Windows 2000 User Profile Migration with USMT

This article provides an overview of how Microsoft Windows 2000 handles user state and profile transitions using the User State Migration Tool (USMT). It outlines the architecture of the tool, its core command-line executables, the role of configuration scripts, and the step-by-step process administrators use to capture and restore user data across enterprise deployments.

The User State Migration Tool is a scriptable, command-line utility designed for large-scale enterprise deployments rather than individual consumer upgrades. In a Windows 2000 environment, USMT facilitates side-by-side computer replacements and wipe-and-reload operating system migrations by separating user settings and personal data from the operating system, allowing administrators to automate the deployment process without manual reconfiguration.

USMT operates primarily through two command-line utilities: ScanState.exe and LoadState.exe.

  • ScanState: This tool runs on the source computer to inspect the system, identify designated user accounts, and read registry entries, system settings, and local files. It packages this information into an uncompressed or compressed migration store located on a network share or an external storage directory.
  • LoadState: After Windows 2000 is installed or configured on the target system, this tool reads the migration store created by ScanState and reconstructs the user accounts, system preferences, and application settings on the new machine.

Migration rules and target components are governed by customizable rule files, primarily using the .inf format in early USMT versions. These configuration files tell the tools exactly what to preserve:

  • Operating System Settings: Desktop configurations, screen savers, taskbar preferences, mouse settings, network mapped drives, and regional options.
  • Application Settings: Configurations for supported productivity applications, including Microsoft Office, Internet Explorer favorites and proxy settings, and Outlook or Outlook Express mail profiles.
  • User Data: Common file types and folder structures, including the "My Documents" hierarchy, desktop files, and custom directory paths defined by the administrator.

To execute a migration in Windows 2000, an administrator typically maps a secure network drive accessible by both the source and target systems. The administrator executes ScanState with specific flags indicating which user accounts to migrate and which .inf files to parse. Once the capture completes and the new Windows 2000 installation is ready, LoadState is executed on the target machine with corresponding switches. USMT handles security identifiers (SIDs) and domain mappings, ensuring that permissions and local profiles map accurately to the authenticated user on the Windows 2000 system.
