Microsoft Admits Disabling Anti-Virus Software For Windows 10 Users (bbc.com)

An anonymous reader quotes a report from the BBC: Microsoft has admitted that it does temporarily disable anti-virus software on Windows PCs, following an competition complaint to the European Commission by a security company. In early June, Kaspersky Lab filed the complaint against Microsoft. The security company claims the software giant is abusing its market dominance by steering users to its own anti-virus software. Microsoft says it implemented defenses to keep Windows 10 users secure. In an extensive blog post that does not directly address Kaspersky or its claims, Microsoft says it bundles the Windows Defender Antivirus with Windows 10 to ensure that every single device is protected from viruses and malware. To combat the 300,000 new malware samples being created and spread every day, Microsoft says that it works together with external anti-virus partners. The technology giant estimates that about 95% of Windows 10 PCs were using anti-virus software that was already compatible with the latest Windows 10 Creators Update. For the applications that were not compatible, Microsoft built a feature that lets users update their PCs and then reinstall a new version of the anti-virus software. "To do this, we first temporarily disabled some parts of the AV software when the update began. We did this work in partnership with the AV partner to specify which versions of their software are compatible and where to direct customers after updating," writes Rob Lefferts, a partner director of the Windows and Devices group in enterprise and security at Microsoft.

    MS certainly does care about compatibility, it's why the x86 version of Windows is still produced. (You can still run 36-year-old programs just by double-clicking them on 32-bit Windows - and, of course, it still runs legacy 16-bit Windows programs too).

    Your mistake was doing an in-place upgrade to Windows 10. You should have done a fresh install, then reinstalled your 31 mission critical programs thereafter.

    (Disclaimer: I work in a school and have had to get all sorts of legacy stuff working under Windows 10. The only thing that wouldn't work whatsoever was an old ID badge printer which used an obscure way of interacting with its Windows 2000-era driver. The rest of the stuff, including such delights as old laser cutters connected by serial ports, works just fine. Yes, you may have to fiddle with settings and even the registry in some cases, but the vast majority of stuff out there can be made to work with little or no effort.)

      There was an Avast update that fixed the issue within around 48 hours, but it was still a fairly major headache in the interim. It's not entirely unreasonable of MS to have acted to prevent a repeat of this.

    Why are you comparing a stationary appliance without external interface to a computer program? If that's your comparison then it's worth pointing out that Windows XP still works. It didn't magically vapourise with the release of Windows Vista, 7, 8, or 10.

    Now if on the other hand you have a security issue with the fact that your Windows XP machine is network based, or you have a major obsolescence issue that could take out the machine at any time, can you really say it still "just works"? If the camera on your 9 year old smartphone breaks does it still just work? What if that camera was actually "mission critical"?

    If Office macros are a particularly common infection vector, then the fault lies with the developer of Office (Microsoft), not the developer of Windows (Microsoft).

    The common theme here is obvious, but what is uncommon is also important. Office macros are powerful by design. That is VBA inside, and while VBA was always easily ridiculed for performance reason and for the fact that its a BASIC, the criticism was never to my knowledge its capability. Hell VBA code can load a DLL and call its functions. Full stop.

    Powershell is also designed to be powerful. Just another variation on the command-shell theme.

    I really dont want the OS locking down file associations, nor do I want to be prevented in any way from installing "unapproved" software, therefore the OS isnt at fault here. Its the developer of Office for somehow making it too easy for untrusted VBA code to be executed.

The closest software analogy to this is the Operating System, certainly not the lowly Virus Scanner.

    In order to understand why Microsoft may have logically chosen to do that for their CUSTOMERS, you would have to understand drivers. All pro-active virus scanning software sits in the driver stack. They intercept operating system calls to try to determine whether you're about to run i_h4x0r3d_j00.exe and prevent that from happening. Microsoft drivers also happen to sit in the same driver stack along with everyone else's. They all sit at a particular "altitude" in that driver stack. Some versions of software that are signed drivers that sit in this stack interfere with other drivers in that stack. Microsoft most likely proactively decided that instead of being like "I can't update X because of your crappy third party software that doesn't work right" to temporarily disable it, so they could apply the updates and then re-enable it or their product afterwards.

    Now I realize that doesn't make for as sensational news story as something that implies Microsoft purposefully disabling other competitors software but it's more likely that something like what I said is the case. I hate to disappoint you. Cheers!

The Mac was kept on OS9 because they wouldn't support it in anything later, and the Windows updates killed the codec. All of this was because of hissyfits between the developer and Apple/Microsoft.
