What Is WMI Provider Host? 

Fix WMI Provider Host

WMI (Windows Management Instrumentation) is a set of system management tools that Microsoft has built into every version of Windows since Windows NT 3.1.

It allows applications to access information about the operating system without needing direct user interaction.

This includes things like hardware inventory, software installation status, network configuration, printer settings, and more.

The WMI service runs in the background and provides this information for all users. 

The WMI service uses a special type of process called a “provider” to provide these services. Providers are processes that run in the background and provide information to other programs.

They do not require any user input or interaction. There are two types of providers: local and remote. Local providers run only within the same computer as the application requesting them.

Remote providers allow an app to request data from another computer over the network. 

The WMI service automatically starts when you install Windows. However, there are some cases where the WMI service can cause problems.

If you have a slow Internet connection, or if your computer is connected to a VPN, then the WMI service will use up a lot of resources. In these situations, you might notice that your PC becomes unresponsive or slows down.
