An Official of Microsoft warns the users, still using the Windows 7 version, about some problems they might face in future. He said those users can continue on the previous version at their own risk and peril. He also mentioned that their advancements to exploit Windows 10 may lead to security problems in older versions.
Windows 7 is no less secure than Windows 10 (it will be supported until 2020) and no less compatible with new hardware and software. In fact, its far greater market share means it is developers’ priority and has greater compatibility with legacy programmes and peripherals.
