How does this affect Windows 7 users?
Assuming your installation of Windows 7 is legitimate, you can continue using it until the computer/laptop breaks down. To quote Microsoft:
When Windows XP lost Windows Update support, software companies, including anti-malware vendors, began dropping updates for Windows XP. The same thing will happen to Windows 7 PCs. Updates will slow and eventually stop for programs you may have installed and which you may depend upon. Your programs will fall behind the current versions and your computer's security will decrease.While you could continue to use your PC running Windows 7, without continued software and security updates, it will be at greater risk for viruses and malware.
There is no longer a free upgrade path from Windows 7 to Windows 10 (that ended 3 years ago), but you can buy into Windows 10. According to Microsoft:
If your computer's hardware and drivers support Windows 10, you will be good to go forward with the new OS. However, as new motherboards are rolled out, older boards eventually stop receiving driver updates. When driver updates don't keep up with security patches, onboard adapters stop working (e.g., audio, graphics, networking).You can purchase and download Windows 10 on your device today.* Although, if your computer is more than three years old, it might be time to consider upgrading to a new device.
* You can purchase Windows 10 licenses directly from Microsoft, or from a licensed Windows computer builder/installer, or from an authorized online reseller (e.g., Newegg, Tiger Direct, Dell, HP, Microtec, etc).
