What operating system am I using? From Windows to iOS, discover which OS your device is running
If you're looking to upgrade your phone or computer, we've explained how to find out which operating system you're on
Whenever a new operating system is released, or one reaches the end of its life, it can be confusing to know whether you should be upgrading or not.
Running the most up-to-date operating system, whether it’s on your mobile, tablet or PC, not gives you access to all the latest features, it also protects you and your files from security flaws.
Software is constantly evolving and hackers, as well as security experts, are always are on the hunt for vulnerabilities that could be exploited. When these are discovered, the software manufacturers release what’s known as a “patch” which is an update that plugs the gap.
At other times, the particular operating system is so old that its manufacturer stops issuing updates, leaving it at risk without a fix. In this instance, the only way to protect yourself is to stop using that operating system by upgrading or abandoning the device.
The most recent example of this is Microsoft pulling support for Windows 7.
Since 14 January 2020, Microsoft has stopped issuing regular updates for all computers on the Windows 7 network, which includes security patches and all technical assistance.
Such is the potential threat of using this now out-of-date software, the National Cyber Security Centre (NCSC) – the public-facing arm of the UK government’s intelligence agency GCHQ – is warning people running Windows 7 to stop using online banking, emails and other sensitive accounts as soon as possible to avoid being left vulnerable to hackers.
Out-of-date Windows 7 devices were also said to have played a major role in the WannaCry scandal that hit the NHS in 2018, just to give you the potential scale of the risk. Until 2016, upgrading to Windows 10 from Windows 7 was free, however it now costs £120 for Windows 10 Home, £220 for Windows 10 Pro and £339 for Windows 10 Pro for Workstations.
