Portable RegistryViewer

Portable RegistryViewer is a tiny software application that loads and displays data in the Windows Registry. It can be handled by all user categories, since its feature set is short and intuitive.

As the name implies, the tool is portable, meaning that no installation is required. You can drop the program files in any location on the hard disk and just click the executable to run.

There is also the possibility of saving Portable RegistryViewer to a USB flash disk or other mass storage device, in order to run it on any PC with minimum effort and no prior installers.

What's more, the app does not create new entries in the Windows registry or Start menu, leaving the HDD clean after removal.

The interface is made from a normal window with a plain and simple structure, where you can point out the registry files (SYSTEM, SOFTWARE, SAM, NRUSER.DAT, SECURITY, DEFAULT, USERDIFF) with the help of the file browser. These fields can be reset.

You can explore registry directories, copy names to the Clipboard or values as text, hexadecimal or original data, as well as save the original data to file. 

Data can be viewed on the bottom half of the screen. You can use a search function for keys, value names or value data with filters (match whole term, case sensitive mode enabled), as well as change the UI language.

The app has a minimal impact on computer performance, running on low CPU and RAM. It executes a command rapidly and works smoothly, without causing the operating system to hang, crash or pop up error messages.

Portable RegistryViewer is not exactly resourceful, but it gets the job done when it comes to viewing Windows Registry information. Unfortunately, the app has not been updated for a while.
