Patch Tuesday

A couple of years ago, when I started leaving my computer on all the time, I noticed that my computer would be turned off in the morning. Since I knew I hadn’t turned it off, I turned to the most likely culprit. I asked Chris why he had turned off my machine without letting me know so that I could save all of my stuff first!

That’s when he told me about Patch Tuesday. Microsoft has been sending out monthly updates, generally on the second Tuesday of each month, for a long time. They formalized this process in October 2003. According to this article:

“Microsoft has a pattern of releasing a larger number of updates in even-numbered months, and fewer in odd-numbered months.[7][8][9] Minor updates are also released outside Patch Tuesday. Daily updates consist of malware database refreshes for Windows Defender and Microsoft Security Essentials. Sometimes there is an extraordinary Patch Tuesday, two weeks after the regular Patch Tuesday. Some updates could be released at any time.”

Although Microsoft has changed the name to “Update Tuesday”, the new name hasn’t gained wide acceptance in technical communities. The patches generally include code to update your Operating System to fix known bugs and to plug up any vulnerabilities from malware.

Most people notice a “Patch Wednesday” more than Patch Tuesday. Since the updates are generally installed overnight, you might be prompted to turn off your machine on Wednesday morning to finish the installation. And, occasionally you’ll experience glitches with your machine on Wednesday.

Patch Wednesday is also called “Crash Wednesday” since your computer is more likely to crash after the Patch Tuesday updates have been installed. We frequently hear from customers on “Patch Wednesday” who tell us that all of a sudden they can’t print, or their internet isn’t working. Lots of times the fix is as easy as turning off the machine and turning it back on again. But sometimes they need us to reinstall drivers or re-configure their router.

It’s also been called “Exploit Wednesday” since there have been times when the Microsoft patches have left machines more vulnerable to malware. In fact, a recent blog by UK engineer “Zeros & Ones” is a bit of a rant about the whole Patch Tuesday process.

“Security is not ‘my bag’ as such – but the people at Microsoft seem to be in a fantastic situation where security issues only arise on Tuesdays. How do they do they seem to manage to get the ‘bad man’ on side?”

  1. Just an observation after 40 years of computer servicing. Anyone who installs updates or lets Microsoft install updates as soon as they are available is asking for trouble. The folks that update ASAP are the ones that discover all the problems first.
    I let Microsoft tell me when updates are available and then usually days or a week later I will download and install on my schedule. By then they have fixed most of the problems.
    I also would also recommend not leaving your PC on all the time, especially if you have a PC not on batteries. With all the power outages and glitches that we get in the mountains, It is just makes sense.
