  • A change to Alerts!

    Alert Logo

    Our MS-DEFCON system has proven extremely popular. It’s the reason the banner on our home page is so prominent.

    Early in 2021, we decided to post an abbreviated version of MS-DEFCON alert newsletters in our blog, reserving the full alert for Plus edition members. We’ve been pleased that this change met with general acceptance, but a review of our alerts for 2021 has shown that the difference between our blog post and the full alert is minimal. Therefore, I’ve decided to make a change.

    We publish two kinds of alerts, one for a changed MS-DEFCON level and one for other types of information. Henceforth, all MS-DEFCON alerts will be available to anyone visiting the site. Other alerts will continue as an exclusive benefit of Plus membership, as will emailed alerts and text message alerts.

    I’m happy to bring the MS-DEFCON coverage to a wider audience. It’s my contribution to promoting safe and sensible patching strategies.

  • MS-DEFCON 2: October updates right around the corner

    ISSUE 18.38.1 • 2021-10-08

    MS-DEFCON 2

    By Susan Bradley

    Enjoy the fall season — take a break from patching!

    With the October updates bearing down upon us, it’s time to take a break. Wrap up patching and updating from September, and prepare your PC to delay the upcoming patches.

    For those of you still on Windows 10 2004, this is an excellent time to upgrade to 21H1 and let it settle in. As for Windows 10 21H2, we still don’t have a definite date.

    Windows 10 will be fully supported until 2025, but it’s still unclear whether Microsoft will be switching to an annual feature-release schedule, as with Windows 11, or keeping the twice-per-year cadence we’ve had for the past five years.

    Consumer and home users

    Based on the information I have now, I will probably sound the all-clear for consumers to install this round of updates on or after October 26. Go into Start, Settings, Update and Security, and Advanced options. In the Pause Updates section, pick October 26 from the drop-down menu.

    If you’ve installed the September updates for Windows 10 2004, 20H2, or 21H1, including KB5005565, you can turn your print spooler service back on and use your printer normally — Microsoft has finally fixed its Print Nightmare bugs. It’s safe to turn it on and leave it on (we hope).

    Business users

    For businesses, I’ll urge you to unofficially shoot for deploying updates a week earlier on October 19. Every time I’ve tried to urge businesses to patch earlier than consumers, we’ve hit side effects and needed to wait for workarounds.

    This is also the time to be testing — but not deploying — Windows 11. Microsoft started releasing Windows 11 as it became Tuesday, October 5, in each time zone around the world. All the tools that help us control, patch, and deploy Windows 10 will also be used to control, patch, and deploy Windows 11. Microsoft is releasing much of its Windows 11 content and will be updating it as more information comes out. Tuesday marked the start of the 36-month servicing-support lifecycle for Enterprise and Education editions of Windows 11. The Home, Pro, Pro for Workstations, and Pro for Education editions of Windows 11 will receive 24 months of servicing support. But I see no need to rush into Windows 11 — it’s a time to watch for side effects and issues.

  • MS-DEFCON 4: All clear for consumers, less so for businesses

    AskWoody Plus Alert Logo
    ISSUE 18.32.1 • 2021-08-25

    MS-DEFCON 4

    By Susan Bradley

    This month has been a bit bumpy for business users needing to print.

    This month’s change to a technology called “Point and Print” has triggered side effects for information technology professionals who deployed workstations without administrator rights.

    Although I’m reluctantly recommending installing these updates, because you need to be protected from all the other vulnerabilities this month, I must acknowledge that even after you patch, you still won’t be protected from printer vulnerabilities. There is yet another Print Spooler issue out there. Right now, the only way you can protect yourself from the remote Print Spooler attack described by CVE-2021-36958 is to keep your Print Spooler service disabled unless it is absolutely needed.

    Consumer and home users

    Install the August updates. In a change to my past update recommendations regarding .NET, I now recommend installing the .NET updates as well. For the last year, I’ve not experienced any side effects with the nonsecurity .NET updates and feel confident about their safety.

    I’ve also not been tracking any side effects with Chromebook 92 after its release on August 2. Unlike last month, there’s been no need to roll back this version.

    Business users

    For those of you in charge of business patching, there’s no good resolution for the side effects of the August updates, not to mention the risks of the unpatched Print Spooler vulnerability. If you deploy print drivers using group policy and your users do not have administrator rights, they are being prompted to install a printer-driver update even though the printer driver has not changed — the only thing that has occurred is that the patch was installed. You can deploy a registry key to

    HKLM\Software\Policies\Microsoft\Windows NT\Printers\PointAndPrint

    with the name RestrictDriverInstallationToAdministrators and a DWord value of 0, but unfortunately, this opens up your workstations to attack. It’s not a good solution.

