It seems like just yesterday that Windows 7 was in our lives, but did you know that Microsoft has discontinued its support for the iconic operating system? That means you’ll no longer receive important security updates, and worse still, there’s a new vulnerability with Windows 10 you need to be mindful of that affects both the old and the new operating system. Here’s the immediate action you need to take.

The three new Windows 10 security vulnerabilities – reported to Microsoft by the United States National Intelligence Agency, NSA – affects all systems running Windows 10 (32- or 64-bit). These vulnerabilities were announced on 15 January as part of Microsoft’s usual updates.

Of the three vulnerabilities, two are critical and may allow, for example, a malicious actor to install software, modify/create user accounts or modify data on your computer, and potentially access private and sensitive personal information.

But don’t worry, as long as you act quickly you can protect yourself. We’re joining Microsoft in urging users to patch their Windows 10 systems with the following:

For Windows 7 users, the fix isn’t so simple. As we mentioned earlier, Windows 7 is now end-of-life, meaning Microsoft will no longer be supporting the operating system. That’s a big deal, especially if you’re a small business that is obligated to protect both your data and the sensitive data of your customers. If you’re a Windows 7 user, that means you’ll need to migrate to Windows 10 as soon as possible to receive security updates protecting you against these and other vulnerabilities.

Microsoft has a guide for updating to Windows 10 from Windows 7. Ensure you update promptly to protect yourself from exploits and hackers looking to compromise you and your customers.
