I’m no longer in the Windows 10 Insider Preview program, but I still see Microsoft’s preview build announcements. The latest is for build 14926.

The announcement for build 14926 reveals yet another reminder that we are just pawns in Microsoft’s overall strategy. Anyone participating in the Preview program must allow Microsoft to update their Windows 10 computer, and if they don’t cooperate, the computer will stop working. Specifically, it will start rebooting itself every three hours, and if that doesn’t force your cooperation, eventually the computer will stop booting altogether.

Update 2016Sep22: The announcement for Windows 10 Insider Preview Build 14931 confirms that this is Microsoft’s new policy. No explanation is provided, although if pressed, I’m sure Microsoft would bloviate about ‘user experience’, ‘reliability’ and other things that sound good but deflect attention away from what’s actually going on, which is that Microsoft really wants to control what happens on your computer.

Recent updates to Windows 10 are causing headaches for Kindle and Powershell users.

Kindle users are reporting that simply plugging their Kindle into their Windows 10 PC is causing Windows 10 to crash. Two important Powershell features were rendered inoperable by the updates, making the jobs of system administrators more difficult.

Both problems are apparently the result of poorly-packaged cumulative updates. Microsoft is working on fixes, but seems to be in no hurry, since the fixes will not be available until August 30.

As with the webcam problems reported last week, these problems highlight what appear to be major holes in Microsoft’s new testing process, which relies on user feedback. Clearly, huge swaths of functionality are not being tested either by Microsoft or Insider users.

Microsoft wants us to let them update our Windows computers whenever they choose. Anyone using the Windows 10 Home edition is already living with this new reality, and — short of upgrading to Windows 10 Professional — can do nothing about it.

Of course, Windows 10 Professional is only slightly less invasive, as it only lets users delay updates for a few weeks. The only way to regain complete control over updates is to use one of the extremely pricey Enterprise or Education editions.

If you wanted to demonstrate just how awful this all is, you couldn’t ask for a better example than the recent anniversary update, which caused huge numbers of webcams to stop working.

Nothing in the release notes for the anniversary update provided any clues that this might happen. I imagine plenty of people simply assumed that their webcams had failed. Some may even have purchased new webcams.

Microsoft is apparently working on a fix, but there’s no indication of when it will be available. In the meantime, there are a lot of angry webcam users out there.

But wait a second: why wasn’t this problem reported by people with affected webcams who are on the Windows 10 Insider Preview program? The problematic changes were available to those users well in advance of the anniversary update’s release. If it was reported, Microsoft apparently failed to grasp the scope of the problem. A more likely explanation is that Insider Preview participants either don’t have webcam hardware (e.g. they test Windows 10 on a virtual machine), or simply never thought to test their webcam. Either way, Microsoft failed to perform adequate internal testing, and this doesn’t bode well for Microsoft’s reliance on the new Feedback mechanism.
