Patch Tuesday for November 2021

To paraphrase butcher Oscar Wilde: the only thing worse than having to install security updates every month is having no security updates at all. If you’re not getting a steady supply of security updates, your software is probably no longer being developed or supported. If you’re just choosing not to install the available updates, you’re asking for trouble. Either is bad, but at least you can do something about the latter.

It’s my duty to inform you that — at least by my count — Microsoft has made available this day approximately twenty-nine updates for Windows, Office, Edge, Visual Studio, Exchange Server, SharePoint, Visual Studio Code, and Windows Server. A total of fifty-five vulnerabilities are fixed by the updates.

The source of this information is Microsoft’s Security Update Guide (SUG). It’s a sluggish and weirdly complicated system to navigate, but does seem to contain the necessary information.

As usual, this month’s collection includes updates for Windows 7, but those updates remain tantalizingly out of reach for most Windows 7 users, because obtaining them involves entering into a special agreement with Microsoft that’s way too expensive for regular folks.

Windows 10 systems get the updates automatically, and Windows 8.1 users — if automatic updates are disabled — should navigate to the Windows Control Panel and Windows Update to install them.

Patch Tuesday for October 2021

Like clockwork, Microsoft has once again provided us with a month’s worth of new security updates.

According to Microsoft’s Security Update Guide, this month there are patches for one hundred and seven vulnerabilties, in Office (2013, 2016, and 2019), Edge, Exchange Server, SharePoint, Visual Studio, System Center, Windows (7, 8.1, 10, and 11) and Windows Server.

As usual, Microsoft is taunting Windows 7 users with updates for that O/S, because most of us regular folks can’t afford them.

Windows 8.1 users — of which I’m one of the very few remaining — can either enable automatic updates, or navigate the Start menu to Windows Update to install available updates manually.

Windows 10 users can still delay updates, though just how long a delay is allowed depends on the flavour of Windows 10 you’re running. Windows 10 Home doesn’t give you much to work with in that respect.

Since Windows 11 isn’t even officially released yet, it’s difficult to predict exactly how updates will be handled for that O/S. However, it’s a safe bet that updates will be shoved down our throats as they are with Windows 10.

Patch Tuesday for September 2021

Summer is winding down, young folks are risking their health going back to school, and anti-vaccination cretins are revealing to the world how incredibly stupid they are by protesting at hospitals.

The good news is that you can easily distract yourself from the bad news for a few minutes by doing something straightforward and comfortable. I’m referring, of course, to installing Microsoft updates on your Windows computers.

If you’re looking for detailed information about the updates being made available by Microsoft today, the best place to start is the official source: the Security Update Guide (SUG). I’m not saying you’ll find it easy to navigate (you likely won’t). But it is the official source.

For those of you not inclined to risk a migraine by looking at the SUG, I’ve done my usual analysis of this month’s offerings, based on data downloaded from the SUG and viewed in a spreadsheet application (any one will do).

This month’s patches address a total of ninety-three security vulnerabilities, in Office, Edge, SharePoint, Visual Studio, Visual Studio Code, Windows Server, Windows 10, Windows 7, and Windows 8.1.

The Windows 7 patches are not available to regular folks, and can only be obtained (legally) by paying Microsoft a large amount of money. Windows 7 users are encouraged to upgrade to, well, I guess Windows 10, which is currently somewhat less terrible than it was when it was released.

Windows 8.1 users — the few of us who remain — have the luxury of deciding whether and when to install updates via Windows Update.

Windows 10 users can only delay updates, and then only if you’re running the Pro (not Home) version.

Patch Tuesday for August 2021

It’s another Patch Tuesday, which these days matters less and less, given that software makers are increasingly forcing updates onto us.

There are still plenty of people running Windows 7 and Windows 8.x: almost 20%, with Windows 10 taking the rest, at close to 80%. That’s according to Statcounter.

Sadly for Windows 7 users, official patches for that O/S are few and far between, with Microsoft only releasing Windows 7 updates to the general public when the vulnerability being addressed is particularly nasty.

That leaves Windows 8.1, for which we continue to receive updates, and for which the process has not changed much since the O/S was introduced in 2013.

The updates

This month, Microsoft is making available updates that address a total of eighty-seven security vulnerabilities in .NET, Office, Edge, SharePoint, Visual Studio, and Windows. That count is based on my interpretation of the official Security Update Guide, and it may differ from totals provided by others, because counting these things is not as simple as it sounds.

If you’re running Windows 10, hold onto your britches as Microsoft installs the new updates remotely on your computer, and hopefully doesn’t break anything this time.

