There is no one-size-fits-all answer to this question, as the answer will vary depending on the version of Windows and WMI that you are using. However, some methods for checking whether WMI is enabled on a Windows machine include:
Open a command prompt and type “net use wmic” to access the WMI management console. If you are not prompted for a password, then WMI is likely not enabled on your computer.

WMIC commands are used to manage Windows servers and workstations. They can be used to perform tasks such as adding or removing hardware, managing services, and viewing system information.

There are a few ways to fix WMI errors. One way is to restart the computer. Another way is to clear the WMI cache.

There are a few ways to enable WMI in Windows 11. The easiest way is to open the Control Panel, click on System and Security, click on Administrative Tools, and then click on WMI. Alternatively, you can open the command prompt and type wmic /namespace:\root\CIMV2 /enable.

Windows Management Instrumentation (WMI) is a platform that enables administrators to manage Windows-based computers and applications. It provides a comprehensive, centralized management interface for managing system resources, including hardware, software, and configuration settings. WMI also enables administrators to collect performance data and manage diagnostics.

To open Windows Management Instrumentation, run the following command from an elevated command prompt:
wmi.exe /online /enable
This will open the Windows Management Instrumentation console.
