If you’re planning to reinstall Windows 10 or move it to a new computer, you can reuse your Windows 10 key. By deactivating it on the old device and entering it on the new one, you can keep your software legally licensed. Here’s how you do it step by step.
How to Reuse Windows 10 Key
In this guide, you’ll learn how to deactivate your Windows 10 key on an old device and activate it on a new one. These steps will ensure that your key is valid and your Windows stays activated.
Step 1: Deactivate the Windows 10 Key on the Old Device
Open Command Prompt as an administrator and run the command slmgr.vbs /upk.
This step removes the product key from the current computer, making it available for use on another device. Ensure you have administrative rights to perform this action.
Step 2: Install Windows 10 on the New Device
Use a Windows 10 installation media, such as a USB drive or DVD, to install the operating system on your new device.
During installation, you’ll be prompted to enter your product key. If you don’t have the installation media, you can create one using the Media Creation Tool from Microsoft’s website.
Step 3: Enter the Windows 10 Key During Installation
When prompted, enter the product key you deactivated from the old device.
This activates Windows 10 on the new device, linking it with the key. If you skip this step during installation, you can enter the key later in the "Activation" settings.
Step 4: Activate Windows 10 via the Internet
Once Windows 10 is installed on the new device, connect to the internet. Go to Settings > Update & Security > Activation and click on "Activate."
Connecting to the internet allows Windows to verify the key with Microsoft’s servers. Ensure your new device has a stable internet connection for this step.
Step 5: Verify Activation
Check that your Windows 10 installation is activated by going to Settings > Update & Security > Activation. It should display "Windows is activated with a digital license."
This confirms that your Windows 10 is legally activated on the new device. If there are any issues, troubleshoot according to the error messages displayed.
After completing these steps, your Windows 10 key should be successfully transferred to your new device. Your old device will no longer have an activated copy of Windows 10, ensuring your key is used legally.
Tips for Reusing Windows 10 Key
- Backup Important Data: Before deactivating Windows on your old device, back up all important files to avoid data loss.

- Use the Correct Version: Ensure the version of Windows 10 you install on the new device matches the version your key is for (e.g., Home, Pro).
- Contact Support: If activation fails, contact Microsoft Support for assistance. They can help resolve any issues with your key.
