Uninstalling FSX and Addons

Hi,

I am trying to get ready to install FSX Steam by uninstalling my current FSX and Addons. I went down the windows 10 uninstall / install list and uninstalled any Addons in the list. Each one said the program was removed successfully. Upon going to the Windows desktop and the app and program list, I see several icons and programs are still listed. When I right click on them, I select uninstall which takes me to the Windows uninstall page I already used and shows no entry to delete the program.

For example, Flight 1 is still there on the desktop with its icon for ultimate traffic 2 along with the path to FSX and the ultimate traffic 2 directory. None of the orbx scenery is listed in the Windows uninstall page and I could not find an uninstall option within the orbx central panel.

How can I remove these programs and make sure I got it all? I do realize some programs such as active sky have their own uninstall options. My problem is those that don't seem to have their own uninstall option.

Thanks. Tom
