Why doesn't windows kill the process as administrator?

Question

Windows

For me, it’s generally a big surprise that in windows the administrator is not an administrator. How can an administrator be denied access at all? He's also an administrator. Unfenced access rights to anything and everything, no?

Answer 1

See what process. There are processes that cannot be disabled in principle.

Answer 2

If the process belongs to the kernel, then its termination may result in a system crash.
You can open the location of the file from the task manager, see its properties if it is not a system file.
What exactly is this process? If it is a service, then it can be stopped.
Try to kill the process through the taskkill console with a command with different parameters
