Port 9001 has become occupied by the windows system service. How to kill a process?

Question

System administration

Good day to all.
The problem is this: on windows I use OpenServer for quick editing and testing of databases, sites, scripts.
Just the day before yesterday, the OS stopped starting with the error
"Unable to occupy port 9001 because it is already in use: Windows services"
using netstat found out the PID of the service occupying the port. (id 4 --- SYSTEM). the executable file ntoskrnl.exe
deleted the software downloaded the last day, ran the system just in case with antivirus programs. nothing ... of course, I can’t disable the service. I'm not right enough, and I don't know what it will lead to.

why OpenServer did not understand this port either, checked the ports used in the configs, 9001 is free. php was at 9000, changed to another free one.
in the windows components disabled the ISS service just in case, all to no purpose. what could be the problem? Too lazy to roll back the system because of the closed port, and open server on Windows is a very convenient thing.
and just wondering what the problem is, maybe someone came across

also faced the problem of busy port 9001
intel occupied this port for the graphics card
here is the solution to the problem:
1. Star menu
2. write: Services
3. Find the service: Intel(R) Graphics Command Center Service
4. right-click -> Properties - > Startup type = Disabled
