"over 50 per cent of commercial devices were now on Windows 10."
Not sure exactly what they mean by "commercial devices". The photocopier? The coffee machine in the office kitchen? 50 per cent of the staplers? Are computers that dual boot Linux / Windows 10 counted as 50 per cent on Windows 10, or only if booted into Windows 50 per cent of the time? Perhaps 50 per cent of computers in the office that sneakily upgraded themselves to Windows 10 before we could stop them all?
