Hello

Thank you for posting in Microsoft Community forum.

It sounds like you're experiencing high CPU usage on your Windows 2016 server due to the NT KERNEL & SYSTEM process. This can be a common issue and there are several potential causes and solutions.

1. Check for Drivers Issues:
   • Outdated or faulty drivers can cause high CPU usage. Make sure all your drivers, especially for network, disk, and graphics, are up to date.
2. nvestigate with Performance Monitor:
   • Use Windows Performance Monitor to identify which processes or services are contributing to the high CPU usage.
   • Open Performance Monitor (type perfmon in the Run dialog: Windows Key + R) and create a custom data collector set to monitor CPU usage over time.
3. **Check for System Services and Processes:**
   • Use Task Manager and Resource Monitor to identify which processes are using significant CPU resources.
   • Open Task Manager (Ctrl + Shift + Esc), go to the "Processes" tab, and sort by "CPU" to see which processes are at the top.
4. **Analyze with Windows Debugging Tools:**
   • If you have more experience with debugging, you could use tools like WinDbg to analyze the kernel memory dumps for specific clues.
