Updates through Windows Server Update services (WSUS), System Center Configuration Manager (SCCM) and Microsoft Update catalog are supported only in the Production ring to ensure package stability.
 
 2. It takes a few minutes for the plug-in to fully instantiate, and up to 30 minutes for a WSL2 instance to onboard itself. Short-lived WSL container instances might result in the WSL2 instance not showing up in the Microsoft Defender portal ([https://security.microsoft.com](https://security.microsoft.com)). Once any distribution has been running long enough (at least 30 minutes), it does show up.
 
 3. Running a custom kernel and custom kernel command line is not supported. Although the plug-in does not block running in that configuration, it does not guarantee visibility within WSL when you're running a custom kernel and custom kernel command line. We recommend to block such configurations with help of [Microsoft Intune wsl settings](/windows/wsl/intune).

 ## Software prerequisites
 
 - WSL version 2.0.7.0 or later must be running with at least one active distro.
 
-   Run `wsl --update` to make sure you are on the latest version. If `wsl -–version` shows a version older than 2.0.7.0, run `wsl -–update –pre-release` to get the latest update.

 - The Windows client device must be onboarded to Defender for Endpoint.
 
 - The Windows client device must be running Windows 10, version 2004 and later (build 19044 and later), or Windows 11 to support the WSL versions that can work with the plug-in.
