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.
