About:
CrystalFetch is a graphical user interface that streamlines the process of downloading Unified Update Platform (UUP) files from Microsoft's servers. It then automatically converts these files into a bootable Windows installation ISO image, eliminating the need for manual command-line steps.
Key Features:
  • Graphical interface for UUP file downloading
  • Automated conversion to ISO format
  • Supports multiple Windows editions and languages
  • Built-in checksum verification
Use Cases:
  • Creating custom Windows installation media without Media Creation Tool
  • Downloading specific Windows builds for testing or development
  • Generating ISOs for systems without direct internet access during install
Alternatives:
  • Microsoft Media Creation Tool – Official tool but less flexible for specific builds and editions
  • UUP dump scripts – Manual command-line process that CrystalFetch automates
