Windows Enterprise Editions are not available for sale pre-installed, or to the genral public - they are only sold in bulk to organisations for use on their own machines.
Your Key is the KMS Volume Licensing key - which must be activated against the issuing organisation's own servers - there is no data in the rport which sugests that such an organisation has ever touched this PC.
Is there a COA sticker on teh machine? If so, for what version and edition of Widows is it valid? - the sticker will be on the base, or inside the battery compartment.
...and your installation of Office is also a Volume Licensed edition - which will be counterfeit, unless provided by your employer or college.
