If you are tired of scrolling that Open With list because your most often used programs are not at the top of the list:

1. Type: Copy "<Drive:>\Directory\ProgramName.exe" "<Drive:>\Directory\_ProgramName.exe"

2. Type: ftype JSIfilen="<Drive:>\Directory\_ProgramName.exe" "%1"

Example: If you want to have Notepad and Wordpad at the top of the list:

Copy %SystemRoot%\Notepad.exe %SystemRoot%\_Notepad.exe.
Copy %SystemRoot%\System32\Write.exe %SystemRoot%\System32\_Write.exe.
ftype JSIfile1="%SystemRoot%\_notepad.exe" "%1"
ftype JSIfile2="%SystemRoot%\System32\_Write.exe" "%1"
