If your PC is running Windows 10, it will stop receiving security updates after 14 October 2025. That means your device will still switch on and run as usual, but it won’t be protected against new viruses, malware or online threats. Over time, software developers will also stop supporting older systems, which can lead to compatibility issues with apps and slower performance.

For businesses, this is even more serious. Running outdated software can create compliance risks, make it harder to pass audits and leave you open to costly data breaches.

The safest option is to upgrade to Windows 11 or move to a new PC that supports it. Acting early avoids disruption and gives you time to prepare properly.
