With Redstone 3/Windows 10 1709, a new security feature with the cumbersome name WDAG for Microsoft Edge was introduced. Even though it has an unwieldy name, its functionality can be explained easily. The concept of VBS is extended to software containers. So it will execute exposed software such as your browser in an extra virtual OS and connect only by Remote Desktop Protocol (RDP). The first program capable of this was Microsoft Edge, but other products will follow with the next versions of Windows 10. If a Microsoft Edge instance running in such a secure container gets hacked, it does not have access to the host OS. When Microsoft Edge is displaying a intranet or trustworthy site, it will be executed in the host OS. When surfing on other sites, a new instance in the Windows OS will be executed and connected by RDP.
