WS2012 Standard R2 with Essentials sudden problem with Server Manager, Essential Dashboard and other services

Question

Hi all,
I have a problem with my Windows Server 2012 R2 with Essential installed. When I try to run Server Manager the server manager window doesn't appear and the same thing applies for starting the essentials dashboard. This leads to that some of the features doesn't
work properly like remote web access, client backup and so on. When I check the Services a lot of services haven't even started. Trying to manually start for example Windows Server Essentials Management Services gives me following error message: 
"Windows could not start the Windows Server Essentials Management Services on Local Computer. Error 1068: The dependency service or group failed to start"
What can be wrong here? I haven't done anything to the server that could start these problems. This started all of a sudden. 
Thank you all in advance for any help.
EDIT:
I rebooted my server in safe mode and I tried to run SFC /Scannow which stops at 84% and gives me following message:
"Windows Resource Protection could not perform the requested operation."
I also tried to run "DISM.exe /Online /Cleanup-Image /RestoreHealth". This did not help either. It completes the operation but nothing changes. The problem is still there.
I thought that my server backups were OK and that this problem would be gone by restoring the C: drive with backup image. The problem is that all my good backups was rewritten with new backups that could not take backup of the C: drive for some reason. Now
I need to solve this problem without reinstalling the whole operating system.
EDIT:
I have also completed the chkdsk C: /r command and now the SFC /Scannow command can be completed, with notification that some files could not be fixed. I have attached the sfcdetail.txt file which points out that
"tsgclean.exe" cannot be repaired. What has that file to do with my WS2012 problems...

Hi,
Did you remember any operation which you had done before this issue occurred? For examples, install any update,
install any third-party application or any other? Just a confirmation, thanks for your understanding.
For those problematic services, please open services’ Properties and navigate to
Dependencies tab, then check if all system components which this service depends on run as normal.
In addition, please open Event Viewer and check if find relevant events. Meanwhile, please follow the path:
%programdata%\Microsoft\Windows Server\Logs and check Dashboard log file if find more clues.
By the way, when you run
sfc /scannow command completely, did you open Server Manager or Dashboard again? Any difference?
If any update, please feel free to let me know.
Hope this helps.
Best regards,
Justin Gu

Hello Justin,
Regarding the third-party applications:
I have not installed any third-party application that could cause this problem. All my third-party applications that are installed on the WS2012 R2 are confirmed working well with the operative system and are installed at the time when I hadn't these problems.
I cannot say anything about windows update because that is something that I update once in a week after checking that no user is reporting any issues. I have learned my leason with windows update when I had Surface Pro 2, that was a dissaster.
Regarding the Windows Updates:
Anyway, I tried to remove all the windows updates before as well (not the security updates) down to 5th December which is the time when I know that my server worked well. Only two updates could not be removed (KB3012199 and KB2989647). I don't
know if these two updates can cause any problem?
Regarding the problematic services:
For example: Checking the properties for "Windows Server Essentials Management Service" -> It is dependable on
"1. Active Directory Domain Services" and "2. Windows Server Essentials Provider Registry Service".
No 1 is running but not no 2. If I try to start no 2 service it will give me the same message as before:
"Windows could not start the Windows Server Essentials Management Services on Local Computer. Error 1068: The dependency service or group failed to start"
Regarding the Logs:
I have uploaded Dashboard log files which are created after 5th December to my dropbox account: Link
Regarding the SFC command:
Of course, when the SFC command was completed but with error that it could not repair
tsgclean.exe I tried to start the essentials dashboard and WS2012 server manager with no luck.
What about the error message? I looked up that file in the explorer and it is located in folder "C:\Windows\WinSxS\amd64_microsoft-windows-tsproxy-edgeadapter_31bf3856ad364e35_6.3.9600.16384_none_2ec8d374a0ac5606"
Why can't it be repaired and what kind of file is that?
Best regards
