Windows 10 Anniversary update was supposed to polish the performance and features of Windows 10. There are some reported issues with hardware problems, internet issues, features such as Start Menu etc. One more widely reported problem is the one which broke down the webcam in plenty of systems.
In reality, it did not destroy your webcam. The problem is simply because Microsoft decided not to support streaming videos in MPEG and H.264 format. So the problem can simply be resolved if Microsoft add support for the unsupported video format. Microsoft is already aware of the situation and hopefully will be fixed by releasing an update soon.
There is a work around which seems to be working. This one is credited to Rafael Rivera, a columnist for Paul Thurrott.
Please Note: This require you to make changes in Registry. Making the wrong changes in Registry can even lead to a system crash. So it is highly recommended to take a backup before making changes.
If you are not comfortable editing registry, it is worth waiting for a while till Microsoft release update.
- Windows Key + R for opening Run window
- Type regedit and click OK to open registry editor
- Go to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows Media Foundation \ Platform
- Right click on Platform -> Select New -> DWORD
- Name the DWORD as EnableFrameServerMode.Click OK.
- Right click on the new DWORD -> Click Modify -> Enter 0 as value in Value data field.
- Go to HKEY_LOCAL_MACHINE \ SOFTWARE \ WOW6432Node \ Microsoft \ Windows Media Foundation \ Platform
- Repeat the same step as above from 4 to 7.
Restart computer and check if the webcam started working.
If this step didn’t work, it is better to wait for some time till Microsoft release a new update which will fix the problem.
