Remap original hotkeys from Winamp to media keys, disable the annoying CaPS LoCK button, allow the volume to be adjusted with the mouse wheel, and quick launch a calculator using Num Lock.

Install AutoHotkey and run the script directly.

I like to right-click the script, compile to an EXE, and then drop the file in my start up folder.
(run shell:Startup to find it)
