How do I do that?

Have you tried saving a blank file in UNICODE format and double clicking 
a shortcut leading to that file instead of starting Notepad with the 
normal Notepad application shortcut?
There is a "IfCharset" key with the value of 0 in the 
\HKEY_CURRENT_USER\Software\Microsoft\Notepad section of the registry. I 
don't know what effect changing that key would have. That  key is 
duplicated in another part of the registry too (do a search). CAUTION: 
experimenting with registry entries could have serious and unwanted 
effects on your applications and operating system.
