How can I generate a UUID from the command line in Windows XP? Something like "uuid" or "uuidgen" in Linux.


If powershell is installed this is a simple commandline to get a guid

powershell -Command "[guid]::NewGuid().ToString()"

  • You can make it a reusable command within PowerShell with. function uuid { [guid]::NewGuid().ToString() }. Just run "uuid" as needed. – Alain O'Dea Jun 5 '13 at 17:33
  • I put this line in guid.bat in a PATH folder so it works in regular command prompt and PowerShell. – biscuit314 Jan 13 at 21:39

Drop the following code into a new file name uuid.vbs

set obj = CreateObject("Scriptlet.TypeLib")
WScript.StdOut.WriteLine obj.GUID

Then you can run it from the command line like so:

cscript //NoLogo uuid.vbs

This will work on pretty much any computer that has the Windows Scripting Host installed - which certainly includes anything later than Windows 2000, and probably includes 95/98/ME as well... though I don't have an instance handy to check.

If you need to remove the braces, replace the last line with this

WScript.StdOut.WriteLine Replace(Replace(obj.GUID,"{",""),"}","")

    Funny how in Windows it's only unique to each planet, but in Unix and related systems it's unique throughout the entire universe. – Bratch Jun 23 '10 at 19:45

You can also use this command in a command prompt:
wmic path win32_computersystemproduct get uuid

  • seems like it's only good for 1 guid – drzaus Jan 15 '14 at 21:24

    This does NOT generate a GUID. It just shows an existing guid. DO NOT USE this if you want a unique GUID – Air2 Mar 27 '14 at 13:55

To copy a new GUID to the clipboard, use this command :

cmd /c powershell.exe -Command "[guid]::NewGuid().ToString()|Set-Clipboard"

You can run the command straight from the Start, Run dialog ( WinLogo + R ), then use Ctrl+V to paste the generated GUID, which WILL also save it into your Run dialog history - aka if you use it often it will pop-up as suggestion there ...

  • Do you know where I can download this "uuidgen" from? – appshare.co Jun 23 '10 at 11:24
  • It comes with Visual Studio - I'd expect it to come with the express edition of Visual C++ which I believe is a free download, as well – Rowland Shaw Jun 23 '10 at 11:34

    msdn.microsoft.com/en-us/library/aa373930%28VS.85%29.aspx says that the uuidgen utility (Uuidgen.exe) is automatically installed when you install the Platform Software Development Kit (SDK). – Mehper C. Palavuzlar Jun 23 '10 at 11:35
  • Is it not available as a seperate download, as I have no use for the SDK or for Visual Studio. – appshare.co Jun 23 '10 at 11:36

    @Zubair: Install SDK, get uuidgen, uninstall SDK. Anything else is a copyright violation. – harrymc Jun 23 '10 at 11:48

If the system OS does not have Windows SDK but does have a C compiler with mingw-w64 toolchain then compile this small program to generate random GUID. Imported functions are UuidCreate (rpcrt4.lib) to create random UUID and StringFromCLSID (ole32.lib) to convert UUID to wide string.

#include <Windows.h>
#include <stdio.h>

 * int UuidCreate(GUID *id);
 * int StringFromCLSID(GUID *id, wchar_t **str);
 * Libraries: Rpcrt4.lib Ole32.lib

int main(void)
    GUID id;
    wchar_t *str = NULL;

    StringFromCLSID(&id, &str);
    wprintf(L"%ls\n", str);

Now in powershell, you can use built in New-GUID function:

For /f "tokens=* delims= " %%a in ('powershell -noP -c "& {(New-GUID).GUID}"') do set "GUID=%%~a"
| improve this answer | |
  FOR /F %a IN ('POWERSHELL -COMMAND "$([guid]::NewGuid().ToString())"') DO ( SET NEWGUID=%a )
