It's always best to be on the right side of the law. MS is forgetting that not everyone lives in the USA. Some of us are in Africa where data and therefor updates of operating systems cost a fortune. When they removed the ability to buy and have my software local after purchase they alienated me.
One of the easiest ways to tell if you are purchasing authentic Microsoft software is to check the label - authentic Microsoft software will carry a Genuine Microsoft Label (GML). This label helps users identify which edition of Windows has been preinstalled on their devices and can usually be found on the back or bottom of the devices. In September 2017 Microsoft released a new GML design to prevent fake duplicates form being created - is features a holographic image, holographic micro text and colour shifting ink which changes from one colour to another when looking at it from various angles. These labels also include a handy “tamper evident” feature which appears upon the label being removed. When it comes to Windows phones and tablets, these labels may not always be attached to the device itself so Microsoft has suggested various other measures you can take to ensure the software is authentic.
