Note: It is recommended to update a small group of machines to 7.6 prior to global deployment due to the significant amount of changes made to this build. Here is how you can update individual machines or specific groups: Updating the ThreatLocker Version on a Single Computer | ThreatLocker Help Center (kb.help) | Updating ThreatLocker to the Latest Version | ThreatLocker Help Center (kb.help)