Windows 8.1 users can either enable automatic updates, or head to the Control Panel and fire up Windows Update.

Windows 7 and XP users are basically out of luck. If you are using those systems, I strongly recommend that you don’t also use them for email or web browsing.

Patch Tuesday for July 2021

It could be argued that Microsoft has done us all a favour in making Windows 10’s updates unavoidable. Certainly, as long as nothing goes wrong, it’s less work than futzing around with Windows Update on every computer. And forced updates mean that Windows computers used by less tech-savvy folks stay up to date with security fixes, which makes everyone safer.

It’s also true that increasingly, software and firmware updates for all our devices happen whether we want them or not. By default, mobile devices update themselves. Other electronic equipment, like smart televisions, digital video recorders, amplifiers, and even some network equipment are now doing the same.

But I just can’t shake the feeling of discomfort I get when I think about my computer being messed with at the whim of some Microsoft flunky. Perhaps some day I’ll be more comfortable with it. In the meantime, as long as Microsoft continues to screw up updates, sometimes breaking thousands of computers worldwide, I’ll continue to feel this way.

This month’s Microsoft updates

According to my analysis of the data available from Microsoft’s Security Update Guide, we’ve got updates for Edge, Office, Exchange Server, SharePoint, Visual Studio Code, Windows (7, 8.1, and 10), and Windows Server, addressing a whopping one hundred and thirty-three vulnerabilities in all.

As usual, Windows 10 updates will be installed automatically over the next few days, although you may — depending on your version of Windows 10 — be able to delay them for about a month. You can check for available updates and install them right away by heading to Start > Settings > Update & Security > Windows Update.

Windows 8.1 users also have the option of using automatic updates, but if that’s disabled, you’ll need to go to Start > PC Settings > Update & Recovery > Windows Update.

There seem to be one or two updates that are freely available for all Windows 7 computers, so it’s worth checking Windows Update. When Microsoft releases free updates for Windows 7, you know they’re important. Go to Start > Control Panel > Windows Update to check.

Adobe Updates

Adobe joins the fun again this month, with an updated version of the free and still ubiquitous Adobe Acrobat Reader. Version 2021.005.20058 of Reader includes fixes for thirteen security bugs.

Reader normally updates itself, but you can make sure, by navigating its menu to Help > Check for updates...

Firefox 90

Perhaps coincidentally, there’s also a new version of Firefox today. Firefox 90 addresses nine security vulnerabilities in earlier versions.

By default, Firefox will update itself, but you can encourage it by clicking its ‘hamburger’ menu at the top right, and navigating to Help > About Firefox.

Patch Tuesday for May 2021

Still waiting for the vaccine? Trying to avoid going outside? Well, luckily for you, there are plenty of indoor tasks you can work on, like Netflix binge-watching, exercise, and installing software updates on your Windows computers.

For May 2021, Microsoft is handing us yet another pile of updates, addressing eighty-eight vulnerabilities (by my count) in .NET, Internet Explorer, Office, Edge, Exchange Server, SharePoint, Visual Studio, Skype, and Windows. My analysis is based on data exported from Microsoft’s Security Update Guide.

As usual, Windows 10 users can delay updates but not indefinitely. Windows 8.1 users who don’t have automatic updates enabled need to go to Windows Update to get the updates. Windows 7 users are mostly out of luck, but should check Windows Update anyway, because Microsoft sometimes makes critical update available for all users, not just business and educational users with deep pockets. If you’re still using Windows XP, there are no more updates, and I hope you know what you’re doing.

EdgeDeflector prevents Windows 10 from using Edge

The battle for web browser dominance on the Windows desktop continues, although Google is currently winning. “Google recommends using Chrome” messages seem to appear on every Google-managed web page even if you’re already using Chrome. But while annoying, those messages are arguably reasonable compared with some of Microsoft’s recent tactics.

Microsoft likes to reset certain settings back to their defaults when Windows updates are installed. They’ve been doing this for years, reverting user browser preference to Internet Explorer at every opportunity.

As a result, power users and software developers have been engaged in a tug of war with Microsoft over the default web browser in Windows. In recent years, Microsoft has made it impossible for the default browser to be changed by software, forcing browser makers to instead provide instructions to users on how to make that change. Microsoft can of course claim that this change was made to improve security, and given the prevalance of browser hijackers in past years, it’s difficult to disagree.

With Edge in Windows 10, Microsoft has taken this battle to new extremes. Even if you have another browser selected as the default, some sites and services will always be opened in Edge. To see this in action, click on the taskbar search box. A large panel will open, showing news and weather links. Anything you click here will open in Edge, not in your default browser.

