Back in the day, a not-insignificant number of Windows users ended up with Apple's Quicktime software installed on their computers, thanks in large part to iTunes. It's been a long time since it's been necessary for either the web or iTunes, though, and as such the software is pretty out of date -- not to mention a security threat. Last week, the Department of Homeland Security recommended Windows users uninstall Quicktime because of potential security holes, and now Apple is echoing that advice. The Wall Street Journal reports that Apple has confirmed it'll no longer update or support Quicktime 7 for Windows. Details to remove the offending software from your computer can be found here.
