Windows 10: All my apps have very high cpu percentage after restarting.

I restarted and updated my pc last night and this morning returned to it being extremely laggy once booted. It took several minutes to load a single app, so I rolled back the windows update. This helped a bit but it is still extremely slow.I was to emphasis that it isn't a single app doing this, but rather the already existing apps, which were completely fine yesterday, are using a lot more of my cpu.

Shutdown restarts and high CPU

I have two issues please that I would like some advice:

Conditions for error:

When I leave my computer on idle for more than 2 hours plus, the computer

1. Goes into 197% CPU usage
2. When I shutdown, goes into restart and not shut down

What have I done to resolve this?

1. This happens on two accounts
2. Updated firmware to latest bios
3. Run diagnostics; task manager, CPUID, perfmon, all with no issues reported
4. Sent the device back to the supplier for them to run diagnostics
5. Disabled high CPU applications (the biggest being qsynch)
6. Reviewed online rports and changed restrty settings on HK Local
7. Reviwed power management as suggested
8. Run Malwarebytes, Bitdefender, and EDR Comodo
9. Run qualys vulnerability scan
10. Checked windows defender

My setup:

1. Intel NUC I7 10th generation bought from simply NUC
2. 64 gb of RAM
3. 1tb Samsung 970 NVME
4. Windows 10 pro, with all latest updates
5. High speed broadband

I would be grateful for some advice re what to do next to fix this issue.

Regards,

Mike

 

Windows Explorer high CPU Usage in Windows 10

Hi Andrew,

Usually, too many background processes can boost your CPU usage. Since you already disabled the apps that are not necessary on startup,
we suggest checking the applications running once you have successfully boot Windows 10. To do this, simply follow the steps below:

• Click on the Start button and type Task Manager on the search box.
• On the Task Manager window, you should see the programs running.
• Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

From there, you should see what applications are running on high CPU usage. You can also
restart the Windows Management Instrumentation service and see if your CPU performance will improve. Follow the instructions below to restart the service:

• Click on the Start button and type Services.
• Scroll down the list and look for Windows Management Instrumentation.
• Right click on it and select Restart.

Should you have further questions, please let us know.
