Just run "uuid" as needed. – Alain O'Dea Jun 5, 2013 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, 2020 at 21:39 for folks running this on


    Git Bash

, stick this into a function in


    .bashrc


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

. Invoke it by just typing


    guid

and hitting


    Enter

. – Dut A. Jan 29, 2021 at 19:00 Now even


    powershell -command new-guid

, if I am may copy answer from mentioned cross-site dupclicate. – bogec Feb 7, 2021 at 17:45

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.

                This does NOT generate a GUID. It just shows an existing guid. DO NOT USE this if you want a unique GUID

                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

                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).

                Is it not available as a seperate download, as I have no use for the SDK or for Visual Studio.

                @Zubair: Install SDK, get uuidgen, uninstall SDK. Anything else is a copyright violation.

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 ... 
I found that uuidgen.exe is present inside my C:\Program Files (x86)\Windows Kits\10\bin\10.0.19041.0\x64 directory, probably because of some components that I have installed along with Visual Studio.
So I simply added C:\Program Files (x86)\Windows Kits\10\bin\10.0.19041.0\x64 to my PATH and now it's easy to remember to type uuidgen like I'm used on macOS instead of having to remember a long command.
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;
    UuidCreate(&id);
    StringFromCLSID(&id, &str);
    wprintf(L"%ls\n", str);
You can use the Windows Subsystem for Linux, eg install Ubuntu -
Welcome to Ubuntu 22.04 LTS (GNU/Linux 5.10.16.3-microsoft-standard-WSL2 x86_64)
$ uuidgen
(prints a uuid)
