Anniversary Update is Now on 77 Percent of Windows 10 PCs

It looks like Microsoft has finally worked out the kinks: The Anniversary Update is now installed on 77 percent of Windows 10-based PCs. That’s double the figure from a month ago.

I first reported this surge in Windows Device Stats: Windows 10 Mobile and HP Elite x3 Both Stumble in October. But this bears a closer look, as many readers have asked about the slow deployment of the Anniversary Update.

As you may recall, Microsoft released the Anniversary Update for Windows 10 back in early August, and those who do perform the upgrade will see that the OS has been upgraded to version 1607. For the first few weeks of availability, there was little indication that anything was wrong—a strange freeze issue notwithstanding—but then the problems started. (Microsoft finally fixed those freezes issues weeks later.)

Brad was among the first to report that the Anniversary Update was breaking webcams, an issue I later dubbed Webcamgate. Then, we discovered that plugging in a Kindle could Blue Screen a Windows 10 version 1607 PC.

When it finally became clear that the Anniversary Update wasn’t as bug-free as we had hoped, I called on Microsoft to halt development of Windows and enact a Reliability Initiative. I still feel this is needed.

But then a late August look at Windows device usage stats brought home what was happening with the Anniversary Update:Microsoft had quietly slowed down the deployment of the Windows 10 Anniversary Update specifically because of the problems it had experienced.

At that point, Windows 10 version 1607 was running on just 16.2 percent of Windows 10-based PCs. It September, it nearly doubled, to 35.5 percent. And this month, it did so again, hitting 77 percent. So it’s reasonable to think that the Anniversary Update will indeed be fully deployed by the end of November. That doesn’t mean 100 percent, of course: Some businesses will stick with earlier versions for whatever reason. But it means, I think, that the problems are finally behind us.

    Reliability needs to be a technology industry initiative.  The number of problems lately have been a bit high to me.

    I own many Windows 10 tablets and PC's and all are having some kind of issue. Thinking about downgrading (upgrading) to Windows 7 wherever I can...been like that for the last year, Windows 10 looks good, but is far from reliable. Feels like beta software. Microsoft needs to get their sh*t together. When asked, I never recommend the upgrade to Windows 10.

    "Microsoft finally fixed those freezes issues weeks later"

    I'm still seeing lots of problems.  I upgraded a system yesterday that is used on a metered connection, but was offered the AU once it was connected to my Internet.  It was a tablet.  The AU removed drivers for the Bluetooth and wireless functionality (it's a Broadcom combo chip), and it updated the touch screen driver with an incompatible version that is out of calibration with the screen touch matrix, and the accelerometer driver is showing as compatible, but doesn't work (code 10 - device can't start).  The previous drivers were working fine, and any other time Windows 10 wouldn't even get drivers from Windows Update unless you did a manual check via the Driver tab in Device Manager.

    I have seen numerous issues with AU where post-install updates cause the system to be completely slow or unstable before a necessary reboot too, going so far as where the Start Menu doesn't pop up, or any "modern" apps, like Settings, don't load, or clicking tiles doesn't do anything.  If these updates need a reboot, the user should be prompted to reboot immediately.  Letting a system sit for 2 days in an unstable state, waiting for an optional reboot, is completely unacceptable.

    After a year with Windows 10, I retrograded my PC to Windows 8.1 last night. Significant bugs, unwanted features, and a perception of being at Microsoft's mercy were my chief motivations. Now I will see if 8.1 is as simple and stable as I remember.
