_UniqueHardwaeIDv1()

Recommended Posts

Yashied

This function generate a unique hardware identifier (ID) for your computer given the specified parameters ($UHID_... flags).

$UHID_MB (0x00)

Uses information about your motherboard. This flag is used by default regardless of whether specified or not.

$UHID_BIOS (0x01)

Uses information from BIOS.

$UHID_CPU (0x02)

Uses information about your processor(s). Note that $UHID_CPU flag reduces the function speed.

$UHID_HDD (0x04)

Uses information about the installed hard drives. Any change in the configuration disks will change ID returned by this function. Taken into account only non-removable disks with an ATA or SATA interfaces.

The most optimum variant - $UHID_MB + $UHID_BIOS.

The sequence of obtaining hardware information:

Motherboard (

IdentifyingNumber + Name + SKUNumber + UUID + Vendor + Version)

+

BIOS (IdentificationCode + Manufacturer + Name + SerialNumber + SMBIOSMajorVersion + SMBIOSMinorVersion)

+

Processors (CPU1 (Architecture + Family + Level + Manufacturer + Name + ProcessorId + Revision + Version) + CPU2 (...) + ...)

+

HDDs (HDD1 (SerialNumber) + HDD2 (...) + ...)

 

#Include <Crypt.au3>
#Include <WinAPI.au3>

Global Const $UHID_MB = 0x00
Global Const $UHID_BIOS = 0x01
Global Const $UHID_CPU = 0x02
Global Const $UHID_HDD = 0x04