That’s because internally, Windows is using a special protocol called URL:microsoft-edge, which forces the use of Edge for opening web pages that Microsoft has designated as special in some way, despite being ordinary web pages in every sense.

This is of course exactly the sort of behaviour that got Microsoft in trouble in the 1990s: using their dominance in the desktop O/S market to push their own web browser. But these days everyone’s attention seems to be on Google and Facebook, and Microsoft’s browser pushback is being largely ignored.

EdgeDeflector to the rescue

Daniel Aleksandersen’s EdgeDeflector is a small tool that overrides the URL:microsoft-edge protocol’s normal behaviour, forcing it to actually use the web browser you’ve chosen as the default. EdgeDeflector was recently updated to make it more palatable to anti-malware software, which previously flagged the tool as suspicious because of its behaviour.

You’ll have to change this Windows 10 setting manually to make EdgeDeflector work.

Once you install EdgeDeflector, you need to complete its setup with some manual steps. I can confirm that the end result is exactly as advertised: even when clicking news links from the Windows 10 search panel, those links will open in your default browser, not in Edge.

Of course, Microsoft will probably take steps to defeat this useful tool, with the most obvious step being to revert the changes EdgeDeflector has made when Windows 10 is next updated. And so there are no winners in this stupid, never-ending battle.

Patch Tuesday for April 2021

While installing software updates may not be the most fun you can have, at least you can do it indoors and remotely, safe from the pandemic still raging outside.

As usual, the main source of update information from Microsoft is the Security Update Guide (SUG). The SUG is a huge database, and it’s easy to get overwhelmed by the amount of information there. I begin my analysis by downloading this month’s information as a spreadsheet, which when loaded into Excel is much easier to handle.

Estimates of the number of vulnerabilities addressed by this month’s updates vary: by my count, it’s one hundred and eighteen. Other people show the total as ‘over 110’ and 114. Microsoft seems to have embraced a ‘keep them guessing’ strategy, perhaps so that we’ll eventually give up and stop counting, and learn to simply accept what we get without trying to get a handle on it. In psychology, that’s known as learned helplessness, which sounds about right.

This month’s updates include fixes for still-supported versions of Windows, Office, Edge, SharePoint, Visual Studio, and VS Code.

Also this month there are fixes for the rather horrible Microsoft Exchange vulnerabilities that have led to even worse compromises of business, government, and education systems worldwide in recent weeks. That’s great news, but unless you work in one of those environments, you are likely not affected.

Windows 10 users are once again faced with limited options: a) give in to Microsoft and allow updates to be installed on their schedule, risking bad updates; or b) delay updates as long as possible, risking being exposed to security vulnerabilities.

Windows 8.1 users still have an actual choice, since automatic updates can be disabled entirely. In which case you’ll need to run Windows Update manually to get the latest updates.

Windows 7 still occasionally gets updates. Microsoft creates them for enterprise clients, who pay a premium for that service. Non-paying folks don’t usually have access to those updates, although sometimes Microsoft makes individual updates available to all if they are particularly dangerous. Note that Windows 7 still works just fine: you can minimize the security risk of running it by being extremely careful when using email, browsing the web, clicking links, and downloading software.

Windows XP is still being used, but it’s long past receiving any updates, and it’s increasingly unable to run new software. It’s perfectly safe to use if it’s not connected to the Internet, or if it’s only used for specific, limited tasks.

Patch Tuesday for March 2021

It’s another Patch Tuesday, usually referred to by Microsoft as ‘Update Tuesday’. Terminology aside, what it means is a big pile of updates that will be foisted upon most Windows users over the next few days.

Those of us sticking with Windows 8.1 can still review the available updates and install them at our leisure, which can be very satisfying when an update that we defer turns out to cause problems. But Microsoft seems to reserve its major screwups to Windows 10 updates these days (incuding this month’s printing crashes, and the fix for those crashes).

If you’re running Windows 10, you can defer updates for as long as a month… unless you’re running any of the Home versions, in which case the updates are as inevitable as taxes.

This month’s updates address several extremely serious security vulnerabilities in Exchange, Microsoft’s email server software, which ordinary folks are very unlikely to be running.

But the parade also includes updates for the usual offenders: Internet Explorer, Microsoft Edge (both the Chromium-based and original versions), Office (Excel, PowerPoint, SharePoint, Visio), Visual Studio, Visual Studio Code, and of course Windows. One hundred and thirty-one vulnerabilities* are addressed in all.

