Other browsers offer 'sandboxes' too, but Microsoft says that Application Guard is unique because there's a hardware container that makes it impossible for malware and other exploits to seep through. The virtual PC created by Application Guard would keep the Edge browser separate from storage, other apps and the Windows 10 kernel. The whole thing is possible due to the Virtualization Based Security (VBS) made possible by Windows 10. To enable this, you need to use the 'Turn Windows features on or off' dialog, and then mark the checkbox for 'Windows Defender Application Guard.' Now when you open Microsoft Edge and click on the menu, you'll see the option for a 'New Application Guard window.' Click it, and a new special isolated browser window will appear. This Application Guard essentially encases your browser in a virtual machine, so that if your browser ever gets attacked by malware, it won't affect the rest of your PC. That's because it includes the Windows Defender Application Guard for Microsoft Edge, which was announced last September but is finally available for testing today. If the idea of a more secure Windows browser appeals to you - and why wouldn't it - then you might want to have a peek at the latest Windows 10 Insider Preview Build.
