2] Run SFC and DISM

The problem can be because of a corrupted file system and to fix it we need to run two commands. Since PowerShell is giving you a hard time, we are going to use Command Prompt. So, launch Command Prompt as an administrator and run the following commands to run SFC and DISM.

sfc/ scannow
dism /online /cleanup-image /restorehealth

Like any other high CPU usage problem, the one caused by PowerShell can be because of viruses and Malware. You can use any third-party application to scan your computer but we are going to use Windows Defender. So, if you want to use Windows Defender to scan your computer for viruses and malware, try the following procedure.

  1. Launch Settings by Win + I.
  2. Click Update & Security > Windows Security > Open Windows Security.
  3. Click Virus & threat protection > Scan Options > Microsoft Defender Offline Scan > Scan now.

Now, wait for the process to complete and remove all traces of virus and malware from your computer and see if the issue is fixed.

4] Reinstall PowerShell

If you are using PowerShell 7, you can uninstall it and then reinstall it.

5] Use Cloud Reset

Use the Cloud Reset option and see if that helps.

6] Repair Windows 10 using Installation Media

Last but not least, if nothing works, try repairing Windows 10 using Installation Media. This won’t delete any of your personal files and will fix the issue for you.

Hopefully, you are able to fix the PowerShell issue with the help of these solutions.
