Run Javascript in Windows?

Hey, I have a clock thing that follows the mouse cursor on a webpage. I want run the script when windows boots so it will follow the cursor all the time in windows (not just on a certain webpage. Can I save the code as a *.js file and write a vbprogram to shellexecute the file with "wscript.exe"? Any help appreciated.

wscript.exe is used only to run Windows Scripting files. Javascript can (technically) only run from within a webpage as that is how they are designed.

Do a search for some windows scripting agent scripts that do a similar thing to the javascript
