Update KB4550961 couldn´t be installed

Hi! I´ve tried hard to install KB 4550961 unsuccessfully. Even run this or that in order to correct whatever the problem might be.

However, after restart it appears “Updates couldn’t be installed” on the screen. Running Scannow and Restorehealth as Administrator didn´t
work either.

I´ve also gone step by step thru “Fix Windows Update errors” steps 1 to 5. I´m reluctant to follow Step 6 Reset or Reinstall Windows –
Refresh is not included - because I´m afraid I might loss some stuff important, though I created a restoration point and a USB recovery drive, just in case.
