You may notice that Google Chrome does not update your website’s favicon when you do because it stores a copy locally on your computer. So deleting your browser cache doesn’t do anything. Instead, you have to go to: C:\Documents and Settings\%USERNAME%\Local Settings\Application Data\Google\Chrome\User Data\Default on your Windows machine, in this case Windows Vista, and delete the Favicons file. Of course, make sure Google Chrome isn’t currently running when you do. If you’re not confident about the change, then you can move the file or rename it. But Google Chrome will automatically generate a new file anyway.

So when you revisit your site, Google Chrome will re-cache your updated favicon. Noice.
