That's how I see it too.

Nope also.
Try this at a cmd.exe:

D:\ETC\Tools>assoc .=3DMyDefaultLauncher
.=3DMyDefaultLauncher

D:\ETC\Tools>ftype MyDefaultLauncher=3D%COMSPEC% /C "%1"
MyDefaultLauncher=3DC:\WINDOWS\system32\cmd.exe /C "%1"

D:\ETC\Tools>regtool set "/user/Software/Microsoft/Command
Processor/AutoRun" 'set PATHEXT=3D%PATHEXT%;.'

Now, try this in a Windows explorer: rename joe.exe (or vi.exe, or
whatever...) to remove the extension.
Now double-click it, and "voil=C3=A1".

DISCLAIMER: This is only a proof-of-concept. There are clearly some
rough edges to remove, but this should give you the general idea...

Hm. Maybe they shouldn't.
After all, the .exe magic has been around also so that kind of scripts
DIDN'T needed that kind of expectations :)

+1 from me.
