An old trick of mine was to replace notepad.exe with something else. It's an old trick and one I've used since filenames can into use. (Umm, I programmed on the GE-210 which had no files or names.)
I'M CONSIDERING A <span id="INSERTION_MARKER">TEMPORARY NAME CHANGE OF MS PAINT IN ORDER TO INSTALL ANOTHER COPY TO POSSIBLY CORRECT AN ERROR. IF I DELETE IT AFTER CORRECT INSTALLATION OF THE NEW COPY DOES THIS PRESENT A PROBLEM?
