Microsoft Has Broken Millions Of Webcams With Windows 10 Anniversary Update (thurrott.com)

The Anniversary Update which Microsoft rolled out to Windows 10 users earlier this month has broken millions of webcams, the company said on Friday. The problem is that after installing the update, the company added, Windows no longer allows USB webcams to use MJPEG or H264 encoding processes, and only supports YUY2 encoding. Microsoft says it introduced the changes to prevent an issue that was resulting in duplication of encoding the stream (poor performance). If you're facing the issue, there's a workaround (via Thurrott.com): Rafael has figured out a workaround that should hopefully stop the freezing issue; if you are comfortable tweaking the registry, make this change. HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform, add DWORD "EnableFrameServerMode" and set to 0

      My wife's new notebook lost Miracast capability with the 8/12/16 Windows Security update. Miracast worked fine out of the box for several months, suddenly stopped for no apparent reason, checked update logs, 8/12/16 was the latest, unapplied it, Miracast is back. Windows 10 Home - no (easy) options to suppress automatic updates. Hurray for progress. They killed the Atom based Netbook / Nettop generation of PCs with updates to XP, too.

      They fixed a performance issue by taking away a feature that millions of people use.

      If I did that at my job, I'd probably be fired.

      I haven't seen an update since I disabled the "Windows Update" service and set its "Action on failure" property to "No action". (note: not sure of the exact wording regarding action on failure, but you'll see it if you go to Computer Management, select Services, scroll down to Windows Update, right-click and select Properties; I believe it's in the right-most tab.)

    No, seriously, thanks, developers. For always being "evergreen," for deciding that end users should no longer have the right to accept or refuse individual "upgrades," and for always being agile.

    I mean, I get it. I get that you don't want to support more than one platform or configuration at any given moment in time. It's not fun having to regression test against a billion third-party devices, and it's not cool to QA things that work fine on your machine - and in a DevOps world, you don't have to - but please, find someone in your office with a little grey in his beard, and ask them, just once, about writing software with the user's needs in mind, not just your manager's desire to cut support costs.

    It wasn't that long ago that software that worked, continued to work until the end user broke it by changing something. Now the users aren't breaking things -- but you are. Why?

    Would it seriously be too much to ask if, in exchange for no longer being able to receive technical support (because technically, a working configuration that isn't "the newest version" is unsupported in this brave new world Nadella's created for us), users be permitted to not change already-working configurations?

      The nasty trick in this case is that they shouldn't have had to test against a zillion awful webcams to know that they had a problem.

      The USB Video Class Spec and Microsoft's own driver for it defines support for both uncompressed and compressed video output; and for programs to negotiate with a UVC device to change video parameters.

      The extra abstraction layer they added between the driver and the applications only supports one uncompressed format; and breaks if you try to negotiate for something different. That's not a weirdo edge case with somebody's ghastly rev. A product that never should have made it out the door; that's "break a substantial portion of a spec we used to support and hope everything turns out for the best". Not good.

      Mgmt: There's an issue with duplication of encoding when using USB web cams. It needs to be fixed.

      Developer: Sure, not a problem. Let me look at the issue.

      Developer: Problem solved!

      Mgmt: That was fast! How did you do it?

      Developer: I removed access to the parts causing the problem.

    There was no performance issue - the problem was that multiple applications could not access the camera at once, and it was important to fix this.
    Quoting:
    " It was important for us to enable concurrent camera access, so Windows Hello, Microsoft Hololens and other products and features could reliably assume that the camera would be available at any given time, regardless of what other applications may be accessing it. "

  9. My Win10 horror story by Tablizer · · Score: 4, Funny

    Older versions of Windows have a "Favorites" sub-menu on the left side of File Explorer. When I had to convert to Windows 10 at work, the "Favorites" links were automatically migrated into something called the "Quick Access" (QA) menu. So far so good: it converted old stuff into its new convention.

    However, "Favorites" used alias names, similar to naming a Windows Shortcut. But QA doesn't (at least not by default). Instead, QA uses the last actual folder name in the path as the displayed title.

    I thought QA simply rudely renamed my Favorites titles, so I right-clicked on them to "fix" the titles. Turns out I wasn't looking at an alias, but the live folder name.

    The result is I inadvertently renamed network folders used by hundreds of employees! Of course trouble-tickets started popping up like pop-corn. I put two and two together, and quickly renamed them back, and then went for a walk to dry off the sweat.

  10. Use case starvation by mveloso · · Score: 3, Insightful

    The basic problem was that the developers at Microsoft don't understand who uses their OS and why. They had 5 use cases when they were developing their new feature, but forgot about the 50,000 use cases that already exist, unknown to the development staff.

    "We changed an API's behavior because of this new feature that nobody cares about, which broke almost every imaging device attached to the OS" reeks of poor engineering management.

    Another reason why Windows is not ready for the desktop.

    Grandma runs desktop Linux just fine.

    This is rather insightful. I may be a Linux fan but there was a time when I would have readily admitted Grandma would have an easier time with Windows than with Linux (assuming someone competently preinstalled one or the other for her use). This surely started to change with the unusability of Windows 8 and now, with all the Windows 10 issues, I would not like to be on the receiving end of Grandma's support calls.

    My wife (who is a grandma, by the way) uses a Linux distro that I installed and maintain for her (maintenance means installing updates once in a while). She neither knows nor cares that it's Linux and not Windows. It "just works" for her rather basic needs, and if she some day requires more advanced features, they're all available.
