Internet Explorer's biggest security flaw has always been its support for outdated plugins. Microsoft's latest update looks like a move to stop dangerously outdated plugins from letting the bad guys in. It'll be slow to come out, though, and is mostly intended for people who don't already update their plugins regularly.
While Chrome and Firefox have had the same feature for years, Microsoft's move to plug security leaks is a necessary move. I've been recently covering the spread of dangerous botnets, and security flaws like the one IE just patched are how they start.
If you're running IE with outdated plugins, your browser will now tell you when a site wants to run an outdated plugin. It won't use the plugin without you confirming that you understand that the plugin is out of date.

The problem is, though, that this update won't be rolled out for any computers still running Windows XP. According to NetMarketShare, 25 percent of all computer users are still running XP, which means that 25 percent of all computers are still just as susceptible to botnets as they used to be.
Every security hole that the tech giants don't plug is another unlocked door for hackers to find. Keep your browser updated and - if you want to receive security updates - you'll have to update from XP to a newer version of Windows.
