Still running Windows 8.1 or 7?  It’s time to upgrade to 10 or 11!

While you could continue to use your PC running an older version of Windows
Without continued software and security updates, it will be at greater risk for viruses and malware. Going forward, the best way for you to stay secure is on Windows 10 or 11. And the best way to experience Windows 10 or 11 is on a new PC. While it is possible to install Windows 10 on your older device, it is not recommended.
