Have you ever needed a unique ID number for a file, app, or project? A GUID (Globally Unique Identifier) is like a special ID that Windows and many apps use to make sure things are one-of-a-kind.

A GUID looks like a long string of letters and numbers, and it’s very unlikely that two GUIDs are ever the same. This helps your computer keep track of different things without mixing them up.

You can easily create a new GUID on your Windows 11 computer using either the Command Prompt or PowerShell. Both are tools where you type commands to make your computer do things.

What is a GUID?

A GUID is a 128-bit number (that’s a very big number!) that Windows uses to identify things like software components, files, or settings. Think of it like a fingerprint that’s unique to each item.

How to Open Command Prompt or PowerShell

Before generating a GUID, you need to open the Command Prompt or PowerShell:

• How to open Command Prompt in Windows 11
• How to open PowerShell in Windows 11

Generate a GUID Using Command Prompt

Follow these easy steps:

1. Open Windows Terminal and choose Command Prompt from the dropdown menu.
2. Type the following command and press Enter to get a GUID without brackets:

powershell [guid]::NewGuid()

If you want the GUID with curly brackets around it, type this command instead and press Enter:

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

Generate a GUID Using PowerShell

Here’s how to do it in PowerShell:

1. Open Windows Terminal and pick PowerShell from the dropdown menu.
2. Type this command and hit Enter to get a GUID without brackets:

[guid]::NewGuid()

To get a GUID with brackets, use this command:

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

Why Use GUIDs?

GUIDs are helpful because they make sure every item or resource has a unique ID. This stops confusion or errors when different parts of your computer or apps try to use the same name or number.

Summary

• GUIDs are unique ID numbers used by Windows and apps to identify things safely.
• You can easily create GUIDs using either Command Prompt or PowerShell in Windows 11.
• Generating GUIDs helps avoid mix-ups and keeps your system running smoothly.

### Explanation for everyday users:

– **GUID** is just a special code that your computer uses to keep track of things uniquely.
– You don’t need to install anything special; just open tools already in Windows.
– The commands are simple to type and instantly give you a new unique ID.
– Links included show how to open Command Prompt and PowerShell if you’re unsure.
