Windows 7 Compressed Iso 900 Mb Fixed Here

Microsoft released Windows 7 Embedded Standard, which is a modular version designed for kiosks and ATMs. You can build a sub-1GB image officially using Microsoft's own tools (ICE - Image Configuration Editor). This is the only legitimate "900 MB" Windows 7.

Achieving a 80% compression ratio is impossible with standard tools. Here is how these custom ISOs are actually built: windows 7 compressed iso 900 mb fixed
