On 14 October 2025, Microsoft will officially end support for Windows 10. From this date, anyone using this operating system will no longer receive updates, bug fixes or security patches. As such, any new weaknesses discovered will remain unaddressed, leaving those using this software more exposed to cyber-crime.
Why does this matter?
These risks are not theoretical. When Windows 7 reached its end of support in January 2020, experts observed an increase in attacks targeting obsolete systems. The UK’s National Cyber Security Centre (NCSC), part of GCHQ, warned users at the time:
“We would urge those using the software after the deadline to replace unsupported devices as soon as possible… and not to use it for accessing bank and other sensitive accounts.”*
As the NCSC has previously highlighted, unsupported operating systems are a prime target for cybercriminals because they present known, unpatched vulnerabilities, an easy opportunity to spread ransomware, steal sensitive data, and disrupt businesses.
Why should you upgrade your operating system?
When an operating system no longer receives security patches, it becomes unsafe. Hackers know this and will deliberately search for outdated systems. The most likely risks include:
- Ransomware – attackers can lock your files and demand money to restore access.
- Data theft – sensitive or personal information can be stolen and sold.
- Business risk – a single outdated machine can give criminals a way into your entire network.
There’s still time to be prepared!
The good news is you don’t need to be an IT expert to protect yourself. Take action by:
- Upgrading to Windows 11
- The most reliable option, ensuring your device continues to receive updates.
- Before upgrading, check that your key programs still work on Windows 11.
- Buy extended Support (for Businesses)
- Microsoft will sell extra updates for Windows 10, but only for a limited time and with costs rising every year.
- This is best treated as a short-term solution.
- This special version is designed for equipment like medical or factory systems and will continue receiving updates for a time
You may also consider purchasing cyber security insurance. While individuals may be able to access some cover through existing policies, businesses can purchase separate insurance to help with financial losses and recovery costs in the event of an attack.
In 2020, the NCSC warned UK users that Windows 7 would become dangerous to use. The same pattern is likely to repeat when Windows 10 reaches end of support in 2025, except on a much larger scale as Windows 10 is far more widely deployed.
By failing to upgrade, you could leave your system wide open to attack. Hackers don’t need much time to find and exploit outdated software, but it only takes a few minutes to protect yourself by planning your upgrade today.
