  • MS-DEFCON 3: Get the March 2020 patches installed

    Posted on April 1st, 2020 at 09:32 woody Comment on the AskWoody Lounge

    It’s been a strange patching month, with a Patch Tuesday, a Patch Thursday, the usual buggy “optional, non-security C/D Week” patch, a bonus fix for a bug introduced in late February’s patch, and a warning (with no patch) about yet another bad-font fallibility.

    There are several known bugs, but they all have reasonably well-known workarounds.

    Anyway, now’s a good time to make sure you have the March patches installed. Full instructions in Computerworld Woody on Windows.

  • Microsoft posts a fix for the VPN-related dropped internet connection bug

    Posted on March 30th, 2020 at 16:22 woody Comment on the AskWoody Lounge

    That was quick.

    Four days ago, Microsoft posted an acknowledgment of an unusual bug that’s contained in every Windows patch since the “optional, non-security, C/D Week” patch for February.

    AskWoody poster @jayinalaska describes it thusly:

    Yesterday, I installed the Pulse Secure application on my work PC so I could VPN into a sensitive work network. As soon as I make a connection in the Pulse Secure application, I get the “Limited network” (no internet) warning. I can verify the warning is accurate. During one VPN session, I had Google Drive open in a browser at the same time and was warned I didn’t have a connection any more. As soon as I disconnect from the VPN, the network comes back to normal.

    Here’s the announcement:

    Out-of-band optional update is available for internet connectivity issues on devices with manual or auto-configured proxies including VPNs

    An out-of-band optional update is now available on the Microsoft Update Catalog to address a known issue whereby devices using a proxy, especially those using a virtual private network (VPN), might show limited or no internet connection status.

    We recommend you only install this optional update if you are affected by this issue. For more information, see the known issues section for your version of Windows 10 or see the links below.

    You can find all 20 of the patches in the Microsoft Update Catalog.

  • Yet another bug in this month’s Windows patches: Proxy bug knocks out some internet connections

    Posted on March 27th, 2020 at 10:40 woody Comment on the AskWoody Lounge

    There’s a reason why I wait before recommending that you install patches, yes?

    News came yesterday afternoon that every.single.Windows.patch released since the “optional, non-security, C/D Week” patch at the end of February introduces a newly acknowledge bug:

    Devices using a proxy might show limited or no internet connection status

    Devices using a manual or auto-configured proxy, especially with a virtual private network (VPN), might show limited or no internet connection status in the Network Connectivity Status Indicator (NCSI) in the notification area.  This might happen when connected or disconnected to a VPN or after changing state between the two. Devices with this issue, might also have issues reaching the internet using applications that use WinHTTP or WinInet. Examples of apps that might be affected on devices in this state are as follows but not limited to Microsoft Teams, Microsoft Office, Office365, Outlook, Internet Explorer 11, and some version of Microsoft Edge.

    According to Microsoft, this bug was introduced in the “optional, non-security, C/D Week” patch for February. If you’re running Win10 1903 or 1909, that’s KB 4535996.

    English translation: If you’ve installed any of the Windows updates since last February’s switch to MS-DEFCON 3, you’ve been bitten.

    There have been three bad patches: The usual Patch Tuesday cumulative update, KB 4540673 for Win10 1903 and 1909; the emergency, notoriously buggy cumulative update KB 4551762 that was supposed to fix the SMBv3 bug; and KB 4541335, which is the next-to- penultimate “optional, non-security C/D Week” patch for Win10 1903 and 1909. [Correction: We’ll have optional, non-security, C/D Week patches in both April and May. Oh boy.]

    If you’re using some other version of Windows, the KB numbers will be different.

    Microsoft says “We are working on a resolution and are targeting a Microsoft Catalog only release of an out-of-band update to resolve this issue by early April.” English translation: If you were trusting enough to install any Windows patches since Feb’s switch to MS-DEFCON 3, and you hit a problem connecting to the internet, try rolling back the patch.Or “You might be able to mitigate the issue by restarting your device.”

