S-1-5-21-119163587-1573839180-90999006-1001

I give up, what is it - and what's a "security ownership panel?"

HKEY_USER\S-1-5-21-673314695-786634019-2142738235-1001\ Software\Microsoft\Internet

This is all that is installed on the above and it should have "explorer 11' at the end. Because that is missing, it is blocking some of my software. Since explorer 11 is a part of windows 10, it can not be uninstalled. Therefore, I can not uninstall and re-install.
WHAT CAN I DO TO CORRECT THIS PROBLEM??
