As reported by ZDNet around half a million computers used by the NHS are still running the outdated Microsoft Windows 7 operating system, missing the government’s own target of upgrading all PCs and laptops by January this year. And the real figure could be even higher. According to government figures, at least a third of the UK health service’s PCs are still running Windows 7.
If organisations choose to pay for extended support for Windows 7 then that is their prerogative, however this must be dealt with sensitively and a designated date for updating to a newer operating system (OS) is strongly advised. It is never a good idea to use an out of date OS even with extra paid-for support, as it may harm your network should future flaws be found. Legacy software is usually the first reason for not doing so, but updating your software to work with Windows 10 will cost far less than having another WannaCry hit the NHS.
