If you still have not upgraded to Windows 10, you should think of doing it soon since their free upgrade program ends on July 29. Another great reason why you should upgrade is because of Windows 10's new security features. These enhancements offer user protection way beyond what Windows 7 or 8 offer.

One interesting technology being introduced is biometric user authentication. Dubbed Windows Hello, this new layer of security employs facial recognition, iris scanning or fingerprint authentication for user sign-ins. Newer machines with the infrared and fingerprint scanning hardware should all be compatible with Windows Hello since Microsoft built it directly into Windows 10 with a wide support for biometric devices.

Another Windows 10 security enhancement, Microsoft Passport, makes use of two-factor authentication to verify users. With this technology, users can register another supported device, such as another laptop or a Windows phone, then use it to unlock a Windows 10 machine via a PIN or gesture.

This, combined with Windows Hello's biometric user authentication, could make the archaic character password system a thing of the past.

Under the hood, Windows 10 also employs enhanced security features even on the firmware level. Digital signatures are verified on the Unified Extensible Firmware Interface (UEFI) level, even before the operating system is loaded. If the OS loader, components and driver digital signatures have been tampered, the machine will not boot. This will protect users from malware that installs stealthily in the machine's boot loader.

Microsoft also re-enabled Control Flow Guard (CFG) in Windows 10. Basically, CFG prevents hackers from hijacking an application then redirecting calls to an invalid address. This will help protect the system from exploits such as code spoofing and memory corruption exploits and even zero-day attacks.

With these Windows 10 security enhancements, it is definitely a notch above its predecessors, offering a more secure and protected system experience. But as more and more users adopt Windows 10, hackers will start focusing their resources on finding ways to exploit it by developing newer malware.
