However, it's highly not recommended to do so. According to the service's details, stopping Windows Management Instrumentation will cause most Windows-based software to not function properly. We recommend never disabling or stopping this service, nor the corresponding process in the Task Manager.Open the Command Prompt as an administrator. Type "net stop winmgmt" and press Enter. If prompted, type "Y" to stop the WMI service.Windows Management Instrumentation (WMI) is a set of specifications from Microsoft for consolidating the management of devices and applications in a network from Windows computing systems. WMI provides users with information about the status of local or remote computer systems.

Why is WMI using so much CPU : WMI Provider Host shouldn't normally use much CPU, as it shouldn't normally be doing anything. It may occasionally use some CPU when another piece of software or script on your PC asks for information via WMI, and that's normal. High CPU usage is likely just a sign that another application is requesting data via WMI.

Is WMI needed

Importance of WMI in Windows Systems

Examples include monitoring CPU and memory usage, checking disk space, retrieving information about installed software and hardware devices, and configuring network settings. WMI can also be used by third-party software vendors to develop management applications for Windows systems.

What is WMI malware : Windows Management Instrumentation – T1047

The WMI service communicates by using Remote Procedure Calls (RPCs) over port 135. This service is often abused by attackers to move laterally in the network and deploy malicious commands by using the WMI cmdlet (WMIC) or executing files remotely.

Although system administrators can use WMI in all Windows-based applications, it's most useful in enterprise applications and administrative scripts. For more information about WMI, see Further information for WMI.

For example, when such a tool shows that the computer's CPU is at 100% usage, it tells you your CPU is working at its maximum capacity.

WMI can be a powerful tool for managing Windows systems, but it also raises privacy concerns. Because WMI provides detailed information about system configuration, performance and usage, it can potentially be used to collect sensitive information about users and applications without their knowledge or consent.

How do I know if my WMI is disabled : Confirm WMI is broken

  1. Launch the WMI MMC snapin: go to Start -> Run -> type wmimgmt.msc.
