 ## What is Application Guard and how does it work?
 
-Designed for Windows 10 and Microsoft Edge, Application Guard helps to isolate enterprise-defined untrusted sites, protecting your company while your employees browse the Internet. As an enterprise administrator, you define what is among trusted web sites, cloud resources, and internal networks. Everything not on your list is considered untrusted.
+For Microsoft Edge, Application Guard helps to isolate enterprise-defined untrusted sites, protecting your company while your employees browse the Internet. As an enterprise administrator, you define what is among trusted web sites, cloud resources, and internal networks. Everything not on your list is considered untrusted. If an employee goes to an untrusted site through either Microsoft Edge or Internet Explorer, Microsoft Edge opens the site in an isolated Hyper-V-enabled container.

+For Microsoft Office, Application Guard helps prevents untrusted Word, PowerPoint and Excel files from accessing trusted resources. Application Guard opens untrusted files in an isolated Hyper-V-enabled container. The isolated Hyper-V container is separate from the host operating system. This container isolation means that if the untrusted site or file turns out to be malicious, the host device is protected, and the attacker can't get to your enterprise data. For example, this approach makes the isolated container anonymous, so an attacker can't get to your employee's enterprise credentials.
