Starting Tuesday, Microsoft will stop providing standard free support for Windows 10, an operating system still used by millions of PC and laptop users worldwide.
Although Windows 11 was launched in 2021, September data shows that around 40% of global Windows users are still using Windows 10.
What’s Changing in Windows 10?
From October 14, 2025, Microsoft will no longer offer free software updates, security patches, or technical support for Windows 10.
Your PC will continue to work, but over time it will become increasingly vulnerable to viruses, malware, and other security threats. Microsoft recommends upgrading to Windows 11, which “meets current security standards by default.”
Security Risks
Continuing to use Windows 10 may make your system a target for hackers.
According to Which?, around 5 million UK users plan to continue using Windows 10.
Globally, using an outdated and unsupported system increases the risk of cyberattacks, data theft, and scams.
“Criminals will exploit weaknesses and try to steal your data,” says Lisa Barber, editor of Which? Tech magazine.
How to Reduce the Risk
The easiest solution is to upgrade to Windows 11, which is free for most PCs.
- PCs less than four years old are usually eligible.
- Minimum specifications: 4GB RAM, 64GB storage, and TPM 2.0.
- Microsoft provides a free tool to check if your Windows 10 PC can run Windows 11.
- Which? also offers an online tool to check processor compatibility.
If Your PC Can’t Upgrade
If your hardware does not support Windows 11, doing nothing increases the risk of malware and security threats. Options include:
- Extended Security Updates (ESU): Microsoft offers a one-year extended security update, protecting PCs until October 13, 2026.
- Free if you sync your settings with a Microsoft account.
- Otherwise, it costs $30 + tax or can be redeemed with 1,000 reward points.
Alternatives to Windows 11
For PCs that cannot upgrade:
- Install Linux:
- Free, secure, open-source OS with regular security updates.
- Popular and user-friendly version: Ubuntu.
- Back up your files, as installation may erase existing data.
- Requires a USB flash drive and following step-by-step installation guides.
- ChromeOS Flex:
- Google’s lightweight, browser-based OS.
- Free installation on supported PCs using a USB drive.
