The following script will read the UEFI stored Windows licensing key and show it – it then will attempt to activate Windows and probably even e.g. your Microsoft Office installation – this is not necessarily intentional by the script, rather then a coincidence that I discovered by using this script to activate Windows after it was automatically deployed from an image that had a pre-injected volume license key. Office likely got activated along with Windows.
In any case – it helps you to activate Windows or simply read out your license key.
