You did a great job on discovering the events BEFORE the issue started to occur. I had this issue on my laptop since November, and it really bugged me. Like you, I sifted through the event log and found absolutely the same pattern you described.
In short, the pattern is as follows: Windows updates run automatically, and when reboot is initiated after the updates are finished, the computer crashes. When it boots up, it reports that the last shutdown was unexpected, and the issue begins to occur.
I spent 2 days trying to dig out a solution from the Internet, to no avail, until I came across
this page. It doesn't say anything about this particular problem, but it gives more information about SVCHOST process that starts many services, including Group Policy Client. It looks like during reboot a vital registry settings were lost and Group Policy
Client simply "doesn't know" how to start. Let me explain:
There are two places to look in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services this path should contain
gpsvc key (a folder), which is responsible for service parameters and configuration. I found that the key wasintact, so, you do not touch anything here.
This is the most important path you should look into, as it must contain the keys and values referred in the key #1. Below are descriptions what must be present there.
There must be Multi-String value called GPSvcGroup. My laptop was missing it. So, you should create multi-string value named
GPSvcGroup and assign it value GPSvc.
Next, you must create a key (a folder) and name it GPSvcGroup
Then open newly-created GPSvcGroup folder and create 2 DWORD values:
First called AuthenticationCapabilities and you must give it a value of 0x00003020 (or 12320 in decimal)
Second is called CoInitializeSecurityParam and it must have value of 1.
Once you completed all steps above, reboot the computer and the problem will be fixed.
I am so relieved I was able to fix it, and hope this will help others with the similar issue.
The resolution is quite easy. Ignore all those tech geeks here and on other sites who just want to show off how they can fiddle with registries--a very dangerous game. Go to Search, type cmd, open cmd as Administrator. Type exactly this (with indicated
spaces): netsh winsock repair then press Enter. You will need to Restart (NOT shut down and turn On) your computer. Bingo! Unfortunately this condition may re-occur from time to time, like if you Start your computer before turning on your internet and establishing
a good connection. No sweat the fix takes about 3-5 minutes depending upon your computer Restart speed.
