MS-DEFCON 5: Get patched now
Yes, you read that correctly.
I’ve been posting MS-DEFCON warnings for seven (eight?) years, and I can’t recall having two MS-DEFCON 5 months in a row. This is a first, and a great time to get caught up on all outstanding Microsoft patches.
There were just a few minor problems with the June 2015 patches (the whole crop of them, not just Black Tuesday), and May 2015 worked out well, too.
If you don’t mind having a Windows 10 advertisement stuck in your system tray — it won’t jump up and bite you — just go ahead and install everything that’s offered. If the thought of an obnoxious Microsoft ad on your machine bothers you, skip KB 3035583 and KB 3022345.
For the second month in a row, I’m moving all the way down to MS-DEFCON 5: All’s clear. Patch while it’s safe.
The usual admonition applies: Use Windows Update, DON’T CHECK ANY BOXES THAT AREN’T CHECKED, reboot after you patch, and then run Windows Update one more time to see if there’s anything lurking. When you’re done, make sure you have Automatic Update turned off. I always install Windows Defender/Microsoft Security Essentials updates as soon as they’re available – same with spam filter updates. I never install drivers from Windows Update (in the rare case where I can actually see a problem with a driver, I go to the manufacturer’s web site and download it from the original source).
