Changing Icons

[thesurge]

So, I have a folder full of .ico files downloaded from interfacelift, and I want to mass change my icons without having to do them one by one. What should I do/use to achieve this? Is there a way of easily switching between the default windows icons and this theme of icons?

thanks.

I believe Stardock has an app called IconPackager not freeware though