Microsoft’s Security Update Guide is currently the official source for this information. The SUG has undergone some improvements lately, and it’s gradually getting easier to navigate, which is a relief.

If you’re still running Windows 7, today’s festivities are largely meaningless, though Microsoft does occasionally toss a bone in your direction, in the form of a Windows 7 update normally reserved for those deep of pocket. Microsoft will presumably continue to do this when a flaw is serious enough that witholding the fix would create a public relations problem for the company.

The release notes for today’s updates provide additional details, though they are still sadly somewhat incomplete.

* The vulnerability count varies depending on who’s looking. According to the SANS Internet Storm Center, “This month we got patches for 122 vulnerabilities. Of these, 14 are critical, 5 are being exploited and 2 were previously disclosed.” Brian Krebs says “from Microsoft today…the company released software updates to plug more than 82 security flaws in Windows and other supported software. Ten of these earned Microsoft’s “critical” rating”. Clearly Microsoft’s Security Update Guide still needs work.

Patch Tuesday for February 2021

We’re gradually moving into a world where the software we use every day is maintained remotely, because it runs on or from a remote server, or because it automatically updates itself. This is widely viewed as progress, since the responsibility of protecting everyone from vulnerable software moves away from software users, to software producers. Responsible software producers no longer simply create and sell software, developing and making available updates when necessary; they are taking on the task of deploying those updates to user platforms.

There are drawbacks to this approach. Many people — including myself — are reluctant to cede control of the software we use to faceless corporate drones. We are wary of allowing corporate interests control what we see on our computers. With Windows 10, everything is in place to allow Microsoft to sell advertising space on your computer screen. We shudder to think of the nightmare scenarios resulting from bad (and unavoidable) updates.

For those of us who are resistant to these changes, there are options. Most software that automatically updates itself includes settings to disable auto-updates in favour of manual updates. Notable exceptions are Windows 10, and almost all Google and Adobe software.

There are other problems. Once, every update came with release notes and change logs. Increasingly, the details of changes in updates are not published, and users must simply trust that software producers only ever intend to make things better for us. Sadly, that is not always the case. The Windows desktop client for Spotify is a good example: it’s buggy, unstable, crash-prone, and although it is updated frequently, new versions are not documented in any way. Installing Spotify updates is a game of Russian Roulette, and it’s not optional.

Where do we go from here?

Updates should always be optional. Sure, install them by default, but provide settings to allow users to fully control whether and when updates are installed. At the very least, this would make updates much less stressful for business and educational IT staff. How about providing a free version that automatically updates itself and allows advertising, and a reasonably-priced version that allows control over updates and advertising? I’d be willing to pay a few bucks extra to have that kind of control.

Meanwhile, back to reality

Here in the real world, we’ve got more updates from Microsoft and Adobe, many of which are not optional. Some of these updates are not available for free, and are instead prohibitively expensive (e.g. all updates for Windows 7).

First up it’s Microsoft, with software updates addressing fifty-six vulnerabilities in .NET, Edge, Office, Sharepoint, Visual Studio, VS Code, Windows, and Defender.

If you try to count the number of distinct updates, your numbers will vary, depending on what you’re counting. As such, I will no longer be attempting update counts.

You can wade through the details yourself, using the new, ‘improved’ Security Update Guide. You can also find a summary on the official release notes page for this Patch Tuesday.

Several of this month’s updates address critical vulnerabilities that are being actively exploited. Which of course drives home the point that people really need to update, as soon as possible. Which in turn is a strong argument for forcing those updates. Welcome to the new update hell reality.


Adobe logoAdobe has been installing automatic update mechanisms on your computer for a few years now. As with Google software, this is accomplished using a variety of techniques that are also used by malware: to make sure they are always enabled, to reinstall themselves when removed, and to remain hidden as much as possible. While it is possible to remove or disable these update mechanisms, doing so is an exercise in frustration, because they will return, sometimes in a form that’s even more difficult to remove. The only real solution is to avoid using such software.

If you’ve ever opened a PDF file on your computer, there’s a good chance that it opened in Adobe’s free Acrobat Reader. In which case that software is updating itself automatically, using a system service called Adobe Acrobat Update Service.

Adobe released a new version of Reader on February 9: 2021.001.20135. This new version addresses at least twenty-three security vulnerabilities in earlier versions. Since it’s difficult to know exactly when automatic updates will occur, it’s a good idea to check. On Reader’s menu, navigate to Help > About Adobe Acrobat Reader DC. If your version is out of date, select Help > Check for Updates on Reader’s menu to install the new version.
