How to Install Microsoft.OSConfig PowerShell Module on Windows Server 2025
In this article we will discuss about OSConfig and how to install Microsoft.OSConfig PowerShell module on Windows Server 2025. Also, we will learn about the Microsoft.OSConfig PowerShell cmdlets and its usage in Windows Server 2025.
Windows Server 2025 was announced in January 2024 to enhance security, performance, and hybrid cloud capabilities. According to Microsoft, it delivers advanced security, new Azure hybrid features, a high-performance platform for existing apps and AI workloads, and a modernized Windows Server experience.
Windows Server 2025 is designed to work seamlessly with hybrid cloud environments. Features like hotpatching, enabled by Azure Arc, allow for fewer reboots and minimal disruption, enhancing operational flexibility. The inclusion of tools like DTrace for real-time system monitoring and troubleshooting, and a modernized Task Manager, makes managing your infrastructure more efficient
Azure Arc simplifies governance and management by delivering a consistent multicloud and on-premises management platform. You could also manage your entire environment together by projecting your existing non-Azure and/or on-premises resources into Azure Resource Manager.
