Windows 10 end of support: what to do now
Microsoft ended support for Windows 10 on 14 October 2025. The computer keeps working, but Windows 10 no longer gets security fixes unless it is enrolled in Extended Security Updates. That matters most on a computer used for email, banking and shopping. Here are the options, in the order worth checking.
Keep your files safe first
Whatever you choose, back up first. An upgrade, a reinstall and a new computer all put your files at risk if the only copy is on this PC. Check the backup by opening a few files from it, ideally on another device.
- Documents, photos and anything on the desktop
- Email, if it is stored on the computer rather than online
- Browser bookmarks and saved passwords
- Installers, licence keys and sign-ins for the programs you rely on
Check whether this PC can run Windows 11
Microsoft's PC Health Check app tells you whether the computer meets the Windows 11 requirements. Windows Update in Settings may also show whether the upgrade is offered. If the PC passes, the upgrade from Windows 10 is free and normally keeps your files and apps.
If it fails, the reasons listed matter. A security setting that is switched off can often be turned on. An unsupported processor cannot be changed without replacing major parts, which is rarely worth it.
Upgrade to Windows 11
Before upgrading, back up, free up some storage and check that your printer and any specialist software support Windows 11. Keep a laptop on its charger for the whole upgrade.
Afterwards, open the programs you use every day and print a test page. Problems tend to show up in the first few days of normal use, so note anything odd rather than working around it.
Extended Security Updates for more time
Consumer Extended Security Updates, or ESU, keep a Windows 10 PC getting security updates until 12 October 2027. Microsoft's Australian page lists three ways to enrol: free if you sync your PC settings, by redeeming 1,000 Microsoft Rewards points, or a one-time purchase of AU$44.95. Those are Microsoft's terms and price, checked on 23 September 2026.
The PC needs Windows 10 version 22H2 with the latest updates, and you sign in with a Microsoft account that is an administrator on that PC. Enrolment starts from Windows Update in Settings. ESU only buys time: it brings security fixes, no new features, and it ends in October 2027.
Microsoft does not make unsolicited calls to fix your computer. Treat any call, email or pop-up about Windows 10 ending as a scam, and enrol only through Settings on your own PC.
Replace the computer
If the PC cannot run Windows 11 and is also slow or unreliable, a replacement may be the better use of money. Compare the full cost, including moving your files and setting up printers and programs.
Keep the old PC until your files and everyday tasks are confirmed on the new one. Then plan how its storage will be cleared before it is sold, given away or recycled.
Or keep the hardware and switch to Linux
A computer that runs well but fails the Windows 11 check can often run a Linux desktop instead, with a web browser, email and office programs. It suits people whose programs run in a browser or have Linux versions. Check your must-have programs before deciding.
Where Mark can help
Mark can check whether your PC qualifies, back up your files, run the upgrade or ESU enrolment with you, or set up a replacement or Linux. Onsite help is on demand or by booking, and remote help can suit a PC that starts and is online. The work and cost are agreed before anything starts.
