Microsoft's Windows 10 Anniversary Update has blocked certain webcams from functioning and frozen Skype calls for some users.
According to tech blog Thurrot, the issue affects USB webcams that use MJPEG or H263 encoded streams, and will only allow YUY2 encoding,
The Anniversary Update gives multiple applications access to the camera in new ways that weren't available before facial recognition tool Windows Hello and augmented reality headset Microsoft Hololens.
Windows Camera Team engineer Mike M told users on a Microsoft forum from that support for the codec was removed to stop PC performance degrading due to multiple applications decoding the same stream.
He added that a fix was expected to arrive as an update in September.
The anniversary date started rolling out on 2 August, a little over a year after Windows 10 was released. The update includes a handful of new features such as third-party integration of Windows Hello and updates to Microsoft's new browser Edge.
Windows 10 has surpassed over 350 million downloads in the first year of release.
