1. Overviews

Windows 11 24H2 continues to be updated by Microsoft in March 2025, bringing significant improvements in performance, features, and user experience. To upgrade or reinstall the operating system safely, downloading the original ISO file directly from Microsoft is the optimal choice. In this article, we will explore how to download the Windows 11 24H2 ISO (March 2025 update) and the key highlights of this version.

Windows 11, version 24H2 (also called Windows 11 2024 Update) is a significant feature update for the Windows 11 operating system.
This version integrates improvements, new features, and bug fixes that were released through cumulative updates of Windows 11 23H2.
The official ISO for 24H2 is provided by Microsoft (for users who want to install fresh/clean) — you can download it from Microsoft’s official website or authorized distribution channels.
For organizations or managed systems, 24H2 is supported through Windows Update for Business, WSUS, etc.
Note: At the time of writing this (2025), Microsoft has already released Windows 11 25H2, but 25H2 shares the same servicing branch with 24H2; many new features of 25H2 were already embedded in 24H2 (but disabled until activated).

2. System Requirements

To install or upgrade to Windows 11 24H2, your system must meet the following minimum requirements:

Component	Minimum Requirement
CPU Architecture	64-bit (x64) — Microsoft no longer releases 32-bit versions
TPM & Secure Boot	TPM 2.0 + Secure Boot
RAM	Minimum 4 GB
Storage	At least 64 GB free space
Display / Resolution	A monitor supporting minimum Windows 11 resolution
CPU Instruction Requirement	For systems using “unsupported hacks” to bypass TPM, 24H2 requires CPU support for SSE4.2 and POPCNT instructions

Notes:

Official ISO does not apply to 32-bit systems.
On Copilot+ PCs (computers with AI/NPU hardware), special AI-related features are enabled.

3. Highlighted New Features of Windows 11 24H2

3.1. AI & Intelligent Experience

Windows Studio Effects: improve camera and audio quality in apps like Teams, Zoom, Skype — including background blur, portrait lighting, eye contact effects, filters, etc.
Live Captions: real-time captions from system audio, supporting live translation (on supported hardware).
Auto Super Resolution: upscaling to increase game frame rates while keeping image quality relatively high — requires compatible hardware.
Windows Recall (preview): allows users to “recall” previously viewed content (documents, photos, links) and quickly retrieve them.
Click to Do (preview): an overlay interface for tasks like text summarization, transferring content, using Bing Visual Search, etc.
Image Creator & Restyle Image: automatic image generation and style adjustment features.

3.2. Connectivity, Interface & User Experience
