How to Find Your Windows 10 Product Key

Finding a Windows 10 product key can be useful when reinstalling Windows, transferring a retail license, or documenting software purchases.

Check Activation

Go to Settings > Update & Security > Activation and review the activation information for your installation.

Look at Your Purchase Records

Retail Windows purchases may include a product key in an email, product card, packaging, or other purchase documentation.

OEM Computers

Many computers that shipped with Windows include an OEM license associated with the device. The key may be stored in firmware rather than printed on a sticker.

Digital Activation

A digital license can allow Windows to reactivate without manually entering a product key after a supported reinstall.

Always keep legitimate license and purchase records. Avoid websites offering questionable or unauthorized product keys.
