Where to Redeem a Windows Product Key on Windows 10 & 11

Method 1 – Redeem Via Windows Settings (Recommended)

If you already have your Windows key, the easiest and most reliable way to activate it is through the built-in Settings menu. Whether you’re on Windows 10 or 11, Microsoft provides a direct way to input your key and validate it securely.

For Windows 11 Users:

1. Open Settings from the Start Menu or press Win + I.
2. Navigate to System → Activation.
3. Click Change product key.
4. Enter your 25 character Windows key and follow the on-screen prompts.

For Windows 10 Users:

1. Press Win + I to open Settings.
2. Go to Update & Security → Activation.
3. Click Change product key.
4. Enter your key and complete the activation process.

Good to Know:

• This method works for retail, OEM, and digital license keys.
• Make sure your device is connected to the internet during activation.
• If activation fails, you might see an error code (we’ll cover how to fix those later in this guide).

This method is recommended because it directly links your license to your Microsoft account or device hardware, making future reinstallations seamless.

Method 2 – Redeem Using Microsoft Account / Website

If you purchased your Windows key online or received it as part of a digital bundle, you can also redeem it directly through Microsoft’s web platform or the Microsoft Store.

This method is useful when you’re redeeming a key before installing Windows, or if you’re managing multiple licenses tied to your Microsoft account.

Redeem via Microsoft Store (For App/Game or Digital License Codes)

1. Open the Microsoft Store on your PC.
2. Click your profile icon in the upper right corner.
3. Select “Redeem a code” from the dropdown.
4. Paste or type in your 25 character product key.
5. Follow prompts to apply it to your account.

Note: This method is typically used for redeeming digital game or app codes, but some Windows digital licenses can also be activated this way if tied to a Microsoft Store purchase.

Redeem via Web Portal (For Any Windows Product Key)

1. Go to microsoft.com/redeem.
2. Sign in with your Microsoft account.
3. Enter your Windows product key and submit.
4. If eligible, the license will be linked to your account and ready for future activation.

This is especially helpful if you plan to use the license on a new device later. It ties the key directly to your Microsoft credentials.

Pro Tip:

Avoid using the Xbox or Office redemption interfaces, as they do not support Windows product keys. Always verify that you’re redeeming under the correct Microsoft service.

Method 3 – Command Line (slmgr) Activation

Ideal for IT professionals, power users, or those working on headless systems, this method activates Windows via Command Prompt using Microsoft’s built-in slmgr (Software Licensing Manager) tool.

Common slmgr Commands

You can activate Windows using these two basic commands:

bash

slmgr /ipk YOUR-25-CHAR-KEY

slmgr /ato

• /ipk: Installs your Windows product key.
• /ato: Activates Windows online using Microsoft’s activation servers.

Example:

bash

slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

slmgr /ato

These commands must be run as Administrator. Right click on the Start button → Windows Terminal (Admin) or Command Prompt (Admin).

Expert Insight

This method is especially useful when:

• Performing batch activation across multiple devices
• Managing non-GUI environments (e.g., virtual machines or servers)
• Troubleshooting failed GUI activations (bypassing UI errors)

Check Activation Status

To verify whether your activation worked or diagnose licensing issues, use:

bash

slmgr /dli

slmgr /dlv

• /dli: Displays basic license info (good for quick checks).
• /dlv: Displays detailed license data, including remaining activation attempts and errors.

Tip: If you receive error codes (e.g., 0xC004F050), cross reference them on Microsoft’s official documentation for solutions.
