparently that is unknown to me. Please explain how it should be done?
