What is a Windows Product Key?

A Windows product key is a 25-character code used to activate your Windows operating system. It typically looks like this: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.

There are several types of Windows product keys:

  • Retail keys (purchased from stores)

  • OEM keys (pre-installed on new computers)

  • Volume license keys (for businesses)

  • Digital licenses (linked to your Microsoft account)
