The biggest problem is that you will not be able to access updates other than the Security ones - but such updates provide system improvements, and so you may find that your system responds slowly (or at least more slowly than it would do otherwise).
You will also be barred from access to certain areas of the system - and such areas allow control that is not otherwise available.
At the moment, all I can advise is that you attempt an SFC scan - it may correct some problems, and may also allow us to see what has happened....
SFC -System File Checker - Instructions
Click on the Start button
type in the Search box
CMD.EXE
right-click on the only file that is found
Select Run as Administrator
- the Elevated Command Prompt window should pop up
At the Command prompt, type
SFC /SCANNOW
and hit the Enter key
Wait for the scan to finish - make a note of any error messages - and then reboot.
run another MGADiag report, and post the results.
I've done scan and here is what it said:
Windows Resource Protectio found corrupt files and successfully repaired them.
Details include in the CBS.log windir\Logs\CBS\CBS.log
The new MGADiag report is here after i reboot:
