How to Find Your Windows 11 Product Key
If you need to reinstall Windows 11, verify a license, or document your software assets, you may want to find your Windows product key. The method available to you depends on how Windows was originally licensed.
Check Your Windows Activation Status
Open Settings > System > Activation to see whether Windows is activated and to review information about your digital license.
Use Command Prompt
On some systems, the original OEM key stored in the computer’s firmware can be displayed using Command Prompt. Open Command Prompt as administrator and run the appropriate Windows licensing command.
Check the Original Purchase
If Windows was purchased separately, the product key may be included in the original email, packaging, certificate of authenticity, or purchase documentation.
Digital License vs Product Key
Many modern Windows installations use a digital license rather than requiring you to enter a product key during installation. In that situation, Windows may reactivate automatically when the device connects to the internet.
Before reinstalling Windows, it is a good idea to confirm your activation status and keep your original purchase information available.
