Microsoft’s Windows Defender Application Guard has been added to the upcoming Microsoft Edge. This security feature allows you to securely browse the web without fear of becoming infected by malicious sites. Application Guard is a Windows 10 feature that enables Microsoft Edge to launch in an environment that is walled off from the rest of the operating system. With this feature added, the new Microsoft Edge continue to move further away from other Chromium-based browsers and allows it to stand out as a unique and worthy contender to Google Chrome.
