If you install a lot of Windows apps, and ever wanted to know, what changes has been made to your windows registry? RegFromApp is a free windows utility for Windows 2000, Windows XP, Windows Server 2003, and Windows Vista (32-bit only), that monitors the registry changes made by the application that you selected, and creates a standard RegEdit registration file (.reg) that contains all the Registry changes made by the application. You can use the generated .reg file to import these changes with RegEdit when it's needed.
RegFromApp doesn't require any installation process or additional dll files. In order to start using it, simply run the executable file - RegFromApp.exe. After running it, select the process that you want to inspect, and click Ok. After clicking Ok, each time that the selected process writes a value into the Registry, the main window of RegFromApp will display the written value in Windows .reg file format. You can copy & paste the desired values to another Registry file, or alternatively, you can save the entire Registry changes into a .reg file by using the 'Save As' option.
