How to Deactivate Windows 10: A Step-by-Step Guide to Disabling Your OS

Deactivating Windows 10 can be straightforward if you know the steps. Essentially, you’ll be accessing the command prompt to input a specific command that will deactivate your Windows 10 license. This means your Windows copy will no longer be activated, useful if you’re transferring a license to another machine or troubleshooting.

How to Deactivate Windows 10

In this guide, you’ll learn how to deactivate your Windows 10 license using the command prompt. This process involves a few steps but is quite easy to follow.

Step 1: Open Command Prompt as Administrator

First, you’ll need to open the Command Prompt with administrative privileges.

Right-click the Start button and select "Command Prompt (Admin)" or "Windows PowerShell (Admin)." This ensures you have the necessary permissions to deactivate the license.

Step 2: Enter the Command

Type slmgr /upk and press Enter.

The ‘upk’ part stands for ‘Uninstall Product Key.’ This command will remove the product key from your system, effectively deactivating Windows 10.

Step 3: Confirm Success

You should see a message saying "Uninstalled product key successfully."

If the message doesn’t appear, try running the command again. Sometimes it may take a moment for the change to register.

Step 4: Optional – Clear Product Key from Registry

For added security, you can clear the product key from the registry by typing slmgr /cpky and pressing Enter.

This will ensure that the key is completely removed from the system, making it impossible to retrieve it later.

Step 5: Restart Your Computer

Finally, restart your computer to apply the changes.

Rebooting ensures that all changes are correctly saved and that your system recognizes the deactivation.

After completing these steps, your Windows 10 should be deactivated. This means you’ll see a watermark on your desktop saying "Activate Windows," and some features might be limited.

Tips for Deactivating Windows 10

• Make sure to back up any important data before making changes to your system settings.
• If you’re transferring your license to another computer, make sure you have your product key handy.
• Use the slmgr /dlv command to view detailed license information before deactivating.
• Note that deactivating Windows 10 does not uninstall it; it just removes the activation.
• If deactivation fails, try running Command Prompt as an administrator again.
