Ensuring your organisation uses genuine Microsoft software protects you from the myriad of potential risks posed by using unlicensed software - risks that could end up costing you hugely down the road!
I'm not sure why so many are referencing the agricultural sector but I saw good information on how to ensure I am receive original Microsoft products which is coincidentally exactly what I am purchasing today.
It is foolish for any business (or individual for that matter) to utilise unlicensed software and forgo the protection that comes with a genuine Microsoft product. Genuine Microsoft products also offer added value e.g. Skype and OneDrive cloud storage. A no-brainer really.
