Using a generic key can be helpful if you want to install or upgrade to a specific Windows 11 edition for evaluation or testing on a PC or virtual machine, or just don't have a digital license or your genuine product key currently available and you will activate later when able.

You can test Windows 11 before you deploy it to your organization or home. In this case, you can use a virtual machine such as Virtual Box or Hyper-V. You may find it a bad idea to enter your license product key you are using on the real computer to activate a virtual instance. It may have a limit on the number of activations.
