Generates a unique hardware identifier (ID) for local computer
#include <WinAPIDiag.au3>
_WinAPI_UniqueHardwareID ( [$iFlags = 0] )
| $iFlags | [optional] The flags that specifies what information would be used to generate ID. This parameter can be one or more of the following values. $UHID_MB - Uses information about your motherboard. This flag is used by default regardless of whether specified or not. $UHID_BIOS - Uses information from BIOS. $UHID_CPU - Uses information about your processor(s). Note that $UHID_CPU flag reduces the function speed. $UHID_HDD - 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. $UHID_All - The sum of all the previous flags. |
| Success: | The string representation of the ID. @extended returns the value that contains a combination of flags specified in the $iFlags parameter. If flag is set, appropriate information is received successfully, otherwise fails. The function checks only flags that were specified in the $iFlags parameter. |
| Failure: | Empty string and sets the @error flag to non-zero. |
This function uses the Windows Management Instrumentation (WMI).
