How to fix Task Manager taking up too much CPU

Question

Ever since I had upgraded to Windows 10, I had issues with my applications randomly crashing, and I realized soon after that every time this happens, my CPU would reach abnormally high levels, according to my task manager. Recently, I learned about PowerShell, and used the command "Get-Process". I had finally found the main culprit...

Admittedly, other processes would create high CPU usage aswell, such as WMIPrvSE, TiWorker and Windows Defender, but I had solved all of those other issues already, and Task Manager still remains the big culprit. How can I fix this???

*P.S: Task Manager would also show high usage, but all other processes wouldn't add up to the amount of CPU usage Task Manager shows me.

Hello, Suggest you to run System File Checker scan: Search for 'command prompt' using Cortana or Windows Search. From results, right click on Command Prompt and select Run as administrator. Type sfc /scannow command and press Enter key. Let the command complete and then reboot the machine.If that doesn't works, try these steps: Search for 'windows powershell' using Cortana or Windows Search. From results, choose Windows PowerShell and select Run as administrator. Then type/paste following and press Enter key: Repair-WindowsImage -Online -RestoreHealth

Let the command complete, restart your system then.

Hello  Did the issue crash issue occur with specific application or all the applications?

1. Since the issue occurred after we upgraded to Windows 10, have we checked the device manufacturer website whether present device is compatible with Windows 10.
2. If you have installed any third party antivirus software, we could try to uninstalled third party antivirus software then reboot to check. We may perform a clean boot to check the issue. How to perform a clean boot in Windows - Microsoft Support
3. The taskmgr process is task manager, we could just close the task manager process and not open it if the issue is related to this process. Anyway, I think this may be wrong direction.
4. Usually for application crash issue, there should be 1001 error event recorded in Event Viewer\Windows Logs\Application. We could check this record for any useful information. Foradvacned troubleshooting, the dump is usually. We could run the following command line (run as administrator) to confiure the app crash dump. Reg Add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps" /f Reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps" /V DumpFolder /t REG_SZ /D "C:\CrashDumps" /f MD C:\CrashDumps Reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps" /V DumpType /t REG_DWORD /D 2 /f Reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps" /V DumpCount /t REG_DWORD /D 10 /f Reboot then check whether there is any related dump saved to C:\CrashDumps folder. We could try to open the dump with debugdiag tool.

5. If the issue only occurred with the specific applicaiton, we may ask for help from the application support. Best Regards, Wesley Li ============================================ If the Answer is helpful, please click "Accept Answer" and upvote it.
