Environment

• Carbon Black Cloud Sensor: All Supported Versions

Question

Answer

• Upgrades do not require a reboot, unless needed to initialize newly introduced drivers (see Additional Notes).
• Sensors left in a Bypass Error Status post-upgrade may require a reboot to remediate.
• Endpoints will never be forcefully rebooted after upgrading the Sensor, unless specified by a third-party utility (e.g. SCCM). 

Additional Notes

• The 3.7 Windows Sensor introduced an additional driver that monitors the storage volume for ransomware attacks against the MBR.
• Upgrades from pre-3.7 Sensor versions to 3.7 or higher will require a reboot to gain the benefit of this new ransomware functionality.
