how to add a shortcut in rainmeter?

First, find or create a .wav file saying what you want. If necessary, you can convert other files types to .wav using this: http://formatoz.com/

Then go to Control Panel > Sound > Sounds tab (this is for windows vista, but is similar in xp)

Scroll down to and click on Windows Logon. Browse to the clip you downloaded/created earlier.

Click ok and you're done. Answered Jul, 12 2011
