Is I've yet to see that message tie back to a PC crash or shutdown. I've always found it to be something else other than what you've detailed above.
Since there are no PC details I fear you have to reset Windows 10 if you believe it's this or take it to a repair counter or if new, use your warranty. I'd want to avoid all this but I only have what you shared so far.
In your last long paragraph it appears you may have corrupted Windows which is where at the shop we help the owner get at their files so a reset is done or most want to move to SSD so a new SSD is installed, Windows 10 is reinstalled and the old HDD is added as a second drive so they can use that to get to their files and later as bulk storage.
So first off I am not very inclined with computers.
I am running windows 10 on a higher end desktop purchased 1 year ago. I am experiencing sudden pc shutdown every other day. In the event viewer at time of crash I am getting this system error:
The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
to the user DESKTOP-HJANLRO\Dura SID (S-1-5-21-4056686221-993884268-2685281155-1001) 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 have followed several guides relating to this problem. Including this one:
Following the guide, I was not able to follow the step "Find the RunTimeBroker >> Right Click >> Properties >> Security Tab". There are two entries for RunTimeBroker, I was able to change permissions on one entry but the other I was not given permission and it is the one causing the issue. I messed up and someone lost all permissions for windows, no file explorer, cmd not functioning - luckily I was able to roll back. This issue is straight up annoying and I need help and a step by step on how to fix this. There is only one user with admin rights. I appreciate any help on this.
