ChangeAlyzer is a professional easy-to-use System Monitoring Application to detect changes in the Registry andor Filesystem. It can show you which changes are made to your System when you install any Software or when you change Settings in an Application or Windows.With that knowledge it is easy to find out if a application really needs the installation process or if it just can be started when you only have the program folder.Or you can check if an installation of a software is installing extra components like DirectX Net Framework PhysX Toolbars Spyware etc.It is also easy to find out if an application does save settings or something else in the Registry. If the application saves something in the Registry you are able to take a look on which keysvalues are used and what they contain. ChangeAlyzer gives you the possibility to export the registry changes to a .reg file ready to edit and use with a doubleclick or regedit.exe.Or maybe you want to find out in which location a Software saves files (Documents Savegames Configuration files etc.) on your hard drive This is a simple task with ChangeAlyzer.Whenever you are installing Software or change settings in an application or Windows there are basically only two things that can happen:changes to your filesystem andor changes to the Windows Registry are done.ChangeAlyzer does show these changes in a detailed view.You can choose which Drives andor Folders of your filesystem and which Keys of the Registry are scanned and ChangeAlyzer creates a Snapshot of it. After you have done your installation or changed your settings ChangeAlyzer creates a second Snapshot and shows the differences to you.The result is saved so you can take a look at it at any time. It gives you a detailed sortable view of which files andor folders are added deleted or modified. The same for the Registry you can see which Keys and Values have changed.
