Portable ERUNTgui is a free graphical user interface (GUI) designed for the legacy, command-line utility ERUNT (Emergency Recovery Utility NT). ERUNT is heavily favored by IT technicians because it creates a 100% complete backup of the Windows Registry, including the critical security hives and user permissions that standard Windows tools (like regedit exports) completely miss.
The portable version allows you to run this tool directly from a USB thumb drive without installation, making it highly versatile for multiple systems. Why Use ERUNTgui Over Regedit?
Full Security Hive Backup: Native Windows exports leave out crucial security and permissions data.
True Overwrite Restoration: Restoring via regedit merges files, leaving old, potentially corrupt registry data intact. ERUNT completely restores the clean snapshot. Step 1: Downloading Portable ERUNTgui
Because ERUNT and ERUNTgui are older utilities, you will not find them hosted on modern official product pages. Instead, secure platforms host the archive:
Download the standalone tool from verified tech repositories like Softpedia ERUNTgui or MajorGeeks.
Select the Portable / ZIP edition rather than the installer.
Extract the ZIP archive folder directly to your PC or onto a external flash drive. Step 2: Complete Registry Backup Guide
