Hi Gran. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.
Try 1) Safe Mode with Networking, or 2) Safe Mode: https://www.digitalcitizen.life/4-ways-boot-saf...
Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...
Start with the infection scans in Step 7 and then check for broken system files in Step 11.
Then go back to the top to go over it most thoroughly.
Another thing you can do do if you haven't yet is manually install Fall Creator Version 1709 by installing Media Creation Tool and choosing to Upgrade Now. http://windows.microsoft.com/en-us/windows-10/m....
This the most stable method to upgrade to the new version (which you need anyway) and will bring you fully up to date with reinstalled Windows that often will solve any other problems you have.
You can use the same tool to download the ISO or create bootable media so you only need to do it once, and have the bootable media for repairs or possible Clean Install.
If there are any hurdles during the Upgrade see these steps to optimize the install as this is evidence it's corrupted: http://answers.microsoft.com/en-us/windows/wiki...
But remember that a factory or Upgrade install are inferior installs that most enthusiasts would never run in the first place because they'd expect endless issues. Most prefer to do the gold standard Clean install from this link which has had no reported issues: http://answers.microsoft.com/en-us/windows/wiki...
There is also an automated Refresh that reinstalls WIndows while shedding corrupting factory bloatware, saves your files, but doesn't clear the drive to get it cleanest: https://www.howtogeek.com/265054/how-to-easily-...
I hope this helps. Feel free to ask back any questions and let us know how it goes. I'll keep working with you until this is resolved.
