Microsoft has released the latest Windows 11 version 25H2 (Build 26200.5074) in the Release Preview Channel for customers who want to preview what the new OS will offer before the general, widespread release cycle later this year. Microsoft isn’t aiming for more under-the-hood changes for the 25H2 update, nor a visual makeover that prior updates were usually known for. Instead, the updates are mostly focused on security. For example, Microsoft removes some of its features with the installation, like PowerShell 2.0 and Windows Management Instrumentation command-line (WMIC). Both of these were previously depreciated, as they were vulnerable to various security exploits. Additionally, IT administrators can remove pre-installed Microsoft default apps via Group Policy/MDM CSP on Enterprise/EDU devices.Interestingly, the 25H2 update is delivered as an enablement package, or eKB, so it’s not a complete OS replacement but a light switch that turns on feature code already present on machines running 24H2. Microsoft stages new features inside regular cumulative updates in a disabled state. When the eKB is installed, it flips those flags, and a single restart activates the features, upgrading the device to 25H2 with minimal downtime. Because 24H2 and 25H2 share a servicing branch, they utilize the same codebase and servicing pipeline, which provides annual feature updates with the same efficiency and reliability as monthly updates. That helps reduce package size and installation time, making the transition from 24H2 to 25H2 about as easy as rebooting. The process also resets support timelines for affected editions, for example, Enterprise and Education move to a 36-month cycle, while Pro editions follow a 24-month cycle. This keeps feature rollouts controlled and reversible until the eKB enables them.
