Save It as a Reg File
Saving files in Notepad will almost always result in the file being named with a TXT extension. If you want to save the file with a different extension, say a REG extension (for a registry hack), check this out.

Enclose the new name in quotes. For example, to name your file Regfile.reg, choose File, Save As and then type in

"Regfile.reg"

and click Save. This should save the file with the .REG extension, and not a TXT extension.
