Microsoft ended regular support for Windows 10 on 14 October 2025. Computers running it will keep working, but they no longer receive routine security updates unless the owner uses a limited paid or special extended programme. Over time, that makes them a bigger target for attackers and less compatible with new software.
Step 1: find out what you have
List every computer in the school, office or home. Check the Windows version in Settings, under System, About.
Step 2: check if it can upgrade
Many Windows 10 computers can move to Windows 11 for free if they meet the hardware requirements. Windows' update settings will tell you. If a machine is too old, you have other choices.
Step 3: choose a path
- Upgrade if the computer is eligible.
- Replace the oldest machines first, starting with those used for money, records or exams.
- Switch the operating system on old but working computers to a lightweight Linux, which can give them years more life for browsing and learning.
- Extend support with the official extended security update options where available, as a short-term step.
Step 4: protect while you decide
Back up important files, keep your browser updated and avoid using an unsupported computer for banking.