    The root cause appears to be v3 versions of printer drivers. In the short term, I recommend several possible solutions.

    • Temporarily allow administrator rights via group policy to allow your end users to install the updated print driver, and then revert them back to non administrator rights.
    • Use the registry key workaround (above) that will allow printer drivers to be installed, with full knowledge that this opens your machine up to attack.
    • Review the printer drivers you have installed and ensure that they are v4 and not earlier versions.

  • MS-DEFCON 2: Get ready for battle stations

    AskWoody Plus Alert Logo
    ISSUE 18.29.1 • 2021-08-06

    MS-DEFCON 2

    By Susan Bradley

    The annual security conference known as Black Hat is in the bag, and we are (well, I am) anxiously awaiting the next bugs that will rear their heads, based on the headlines that came out of the conference.

    Topics like Print Spooler bugs, Mac privacy bugs, and encryption platform attacks were just some of the headline topics that I expect to result in a new wave of patches — not just for Windows, but for almost every device.

    Consumer and home users

    In preparation for Patch Tuesday, I recommend that you take the usual actions to defer, pause, block, and just avoid updates for the operating system and Office apps. I suggest deferring until at least August 24. As always, we’ll keep an eye on side effects and issues.

    Remember, there are several ways to defer updates. The easiest way, in my opinion, is to click on Settings, Windows Update, Advanced Options, and then choose August 24 in the “Pause updates” section. When that clock runs out, updates will install automatically. Alternatively, use WuMgr to selectively install updates. Of course, as I always recommend, take the time to back up your system.

    Chromebooks should have been updated to 92.0.4515.130. It includes an improved version of Zoom as well as several other useful bug fixes.

    The Apple camp is still in beta testing mode on Monterey, and it’s anticipated that the release will be in September. In the meantime, you can keep up with the latest news on that beta in our forums.

    Business users

    What concerns me most is the “Microsoft Won’t-Fix-List (July 2021 Edition)” that a security researcher started in July of 2021 to document all the items that Microsoft hadn’t fixed by the end of July. Note that this list does not include all “won’t fix” items, just the ones that occurred during the month of July.

    I’m hoping that we see more of these issues fixed, especially those related to Print Spooler bugs. Those bugs keep me nervous about having the Print Spooler service enabled. I continue to recommend that you enable the Print Spooler service only on those computers and servers that absolutely need it for business operations.

  • MS-DEFCON 4: Get those June updates installed

    ISSUE 18.23.1 • 2021-06-24
    MS-DEFCON 4: Get those June updates installed

    MS-DEFCON 4

    By Susan Bradley

    It’s time to deal with “News and Interests.”

    Consumer and home users

    If you’ve been procrastinating with the June updates so you didn’t have to deal with the new “News and Interests” feature and its side effects, the time has come.

    Microsoft has released KB5003698 to fix issues with blurry images in 1909 for Enterprise. Windows 10 2004/20H2 and 21H1 received KB5003690 to fix the blurry text on the News and Interests button for some screen resolutions. KB5003690 also fixes a problem with search box graphics on the Windows taskbar, which occurs if you right-click the taskbar and turn off News and Interests. This graphics issue is especially visible when using dark mode. If it is a problem for you, install this optional update.

    There are other issues to work out, such as interactions with the desktop if you are using Classic Shell or other menu programs. AskWoody readers have noted cases in which sign in to customize the news selections did not work. If you have problems with the News and interests feature, try setting it to icons only instead of icons and text.

    For Office updates, open up any Office software application, click on File, Account, Office Updates, and enable updates. Then click on Update Now to trigger their installation.

    Business users

    This month’s releases showcase that timing is everything. If you apply updates to workstations before applying them to servers and then attempt to use remote event-log tools, you will find that you cannot access the event logs. As noted by Microsoft, affected apps are using certain legacy Event Logging APIs. Ensure that you apply the updates for both workstations and servers before attempting to use such software.

  • MS-DEFCON 2: Defer Windows & Office updates to June 24

    AskWoody Plus Alert Logo
    ISSUE 18.20.1 • 2021-06-04
    MS-DEFCON Level 2

    By Susan Bradley

    Consumer and home users

    Hopefully, you’ve taken the time to get the May updates installed.

    Before next Tuesday, be sure you are comfortable with your methodology for deferring updates. For Windows updates, I’m still a fan of the method I call “pick the date.” Go to Settings, then to Update and Security; click on Advanced options, and select Pause updates. Then use the Select date drop-down to choose the date when you’d like updates to resume. I’m suggesting June 24.

