Advanced Registry Tracer is an utility designed for analysing the changes made to Windows Registry by making snapshots of it and keeping them in the browsable database. You can compare any two snapshots and get the list of keys/data which are new, deleted or just changed. It can do comparing not only in the entire Regisrty, but also in any key of the Registry. It is also possible to exclude any keys of the Registry from compare results. Moreover, you can create undo/redo files. To view the current state of a key, or to modify it, you can use Jump to Regedit function. Contents of any key can be exported to *.reg file.
