Windows 10: Event 10016 continues even after typical fix - DCOM error in WIM every 4 hours even after...

Since upgrading two months ago from version 1709 to 1803, I get these error messages once every four hours even after fixing the error the usual way:



The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{8BC3F05E-D86B-11D0-A075-00C04FB68820}
and APPID
{8BC3F05E-D86B-11D0-A075-00C04FB68820}
to the user DESKTOP-3*****N\[My Name] SID (S-1-5-21-3591163430-416291016-3566129944-1001) from address LocalHost (Using LRPC) running in the application container Microsoft.Windows.ContentDeliveryManager_10.0.17134.1_neutral_neutral_cw5n1h2txyewy SID (S-1-15-2-350187224-1905355452-1037786396-3028148496-2624191407-3283318427-1255436723). This security permission can be modified using the Component Services administrative tool.



The AppID is for Windows Management and Instrumentation.


Using the old techniques, I added all of: myself, SYSTEM and LOCAL SERVICE to the DCOM - Security - Launch and Activation with all three of them checked for Local Launch and Local Activation, but the Error messages keep coming.


Why? Is it because this is coming from "the application container Microsoft.Windows.ContentDeliveryManager_10.0.17134.1_neutral_neutral_cw5n1h2txyewy SID (S-1-15-2-350187224-1905355452-1037786396-3028148496-2624191407-3283318427-1255436723)", which I've never seen before?


So - what do we do now?

DCOM error 10016


Well, I am bumfuzzled! I went in to my Event Viewer to take a look before applying the process referenced by Qwinn to fix the 10016 Dcom errors. There were no new ones, so I rebooted several times and still no 10016 Dcom errors! I don't know why, but I'm glad they are gone. Thanks to Qwinn and I will save your reference for future use, if needed.

Cortana and DCOM Error Event 10016


My PC was giving many DCOM error 10016 involving Cortana as follows:

The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID {C2F03A33-21F5-47FA-B4BB-156362A2F239} and APPID {316CDED5-E4AE-4B15-9113-7055D84DCC97} to the user PC-PC\PC from address LocalHost (Using LRPC) running in the application container Microsoft.Windows.Cortana_1.6.1.52_neutral_neutral_cw5n1h2txyewy.This security permission can be modified using the Component Services administrative tool.

I fixed this by giving Administrator permissions to the two registry keys mentioned above, by editing the registry as per these instructions:
Windows 10 Event 10016 Fix: The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {D63B10C5-BB46-4990-A94F-E40B9D520160} and APPID {9CA88EE3-ACB7-47C8-AFC4-AB702511C276} to the user NT AUTHORITY\LOCAL SERVICE SID (S-1-5-19) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.I a – Quarter Five – Thoughts and Solutions

The next step is to change the DCOM settings in DCOM Config. I had to change the DCOM settings by going to Component Services, then opening Computers, then right clicking on My Computer then selecting Properties. Then under Access Permissions click "Edit Limits" and adding Administrators to the group.

After a PC reboot the errors no longer come up.

My question is, is adding Administrators to the group under Access Permissions a good way to do it, or is there a better way? Have I inadvertantly done something bad that will upset something else (so far so good).
