Came across an interresting issue today. You know how normally when you type a file name such as "regedit" it will open "regedit.exe". Or "cmd" opens "cmd.exe" or "notepad" opens "notepad.exe". Well what do you suppose it means when you type a name but it adds ".com" instead? So if you click start-run and type "regedit", it tries to open "regedit.com" instead of EXE. Note that you can type the full filename regedit.exe or whatever, and it opens fine, but the default extension turns to .COM somehow. Not sure what that means. So how do you tell Windows to look for EXE instead of COM when typing a filename?
