RegMerge

With RegMerge, compare registry backups to spot variations and merge selected entries efficiently into your Windows registry. This alpha application helps streamline registry edits by identifying differences and enabling controlled integration. Note that as an early alpha, parsing errors are possible—meticulously examine the DIFF before importing and after, and reload .REG files to ensure accurate import. RegMerge tries to create REG undo files, but manually setting up a System Restore Point prior to registry changes is recommended for precaution while the tool is in alpha state.
