+##Windows Subsystem for Linux (WSL) 
+Windows Subsystem for Linux (WSL) is a feature of Windows that allows you to run a Linux environment on your Windows machine, without the need for a separate virtual machine or dual booting. WSL is designed to provide a seamless and productive experience for developers who want to use both Windows and Linux at the same time. In Ge, we added 3 networking security features and Intune/MDM integration in WSL on Windows 11 (SV2 and Ge) for Enterprises: 
+- Hyper-V Firewall: This new firewall setting is a network firewall solution that enables filtering of inbound and outbound traffic to/from WSL containers hosted by Windows.

+- DNS Tunneling: This new networking setting improves compatibility in different networking environments and makes use of virtualization features to obtain DNS information rather than a networking packet. 
+- Auto proxy: This new networking setting enforces WSL to use Windows' HTTP proxy information. Turn on when using a proxy on Windows, as it will make that proxy automatically apply to WSL distributions.
+- Intune/MDM setting in WSL: Microsoft Defender for Endpoint (MDE) now integrates with WSL, providing the ability to monitor what’s running inside of your WSL distros and report them to your online MDE dashboards.

 ## App containers
 
 In addition to Windows Sandbox for Win32 apps, Universal Windows Platform (UWP) applications run in Windows containers known as *app containers*. App containers act as process and resource isolation boundaries, but unlike Docker containers, these are special containers designed to run Windows applications.
