Common problems buyers face include:
- Purchasing Windows 11 Pro when Home would have been sufficient

What Is a Windows 11 Product Key
A Windows 11 product key is a 25-character alphanumeric code that verifies your operating system as genuine. Once activated, Windows unlocks all features, receives updates, and removes activation restrictions.
Without activation, Windows 11 will continue to run but with limited personalization and ongoing system reminders.
