appcontainer

About this tag
The appcontainer tag on WindowsForum.com covers discussions about the AppContainer security sandbox used in Microsoft Edge and other Windows applications. Topics include how AppContainers isolate processes to mitigate arbitrary code execution, the use of Code Integrity Guard and Arbitrary Code Guard within Edge's sandbox, and the Desktop Bridge for converting desktop apps to UWP with AppContainer support. A known issue where a process running at an Untrusted integrity level is incorrectly reported as an AppContainer is also documented. These threads explore the technical implementation, security benefits, and troubleshooting of AppContainer-based isolation in Windows.
