is a similar open-source tool that provides a user-friendly interface for file system compression. It can achieve disk space savings of 40-60% on typical Windows installations while maintaining system stability.
This tool downloads an "ESD-based" ISO, which is significantly smaller (approx. 4.28GB) compared to the standard 5.5GB+ direct download ISOs. and Safe Alternatives

Modified Windows 10 ISOs are created by removing “non-essential” components, apps, and services from the original Microsoft image. According to an Internet Archive page, these are “stripped of non-essential components, apps, and services to significantly reduce its disk footprint, memory usage, and CPU overhead”.
Stripped-down operating systems are notoriously unstable. Removing background services causes frequent Blue Screens of Death (BSOD), application crashes, and hardware compatibility issues. If a required system library is missing, your favorite games or productivity software will simply refuse to launch. No Security Patches
