Before it was working,
Now I am assuming that th blank parts are - where your "ordinatuer" is should be filled with others?
The reason I asked how long this had been the case is because you could use system restore to before the date this started to happen.
However there are a few things that can do this - malware obviously, the file system getting corrupted and a recent update would be three things I would target first because they are known culprits.
Plus for example the problem started three days ago then just restore back to before that date but before
you do that run sfc and then these on call scanners all are free and just maybe pick up a PITA piece of malware that sometimes load just to make life difficult.
So start with a sfc /scannow SFC /SCANNOW Command - System File Checker

If these come up with anything get rid of it if not then do the system restore this is just some simple things to do first to eliminate things as we go.
Do these in that order and let us know what happens.
