How to Generate a Globally Unique Identifier (GUID) in Windows 11

This article explains how to generate a Globally Unique Identifier (GUID) in Windows 11.

A GUID is a unique 128-bit value that identifies resources like interfaces, objects, and other items in the Windows operating system. It is essentially a unique identifier assigned to a specific object or entity, and it is used by various applications and services to ensure that they are working with the correct resource.

Windows lets you generate a new GUID using the Windows Command Prompt or Windows PowerShell.

GUIDs are also useful in scenarios where there is a need to generate a unique identifier for each object or entity that can be reliably replicated across different systems or applications. This helps avoid conflicts or duplication of resources, which can cause issues in the functioning of the system or application.

Generate a new GUID using the Windows Command Prompt

As mentioned above, users can create a new GUID in Windows using the Command Prompt or PowerShell.

Below are steps to generate a new GUID in Windows 11.

First, open the Windows Terminal and select Command Prompt.

Then, run the command below to generate a new GUID without a bracket.

powershell [guid]::NewGuid()​

To create one with a bracket, run the command below.

powershell '{'+[guid]::NewGuid().ToString()+'}'

Generate a new GUI with Windows PowerShell

Another way users can generate a new GUID is to use Windows PowerShell.

First, open the Windows Terminal and select PowerShell.

Then, run the command below to generate a new GUID without brackets.

[guid]::NewGuid()

To generate one with brackets, run the command below.

'{'+[guid]::NewGuid().ToString()+'}'

That should do it!
