With Internet Explorer 7 out, a lot of Windows users are starting to update their browsers. But what if you want to keep Internet Explorer 6 around for occasional use? Windows doesn't make it easy to run multiple versions of Explorer on the same computer, but that doesn't mean there isn't a way.
Go to a site that has downloads of older browser versions, such as Evolt.com. You can find multiple versions of Explorer 6 and 5.5, along with other browsers, and it's all free to download.
