Resource Hacker

Resource Hacker (also known as ResHacker or ResHack) is a free resource extraction utility and resource compiler for Windows developed by Angus Johnson. It can be used to add, modify or replace most resources within Windows binaries including strings, images, dialogs, menus, VersionInfo and Manifest resources. Security researchers use it to analyze malware. ResHack can also create resource files (*.res) from scratch, and it provides a number of text templates to facilitate this.
