unique ID for System(PC)

[trancexx]

It appears that UUID information is stored at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Mssmbios\Data.

But...

At system startup all informations from there are collected by mssmbios.sys (that is SMBIOS driver).

Then something happens. This driver deletes (zeroes out) few data fields. UUID section inclusively, probably for security reasons.

All that is collected is stored in a special buffer.

Question is how to acces data in that buffer. WMI is the answer and was the only method until kernel32.dll got two functions EnumSystemFirmwareTables() and GetSystemFirmwareTable().

How do I know this? I read document named SMBIOS.doc

Find it, it's 112KB doc file. When you are finished reading, you will probably say: "So that's how WMI works! "

I wouldn't be disappointed yet.

Supported Operating Systems: Windows Vista, Windows XP Professional x64 Edition

So your theory wouldn't work with Windows XP SP2 and below.

For simplicity sake, use DriveGetSerial.

The only issue you'll run into that UUID usually solves is if it's cloned in a virtual environment and passed around (DriveGetSerial won't help you there).

From the forums

#Include <WinAPI.au3>

MsgBox(4096, "Generate Guid", _CreateGuid())

Func _CreateGuid()
    Local $Guid = DllStructCreate($tagGUID)
    $Result = DllCall("OLE32.DLL", "dword", "CoCreateGuid", "ptr", DllStructGetPtr($Guid))
    $Result = _WinAPI_StringFromGUID(DllStructGetPtr($Guid))
    Return $Result
EndFunc

Hey, Thanks! You saved my day right now!

spyro that is not UUID that should be saving you in the context of this thread. That 'string' changes for every next call. Edited April 27, 2009 by trancexx

MAC address would be a start. If you want to get hold of it (and lots of other interesting information), you should start by taking a look at this message : http://www.autoitscript.com/forum/index.ph...st&p=513225

Note the comment for ProgAndy (two posts latest) about increasing the size of the structure on line 109. You could take the output from _IPH_Capture() and parse it in to an XML DOM for further processing.

Universally unique identifier (UUID) for this product. A UUID is a 128-bit identifier that is guaranteed to be different from other generated UUIDs. If a UUID is not available, a UUID of all zeros is used.

http://msdn.microsoft.com/en-us/library/aa394105(VS.85).aspx

I'm using the following code:

Func _GetUUID()
    Local $oWMIService = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\localhost\root\cimv2")
    If Not IsObj($oWMIService) Then
        Return SetError(1, 0, -1)
    EndIf
    Local $oSysProd = $oWMIService.ExecQuery("Select * From Win32_ComputerSystemProduct")
    For $oSysProp In $oSysProd
        Return SetError(0, 0, $oSysProp.UUID)
    Next
    Return SetError(2, 0, -1)
EndFunc

InputBox('UUID', 'Computer Universally Unique Identifer', _GetUUID())

I get:

00000000-0000-0000-0000-000000000000

Does anyone have an idea how to force one to be generated?

Is there another method of getting or creating a Unique System ID?

Thanks.
