Star Trek IV reference? :-) It only took 5 years for people to finally understand me correctly. I guess I made it too obvious this time, with finally adding the third alternative. :-)

@J-Mark-Barfield , that was not a “regedit”, that was a normal command-line command all those two commands did was run an instance of notepad++.exe without RunAsAdmin privileges, even before you made the change to the executable compatibility settings it was completely unnecessary all you had to do was exit Notepad++ application completely (so it wasn’t running), then do the steps I explained to get notepad++.exe to not run as admin, and then the next time you ran Notepad++ (either using your shortcut or double clicking on the exe or running the exe from the command line normally or double clicking on a text file or right clicking and choosing Edit with Notepad++) would have run Notepad++ not as admin if you didn’t exit Notepad++ first, then the still running Notepad++ instance would still be running as Admin. Changing the exe properties while the exe is running doesn’t magically drop the running Notepad++ out of Admin mode. And thus your right click would not have worked, because the running Notepad++ was still in Admin mode. all you did by doing those extra commands was close the Notepad++ that was running as admin open a new instance that wasn’t running as admin change the exe properties so that it wouldn’t run as admin next time (I understand that you got it working, so you don’t really care at this point. But I don’t want future people to read this discussion, and come to the wrong conclusion that they need to do your extra steps. Those steps were completely unnecessary.)
