How the upgrade to Windows 11 Pro works

  • Buy an upgrade key. Purchase the Windows 11 Pro key from us, delivered by email once payment is received.
  • Open Settings. In Windows, navigate to System and Activation.
  • Change the product key. There, select the option to change the product key and enter the new Pro key.
  • Complete the upgrade. Windows unlocks the Pro features. Your files, programs and settings are preserved.

When the Pro upgrade is worth it

Switching from Home to Pro is worth it as soon as you need one of the Pro features: BitLocker for drive encryption, Hyper-V for virtualization, Remote Desktop Server for access from outside, or connecting to a company network.

The upgrade is far more convenient than a reinstallation. You keep your configured system entirely, and the switch takes just a few minutes. If you are starting from Windows 10, the device should additionally meet the Windows 11 hardware requirements.
