Default is RollbackDisabled.

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
Rollback to target version


  1. Do not roll back to target version if OS version is newer than target. Updates are also disabled.
    Registry HiveHKEY_LOCAL_MACHINE
    Registry PathSoftware\Policies\Google\ChromeOS
    Value NameDeviceRollbackToTargetVersion
    Value TypeREG_DWORD
    Value1
  2. Roll back and stay on target version if OS version is newer than target. Do a powerwash during the process.
    Registry HiveHKEY_LOCAL_MACHINE
    Registry PathSoftware\Policies\Google\ChromeOS
    Value NameDeviceRollbackToTargetVersion
    Value TypeREG_DWORD
    Value2
  3. Roll back and stay on target version if OS version is newer than target. Try to carry over device-level configuration (including network credentials) through the rollback process, if possible, but do the rollback with full powerwash even if restoring the data is not possible (because the target version doesn't support restoring data or because of a backward-incompatible change). Supported on Google Chrome OS version 75 and higher. For older clients, this value means that rollback is disabled.
    Registry HiveHKEY_LOCAL_MACHINE
    Registry PathSoftware\Policies\Google\ChromeOS
    Value NameDeviceRollbackToTargetVersion
    Value TypeREG_DWORD
    Value3
