Temporarily Disable ThreatLocker

In the event that you are removing ThreatLocker in order to verify that ThreatLocker itself is not responsible for an application not functioning, you are able to stop the ThreatLocker Service temporarily. 

ThreatLocker cannot be uninstalled or stopped while Tamper Protection is enabled. 

To temporarily stop the ThreatLocker service:

  • Disable Tamper Protection (For instructions on how to disable tamper protection, please refer to our article) -- Disabling Tamper Protection
  • Open Command Prompt as an Administrator.
  • Type "net stop HealthTLService" to stop the Health Service. (This step must be done before you attempt to stop the ThreatLocker Service as it will revive the ThreatLocker Service)
Note: On older versions of ThreatLocker, the Health Service is named "HealthTService" 
  • Type "net stop threatlockerservice" to stop the ThreatLocker Service.
  • Press Enter. 

You may also manually stop the services in the Windows Services control panel.
