Registry Bookmarks - Version 1.0 Enables power users and developers to quickly access their favorite Registry settings. You can bookmark any key in the Registry and then access it directly from the system tray. This powerful feature allows you to create a set of Registry keys that you frequently access eliminating the need to manually open REGEDIT. The software comes with a set of predefined commonly used keys. Registry Bookmarks uses the REGEDIT tool so you don’t need to learn how to edit, delete or rename Registry keys.
