It’s only arguably useful in an air-gapped retro PC lab for testing old software — and even then, only if you accept the malware risk.
Better legitimate alternatives for low-end PCs:

Windows 10 MiniOS v2017.09 is a modified, unofficial version of the Windows 10 operating system designed to be highly lightweight and fast, particularly on low-resource or older computers. Developed by Daniel Rodríguez (commonly known as Doofy), this version is part of a long-running series of "MiniOS" builds that strip away unnecessary background services and bloatware to maximize system performance. Overview and Purpose
MiniOS versions are "unattended" installations, meaning they are pre-configured to require minimal user input during setup. The primary goal of the v2017.09 release was to provide a stable, streamlined experience for users with older hardware, such as Intel Celeron or early Core i3 processors, which often struggle with the heavy resource demands of official Windows 10 releases. Key Features and Modifications windows 10 minios v2017.09
Reduced Footprint: The OS is significantly smaller than official versions, often fitting on smaller storage drives and using less RAM (e.g., running efficiently on systems with as little as 2GB of RAM).
Bloatware Removal: Non-essential Microsoft applications, telemetry services, and background processes are removed to free up CPU cycles.
Performance Optimization: Includes various registry tweaks and system modifications to speed up boot times and general interface responsiveness.
Simplified Interface: Many builds feature a cleaner UI or integrated tools for easier system management, such as the Doofy Projects Extended Menu which provides quick access to administrative and diagnostic tools. Important Considerations Do not use for any daily-driver, production, or
Security Risks: As an unofficial, modified version, MiniOS does not come from Microsoft. Users should be aware that security patches may not be delivered through standard Windows Update channels, and modified ISOs can pose risks if obtained from untrusted sources.
Support Status: Windows 10 itself reached its official end of support on October 14, 2025. While versions like LTSC have extended support until 2026 or 2029, modified builds like MiniOS v2017.09 are typically used as "as-is" solutions for legacy hardware. Windows 10 support has ended on October 14, 2025

Based on: Windows 10 (Version 1703 “Creators Update” / Build 15063)
The release date of v2017.09 is significant. In 2017, Windows 10 was becoming notoriously heavy due to the Anniversary and Creators updates. Many users with 4-year-old PCs at the time felt their computers slowing down. MiniOS v2017.09 was a response to that performance drop, offering a way to stay on a modern OS (supporting modern browsers and software) without the lag. If you do choose to run MiniOS, never
The version tag "v2017.09" is not arbitrary. In the modding community, builds from late 2017 are considered the "sweet spot" for performance and compatibility. Here’s why:
