in some cases, an automated script or system may enable this setting continuously, leading to false positives. to avoid such situations, it is recommended to monitor the frequency and context of the registry modification and modify or filter the detection rules as needed. this can help to reduce the number of false positives and ensure that only genuine threats are identified. additionally, it is important to investigate any detected instances of this modification and analyze them in the broader context of the system and network to determine if further action is necessary.
