Added the ability to prevent the ThreatLocker service from being stopped.

You can configure a registry key to prevent an administrator from stopping the ThreatLocker service. When adding the PreventStop DWORD into the HKLM\Software\ThreatLocker with a value of 1. An administrator will not be able to stop the ThreatLocker service. If you rename the MSI from to nostoptl_xxxxxx.msi, the registry will automatically be added on deployment.

Added the Ability to Configure Excluded Processes for a Computer Group.

You may want to exclude certain applications from ThreatLocker Storage Control. For example, if you have an antivirus program that is scanning multiple files, you can exclude it from being blocked or processed by ThreatLocker. To add an exclusion to ThreatLocker:-

  1. Select Computer Groups from the navigation menu;

  2. Select the edit icon next to a group.

  3. Scroll down to the excluded processes section. You can add process names, such as c:\program files\myavprogram\app.exe

Added the ability to configure a Splunk instance in the policy page.

Previously Splunk integration must be configured by ThreatLocker Service team. We have now added the ability to configure Splunk right from the edit Policy page.


  • Changed default configuration of ThreatLocker Service to restart on termination.

  • Changed the Application Policies page to display a loading indicator when refreshing policies.

The following fixes have been applied.

  • Fixed issue where the service would terminate if a write of the baseline is denied to the disk by an antivirus product.

  • Fixed issue where some updates on Windows Server 2008 (Release 1 only), causes a BSOD.

  • Fixed issue where a folder with no name could cause the ThreatLockerService to crash when scanning the baseline.

  • Fixed issue where some files are missed when scanning the baseline.
