re: post under After a recent feature update I am facing problems with the integrated cameras on my laptop


My external webacm and mic stopped working after the Win 10 version 2004 upgrade on 8/19/20.


I have tried the following w/o success:

1. ensured camera was set to allow apps to view it
2. plugging the webcam in diff usb port
3. uninstalling/reinstalling the device, checking for new hardware, updating the driver
4. rolling back the windows 10 version 2004 update, (made removable usb recovery drive first)
5. tried regsitry update suggested (made backup of it before hand) of creating 32 bit DWORD value named EnableFrameServerMode under the following folder HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Foundation\Platform .......I am going to undo this and not save the changes because the reference I found (from you tube (yes I acknowledge that is a 'use at your own risk" sceanario) said if you have 64 bit machine; which I do) to also add same entry under folder HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform but that folder does not exist and there is only Internet Explorer subfolder under HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft

I am totally at a loss at this point. Any other suggestions?