    Note that the News and Interests notification will be fully enabled in your task bar this month.

    For Office updates, open up any Office application, click on File, Office Account, Office Updates; choose Disable Updates. You can resume updates later in the month. While you have Office updates disabled, avoid opening macro-enabled files as a defense against potential ransomware threats.

    Business users

    Ransomware has been a big topic in the news this month. While doing your patch testing, continue to educate your end users about the dangers posed by simple tasks done carelessly — opening emails, transferring files, clicking on links, etc. Greater danger requires greater vigilance.

  • MS-DEFCON 4: It’s quiet out there

    AskWoody Plus Alert Logo
    ISSUE 18.19.1 • 2021-05-27
    MS-DEFCON Level 4

    By Susan Bradley

    This month has been relatively quiet with respect to patching side effects. It’s now time to install the May updates.

    Consumer and home users

    Most of the issues and complaints have not been about the May update. Instead, there has been dissatisfaction with a new feature called News and Interests. As this feature rolls out, more and more people are asking how to remove it. I have provided a registry update file that will automatically disable News and Interests. The only known side effect is audio issues in some machines; these can be bypassed by using stereo settings.

    More details will be provided in my upcoming Patch Watch article.

    Business users

    For small businesses that still have an on-premises Exchange email server, make sure you install this month’s Exchange patches, as described in KB 5003435.

    Note that some users reported issues if they had manually removed the new version of Edge, proving once again that Microsoft doesn’t test the edge cases (pun intended).

  • MS-DEFCON 2: Pause on patching

    AskWoody Plus Alert Logo
    ISSUE 18.17.1 • 2021-05-10
    Susan Bradley

    By Susan Bradley

    It’s time for both business users and consumer or home users to pause Windows updates.

    Accordingly, I’m changing the AskWoody MS-DEFCON level to 2. Patch reliability is unclear. Unless you have an immediate, pressing need to install a specific patch, don’t do it.

    Consumer and home users

    If you are a home/consumer user, I recommend two actions to ensure you do not get inadvertent updates. First, select Start, Settings, Network & Internet, and then Wi-Fi or Ethernet (whichever connection you are using). Next, click Manage known networks; click on the network that you use, click Properties, and turn on Set as metered connection. This “tricks” the computer into thinking that your Internet connection is not unlimited (i.e., you might incur charges) and thus will download patches only after you approve the process.

    The second action is picking a deferral date after May 11, when Microsoft will push out the next Patch Tuesday security releases. Click on Start, Settings, Update & Security; then click on Advanced Options. Pick a date far enough in the future to give you comfort. I always wait at least a week, usually more. I’ll be re-evaluating the update situation closer to the end of the month, but for now choosing May 28 should be safe enough.

    For those of you with an Office click-to-run (CTR) edition, I strongly recommend that you change to the semiannual channel rather than the monthly one because it will keep you from the Autocomplete bug.

    Business users

    Coming this month in the May Security releases, Microsoft will be including a new “News and Interests” taskbar item featuring items of interest to your users. Remember, if you want to proactively block it, there are registry keys and group policy to control it.

  • MS-DEFCON 2 – Deferring the April Updates

    AskWoody Plus Alert Logo
    ISSUE 18.12.1 • 2021-04-11

    Susan Bradley

    By Susan Bradley

    Brace yourself for April updates

    It’s the time of the month to pause for updates. You will recall that the March updates were very disruptive and many of you decided to not install that round. The April releases are cumulative so you won’t have to go back and install the March updates. Instead, we’ll take a long pause to see what April brings.

    If you are a home/consumer user, I recommend two actions to ensure you do not get inadvertent updates. First, select Start, Settings, Network & Internet, and then Wi-Fi or Ethernet (whichever connection you are using). Next click Manage known networks, click on the network that you use, click Properties and turn on Set as metered connection. This “tricks” the computer into thinking that your Internet connection is not unlimited (i.e., you might incur charges) and thus will only download patches once you approve the process.

    The second action is picking a deferral date after April 13, when the next Patch Tuesday security releases will be pushed out by Microsoft. Click on Start, Settings, Update & Security, then click on Advanced Options. Pick a date far enough in the future to give you comfort. I always wait at least a week, usually more. I’ll be reevaluating the update situation closer to the end of the month, but for now choosing April 30 should be safe enough.

    Remember: For those of you running Windows 10 1909, support is coming to an end. After May 11, 2021, 1909 will not receive security updates. In accordance with prior advice, update to 20H2; 21H1 is just around the corner.
