Microsoft’s latest update to Windows 10 has accidentally disabled ‘millions’ of USB webcams and applications.

The Windows Anniversary update, released on 2nd August, changes which formats of video streams can be processed by Windows 10, which meant that a large number of devices were no longer able to communicate with the operating system.

The bug has affected many different brands of web camera and app, including Microsoft’s own Skype service.

With the update installed, Windows 10 stops software from accessing streams encoded in compressed MJPEG and H.264 formats, and instead forces them to use uncompressed YUV or NV12 streams. Any application that expects video streams in MJPEG or H.264 will not work.

Microsoft has said that a fix is being developed for the problem. Some third party manufacturers and developers were notified of the change and were able to update their products to accommodate it, but others

The Windows Anniversary update is the largest update so far to Windows 10, and was intended to provide new features and improvements to most parts of the operating system.
