How to find your Windows license key in several ways:

1. If your Windows copy is activated using a digital license linked to your Microsoft account, you can retrieve it by logging in to your Microsoft account and checking the Devices section. The license key will be listed there.
2. If your Windows copy was activated using a product key, you can find it on the Certificate of Authenticity (COA) sticker attached to your computer or laptop. It is usually located at the bottom or side of your device. Be sure to check the sticker carefully as the key may be printed in small font or hidden behind a barcode.
3. You can also use third-party software such as Belarc Advisor or ProduKey to retrieve your license key. These programs scan your computer for installed software and display the license keys associated with them. However, use caution when downloading and using these programs as they may pose security risks or contain malware.
