The Windows 11 February 2026 Update is substantial in size, with extracted update packages exceeding 4GB. This increase in size is attributable to Microsoft bundling local AI models, such as Phi, within monthly security updates.

These AI models will also be part of the.msu installer, even on unsupported devices, but rest assured, Microsoft ensures that these models will not be activated on systems lacking a Neural Processing Unit (NPU) with 40+ TOPs.

What’s New in Windows 11 Build 26200.7840 (25H2) / Build 26100.7840 (24H2)?

1. Enhanced ‘Cross-Device Resume’ Feature

The ‘Resume’ feature in Windows 11 has been available for some time, but its functionality was quite limited, primarily only working with OneDrive. Following the February update, this feature has broadened its capabilities to include other applications. Now users can resume activities with apps like Spotify, Microsoft Word, PowerPoint, and even compatible web browsers upon switching devices.

For instance, if you’re listening to a song on Spotify using your Android phone and switch to your PC, a notification will appear allowing you to seamlessly continue playback. Supported devices include brands such as:

HONOR
Samsung
vivo
Xiaomi
OPPO

2. Introduction of Windows MIDI Services

Windows 11 now supports a new “MIDI engine, ” enhancing compatibility and functionality for music applications. This update allows the system to handle both MIDI 1.0 and MIDI 2.0, ensuring that older applications remain functional while embracing new standards.

3. Flexibility in Smart App Control

The new update brings enhanced control to Smart App Control (SAC), allowing users to enable or disable this feature without needing to perform a complete operating system reinstall. Previously, this was a cumbersome process that required significant time investment.

4. Wider Rollout of the New Start Menu

After rigorous testing, Microsoft is now widely distributing the revamped Start menu with this update. The new interface promotes easier navigation by reducing the number of clicks necessary to find applications.

This updated Start menu features categories for apps, but customization options remain limited. Though it covers a significant portion of the screen, there are currently no plans for resizing options.
