Windows 10 Anniversary Update is reported to cause millions of webcams to stop working

Microsoft decided to exclude both H.264 and MJPEG codec support for millions of webcams. This includes cameras from manufacturers like Logitech.  According to Microsoft-focused blog Thurrott.com, this was supposedly a decision the company made to prevent performance issues now that certain Windows apps have more direct webcam access post-update.

Members of Microsoft’s Windows Camera team are performing damage control in support threads, and Thurrott.com reports an official fix may be in the works for a September release. Unfortunately, that may only remedy the MJPEG format. Those who rely on H.264 may be waiting even longer to make use of their webcams. If you recently installed the Windows 10 Anniversary Update, you can revert to the prior version of the software within 10 days.
