Windows audio endpoint / Windows Audio not responding

Hello CasWijers 

No worries, I would like you to complete a few steps for me. 

1- Run CMD as an admin and enter the commands below: (these will remove the windows update registry which means next time you check for updates, WU will check against the entire windows update database)

Reg delete HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate

yes

Net stop wuauserv >NUL

Cd C:\windows

rmdir softwaredistribution /s /q

Net start wuauserv >NUL

2 - Then run the following in order, one after the other. Wait for the first one to complete, then enter the next one: (these will repair windows and look for corrupted files)

DISM.exe /Online /Cleanup-image /Restorehealth

fsutil resource setautoreset true C:\

sfc /scannow

3- Now run Windows update > new updates should pop up. 

4- Assuming your chipset is intel, go to the site below and install the driver assistant, run the tool on your machine.

Intel® Driver & Support Assistant

5- After this the problem should be resolved. 

Regarding buying 3rd party programs to fix these issues, most of them don't work. I would not use them. I rather find the driver required from the manufacturer site. This is always the best and safest way to update or fix hardware. 

Hope this helps.

Thanks,

Jose
