How can I get my windows 10 activation key?

To retrieve your Windows 10 activation key, you can try the following methods:

1. Check the Settings App: Go to Settings > Update & Security > Activation. If your Windows is activated, you might see the activation status and the last five characters of your product key.
2. Using Command Prompt: You can run the following command in Command Prompt to view the last five digits of your product key:

   This command may show the original product key if it is stored in the BIOS/UEFI.
3. Look for a Physical Copy: If you purchased a physical copy of Windows 10, the activation key is usually found on a sticker inside the box or on the card that came with it.
4. Email Confirmation: If you purchased Windows 10 online, check your email for a confirmation message that may contain your activation key.
5. Contact Microsoft Support: If you are unable to find your key through the above methods, consider reaching out to Microsoft Support for assistance.

Keep in mind that if your device came with Windows pre-installed, the key may be embedded in the firmware, and you might not have direct access to it.
