'wmic' Command

Last reviewed: June 2, 2026

Failed to get processes tree usage data.

This is probably because the 'wmic' command is not available in your system.

If you are on Windows 11 or Windows Server 2025, you can enable it in the Wndows Features settings.

That error is happening because the wmic (Windows Management Instrumentation Command-line) tool is missing or disabled on your system.


Newer versions of Windows (like Windows 11 and Server 2025) have deprecated WMIC by default, but you can re-enable it or use a modern alternative.

Here’s how to fix it depending on your setup:

Option 1: Re-enable WMIC on Windows 11 / Server 2025​

  1. Press Windows + R, type:

    optionalfeatures

    and press Enter.

  2. In the Windows Features window:

    • Scroll down to Legacy Components or WMIC (if shown).
    • Check the box next to it and click OK.

  3. Reboot your system.

  4. Test in Command Prompt:

    wmic

    If it opens the WMIC prompt, it’s restored.

Option 2: Use PowerShell Equivalent​

If WMIC isn’t available or can’t be re-enabled, you can replace its functionality with PowerShell.

For example, if your application/script is trying to get CPU or process info via WMIC, you can use:

Get-Process
Get-WmiObject Win32_Process

If it’s your own code, replace WMIC calls with PowerShell equivalents.

Option 3: Manually Reinstall WMIC​

If “Windows Features” doesn’t list WMIC:

  1. Open PowerShell (Admin).

  2. Run:

    dism /online /add-capability /capabilityname:WMIC~~~~

  3. Restart your machine.
