Detailed Operation Procedure

1. Backing up the original device identifier
   • Windows scripts modify the system registry'sHKLM\SOFTWARE\Microsoft\Cryptography\MachineGuidand automatically backs up to%USERPROFILE%\MachineGuid_BackupsCatalog.
   • The macOS script creates a fakeioregcommand to emulate the different device identifiers, and the originalIOPlatformUUIDBackup to~/IOPlatformUUID_BackupsCatalog.
2. Reset device identification
   • Windows systems: the script generates a newMachineGuid,telemetry.machineId,telemetry.macMachineId,telemetry.devDeviceIdcap (a poem)telemetry.sqmIdand update the registry andstorage.jsonDocumentation.
   • macOS systems: the script generates new device identifiers, which can be changed by modifying thePATHenvironment variables to simulate different device identifiers.
3. Restore original device identification
   • If you need to restore the original device identifier, you can find the corresponding backup file from the backup directory and then restore the value through the registry editor or terminal.
