Ready to uncover the secret identity of your Windows 11 machine? Let's dive in!

Step 1: Unleashing the Power of the Command Prompt

The Command Prompt is a versatile tool in Windows, and it holds the key to finding your Computer ID. Here's how to use it:

Open the Command Prompt: There are several ways to do this:
- Press the Windows key on your keyboard, type cmd, and press Enter.
- Right-click the Start button and select "Terminal (Admin)" or "Windows PowerShell (Admin)".
- Press Windows key + R, type cmd, and press OK.
Enter the Magic Command: Once the Command Prompt window appears, type the following command exactly as it's written and press Enter:
wmic csproduct get UUID
Behold Your Computer ID! The Command Prompt will display a string of alphanumeric characters. This is your computer's Universally Unique Identifier (UUID), which serves as its unique hardware ID. It will look something like this:
UUID F4B9D4B3-A2C1-47E9-B8F2-9A3C5E7D1F0A
Note: This method provides the most direct way to find the system's hardware UUID.

Step 2: Exploring System Information

Windows 11's System Information tool provides a comprehensive overview of your computer's hardware and software configuration, including the Computer ID.

Launch System Information: You can access it in a few ways:
- Press the Windows key, type system information, and press Enter.
- Press Windows key + R, type msinfo32, and press OK.
Navigate to System Summary: In the System Information window, make sure "System Summary" is selected in the left-hand pane.
Locate the Item: In the right-hand pane, scroll down until you find the item labeled "System UUID". The value next to it is your computer's unique identifier.

Tip: You can easily copy this information by right-clicking on the "System UUID" value and selecting "Copy".

Step 3: Delving into PowerShell

PowerShell is another powerful command-line shell and scripting language in Windows that can also reveal your Computer ID.

Open PowerShell: Similar to the Command Prompt, you can open PowerShell in several ways:
- Press the Windows key, type powershell, and press Enter.
- Right-click the Start button and select "Terminal" or "Windows PowerShell".
- Press Windows key + R, type powershell, and press OK.

Execute the Command: In the PowerShell window, type the following command and press Enter:

PowerShell
Get-CimInstance -ClassName Win32_ComputerSystemProduct | Select-Object -ExpandProperty UUID
    

Your Computer ID Revealed: PowerShell will output your computer's UUID, which is the same as the one you found using the Command Prompt.

Insight: PowerShell offers more advanced scripting capabilities, making it useful for automating tasks related to system information retrieval.

Step 4: Utilizing Registry Editor (Advanced Users)

The Registry Editor contains low-level configuration settings for Windows and installed applications. While it does store the Computer ID, modifying the registry can be risky if not done correctly, so proceed with caution.

Open Registry Editor:
- Press Windows key + R, type regedit, and press OK.
- Click "Yes" if prompted by User Account Control.
Navigate to the Key: In the Registry Editor window, navigate through the following path in the left-hand pane:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography
Find the MachineGuid Value: Under the Cryptography key, look for a value named "MachineGuid" in the right-hand pane. The data associated with this value is your computer's unique identifier.

Caution: Avoid making any changes to other registry values unless you are absolutely sure of what you are doing. Incorrect modifications can lead to system instability.
