We are aware of an issue whereby a recent Windows Update - KB5063060 - is causing conflicts with ThreatLocker and other security software leading to slowness and instability on some Windows 24H2 systems.

We are currently testing a fix which will be included in the ThreatLocker 10.3 which we hope to have available as a public beta tomorrow.

A temporary solution is to downgrade affected machines to ThreatLocker version 10.0.9.
