Microsoft today released fixes to plug at least 55 security holes in its Windows operating systems and other software.

Kevin Breen from Immersive Labs said the fact that this one is just 0.2 points away from a perfect 10 CVSS score should be enough to identify just how important it is to patch.

"This patch fixes a vulnerability that could allow an attacker to disclose the contents of encrypted wireless packets on an affected system," he said.

Microsoft also patched four more security holes its Exchange Server corporate email platform, which recently was besieged by attacks on four other zero-day Exchange flaws that resulted in hundreds of thousands of servers worldwide getting hacked.

As always, it's a good idea for Windows users to get in the habit of updating at least once a month, but for regular users it's usually safe to wait a few days until after the patches are released, so that Microsoft has time to iron out any kinks in the new armor.

If you wish to ensure Windows has been set to pause updating so you can back up your files and/or system before the operating system decides to reboot and install patches on its own schedule, see this guide.
