User Question: Windows 7 is a great operating system. Should we really go through the trouble of upgrading to Windows 10 if we are happy with the older version? Can we just upgrade some of our computers and not all of them?
Answered By a CTO: Yes, you should absolutely go through the process.
Make sure every single computer connected to your domain (and especially to the internet), is upgraded to Windows 10. In addition to some performance and visual enhancements, the most important reason to upgrade is to stay current with security updates. You should always make network security the top priority of any business.
Protect Against Ransomware
We have seen a huge increase in ransomware attacks. Ransomware not only targets application flaws, but can exploit vulnerabilities of an outdated operating system itself. You can easily keep software up-to-date. However, Microsoft will no longer be providing operating system updates for Windows 7 starting on January 1, 2020. So at that point, they won’t even be able to remedy or patch known security issues with the latest updates. That leaves your business extremely vulnerable to well-known attacks.
The Weakest Link
Furthermore, you won’t be able to protect your domain, even with the best firewalls and other security methods. Your entire network’s security is only as strong as its weakest link. All it takes is one vulnerable, out-of-date computer to open up your whole system to a cyberattack. You really do need to upgrade all of them in order to have a secure network.
