RE: Unique identifier for machine

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Hi Alex,

I got another idea, maybe you could use the 96-bit unique ID, which is the
middle part subauthority of the target Windows system's Administrator or
Guest account SID, it is generated during the Windows system installation
time.

Administrator: S-1-5-21-XXXX-XXXX-XXXX-500
Guest: S-1-5-21-XXXX-XXXX-XXXX-501

You can use the API LookupAccountName to retrive it.


Thanks!

Best regards,
