RepCad Posted May 9, 2020 Share Posted May 9, 2020 Hi every one, I'm using this code to get unique serial of any system : (setq nu (vlax-get-property (vlax-invoke (vlax-create-object "Scripting.FileSystemObject") 'Getdrive "c:" ) "SerialNumber" ) ) It works well for each system, but only problem that I have with the code is that the serial number changes when widows changes. or it gives two different serial numbers when computer has two windows (two operations). is there a permanent serial (unchangeable) on system and unique for each system?

No it doesn't - the MAC address is a physical address hard coded into the hardware and is therefore independent of the OS. 1 Quote Link to comment Share on other sites More sharing options...
