Integration of support for Linux environments based on the WSL2 subsystem
Microsoft has announced the integration of support for Linux environments based on the WSL2 subsystem (Windows Subsystem for Linux) into the released June consolidated update of Windows Server 2022. Initially, the WSL2 subsystem, which allows running Linux executables on Windows, was offered only in Windows versions for workstations. This became known on June 22, 2022.
To ensure the launch of Linux executables in WSL2, instead of an emulator that translated Linux system calls to Windows system calls, an environment with a full Linux kernel is provided. The kernel offered for WSL is based on the Linux 5.10 kernel release, which is expanded with WSL-specific patches that include optimizations to reduce kernel startup time, reduce memory consumption, return Windows to freed Linux memory processes, and leave the minimum required set of drivers and subsystems in the kernel.
The kernel runs in a Windows environment with the help virtual machine already involved in. Azure The WSL environment runs in a separate disk image (VHD) with an ext4 file system virtual and a network adapter. User space components are installed separately and are based on assemblies of various distributions. For example, for installation in WSL, builds are offered in the Microsoft Store directory ,/ Ubuntu Debian GNU Linux, Kali Linux,, Fedora Alpine, and. SUSE openSUSE
Additionally, we can note the corrective release of the Linux distribution CBL-Mariner 2.0.20220617 (Common Base Linux Mariner), which is developing as a universal basic platform for Linux environments used in cloud infrastructure, edge systems and various Microsoft services. The project is aimed at unifying Linux solutions used in Microsoft and simplifying the maintenance of Linux systems for various purposes in the current state. Project developments are distributed under the MIT license[1]
Block vulnerable drivers with WDAC
On March 29, 2022, it became known that Microsoft provided Windows users with the ability to block drivers with vulnerabilities using Windows Defender Application Control (WDAC) and the "blacklist" of vulnerable drivers.
This option is part of the Core Isolation security feature set for devices that use virtualization-based security. The feature works on devices running Windows 10, Windows 11, Windows Server 2016 and later with Hypervisor-Protected Code Integrity (HVCI) enabled, as well as systems running Windows 10 in S-mode.

2021: Windows Server 2022 Announcement
On March 2, 2021, the company Microsoft announced Windows Server 2022. By this time operating system , it is presented as a preliminary version (preview) and is available for download to Insider program participants Windows. Among the main features of the updated server platform, the manufacturer included:
- advanced multilayer security system. Microsoft says that the main thing in this release is the addition of kernel protection capabilities to System Guard in Windows Defender, as well as security features based on. virtualizations The company also promises to improve the speed and safety HTTPS of -connections and add enciphering SMB AES-256.
- hybrid capabilities implemented with Azure. According to the developers, Windows Server 2022 has an improved hybrid server management system, and more functions have been delegated to the cloud infrastructure. Windows Server 2022 supports Azure Arc, a suite of technologies that extends Azure management capabilities to local, multi-user environments and peripherals. Azure Arc allows customers to use a centralized, unified self-service approach to manage their Windows and Linux servers, Kubernetes clusters, and Azure data services. Integration with Storage Migration Service provides "continuous synchronization" with minimal latency between local file servers and Azure storage.
- flexible application platform. The updated OS provides tools that improve development speed and support for business-critical applications, such as SQL Server. Several improvements related to Windows containers have been added to Windows Server 2022. First of all, the size of the Windows Containers image is reduced, which leads to a reduction in boot time and increased performance.[2]
