Active Registry Monitor (ARM) is a utility for analyzing changes made to the Windows Registry. The program allows you to take a snapshot of the current registry and save it in a browsable database. You can then compare any two snapshots and get the list of keys/data which are new, deleted or have been changed. You can exclude selected keys, create undo/redo files and more. Active Registry Monitor compares full copies of the Registry made at different times, so it only needs to be run when actually needed.
