We recommend never disabling or stopping this service, nor the corresponding process in the Task Manager.WMI Service process communicates with providers, consumer clients and the services.exe via Advanced Local Procedure Calls (ALPC) communication channels. In the WMI Threat model presented by Binarly, attacking the ALPC communication channels is one of the ways to disable WMI without triggering any security alert.Stop the service "Windows Management Instrumentation". Type "net stop winmgmt" and confirm with "Y". Open Windows Explorer and navigate to the path C:\windows\system32\wbem and rename the folder "Repository" to e.g. "Repository_old".

What does WMI do

Windows Management Instrumentation (WMI) is a subsystem of PowerShell that gives admins access to powerful system monitoring tools. Though this system has been designed to allow for fast, efficient system administration, it also has a spookier side: it can be abused by insiders as a tool to surveil other employees.There's no simple strategy for limiting the effectiveness of adversarial abuse of WMI. As is often the case with techniques that are common Windows utilities or processes, the nuclear option of disabling the Winmgmt service is not recommended because legitimate code often relies upon WMI.Disadvantages :

  • Speed – It is slow to query data and if you are trying to use it during start up it can delay you starting as the WMI service takes a long time to come up.
  • WMI is less efficient as compared to SNMP.
  • Significantly more firewall ports required in case of WMI.


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.
