I had this same issue.
C:/ProgramData/Windows 10/Windows 10.exe was running and restarted itself every time I killed it from Task Manager. Scanning with Windows Defender did not indicate it was a malicious program. If I let it run while my network was up, CPU usage would go straight to 100% and stay there. Disabling my network interface made the CPU usage drop to normal idle levels. Trying to send the program to the Recycle Bin gave an error because it was in use. I ended up using Windows 10 Bash to mv the executable to a different name. This prevented it from restarting when it was killed from Task Manager.
Additionally, there were two other programs I was unfamiliar with that showed up in Task Manager. One was called Init, with no extension listed. Nothing happened when using "Open file location" in Task Manager on it. I killed that as well and it went away. (EDIT: this was part of Ubuntu and unrelated) There was another program called C:/ProgramData/lnpptcc/lnpptcc.exe. This I also killed and deleted.
These processes have not come back after I did the above. I saved copies of the two executables I could find for later analysis, but I have a bad feeling those processes were doing more than pinging Google.com.
I'm running a full system scan with Windows Defender at the moment to see if anything else comes up. Will update this post if I find anything else relevant.
