As Jack mentioned your comp is in a notification state after years of being installed, this points towards a program/infection that has been installed on your system in the last 5 months.
(you have re-armed either 2 or 4 times, more likely the the latter as you have a system builder licence)
I do have a fix BUT if its an infection it will be overwritten on a reboot.
Please run the following
ESET on-line scan (dissable any other AV)
Malwarebytes
remove anything found
reboot
Create a restore point
reboot
If its a program then the fix will not work until its removed, as i said its likely that it was installed in the last 5 months, if you can remember which uninstall it/them.
The fix
Please open an Elevated Command Prompt, and run the following commands
TAKEOWN /F C:\Windows\System32\slui.exe /A
ICACLS C:\Windows\System32\slui.exe /remove:d Everyone
ICACLS C:\Windows\System32\slui.exe /grant "NT SERVICE\TrustedInstaller":F)
ICACLS C:\Windows\System32
rerun/post the Mgadiag