    The problem is odd enough that I haven’t seen it in action. But if your internet connection keeps dropping, you should definitely look at rolling back the buggy update(s). There’s nothing in those patches that needs to be installed, like, right now.

    And fer heaven’s sake, don’t voluntarily put your machine in the “cannon fodder” category. Sit back, relax, wait for the problems to appear. And watch the MS-DEFCON level.

  • Reported problem with the latest Windows Defender “Unexpected error”

    Posted on March 25th, 2020 at 09:35 woody Comment on the AskWoody Lounge

    Oh boy. You know that unpublicized Windows Defender patch that fixed the “Items skipped during scan” bug?

    There are two reports on Reddit already about bugs in the new version. Per u/K1Xaviesta:

    Hi I just updated my windows 10 and I got a notification that the windows defender is off and when I go to Windows Security and Virus & threat protection to turn it on it says “Unexpected error. Sorry, we ran into a problem. Please try again.”

    Are you seeing similar problems after installing  KB4052623?

  • Microsoft pauses non-security patches

    Posted on March 25th, 2020 at 09:10 woody Comment on the AskWoody Lounge

    Microsoft says it won’t be pushing any new non-security patches (although they just pushed one about an hour ago).

    We have been evaluating the public health situation, and we understand this is impacting our customers. In response to these challenges we are prioritizing our focus on security updates. Starting in May 2020, we are pausing all optional non-security releases (C and D updates) for all supported versions of Windows client and server products (Windows 10, version 1909 down through Windows Server 2008 SP2).

    There is no change to the monthly security updates (B release – Update Tuesday); these will continue as planned to ensure business continuity and to keep our customers protected and productive.

    Perhaps you can read the tea leaves better than I can. Is Microsoft saying that, for the foreseeable future, they’re only going to be releasing security patches to Win10? The announcement doesn’t quite say that – and today’s patch is a counterexample – but it certainly hints in that direction.

    If so, bravo!

    UPDATE: Mary Jo Foley has a recap. But it still doesn’t answer my fundamental question. I think. Will we stop getting non-security patches altogether?

    ANOTHER UPDATE: I put together my concerns in this post for Computerworld Woody on Windows. I sure wish MS would learn to speak clearly….

    P.S. Why, oh why, isn’t Microsoft using an Insider ring for non-security patches on production versions of Windows?

    AN OFFICIAL UPDATE: On Twitter, a few minutes ago, the official @WindowsUpdate account said:

    That sounds right to me.

  • Microsoft quietly fixes the “Items skipped during scan” Windows Defender bug

    Posted on March 25th, 2020 at 07:12 woody Comment on the AskWoody Lounge

    Report out this morning from Günter Born: It appears as if Microsoft has released a new version of Windows Defender that fixes the “Items skipped during scan” bug I talked about in Computerworld yesterday.

    It’s listed as KB 4052623. You should get it automatically in the next day or two (Windows Defender updates aren’t controlled by the usual Windows Update settings). It’s also available in the Microsoft Catalog.

  • Microsoft releases the “optional, non-security, C/D Week” patch for Win10 version 1903 and 1909

    Posted on March 24th, 2020 at 12:19 woody Comment on the AskWoody Lounge

    It’s KB 4541335 – covers lots of little fixes.

    As usual, you won’t get it unless you go into Settings > Update & Security, then click the link to Download and install now.

    Also as usual, you don’t want it. Let the other WFHers try it first.

  • March 2020 Windows and Office patch status

    Posted on March 24th, 2020 at 11:01 woody Comment on the AskWoody Lounge

    What a strange month.

    Two sky-is-falling security holes with unconscionable “Microsoft warns meeeeeeelions of Windows users that they’re vulnerable” headlines. (Spoiler: The sky isn’t falling.)

    A bogus warning about skipped scans.

    And lots of people working from home who really don’t need another unstable round of updates or upgrades.

    Details in Computerworld Woody on Windows.

    We’re still on MS-DEFCON 2. There’s no pressing reason to install this month’s patches. Yet.
