PeStudio is a portable and free program which is able to examine executable files in depth. It supports both 32-bit and 64-bit EXE files.
To perform an analysis of a particular file, you can drag it from Windows Explorer into the program interface. Once loaded, it will display different bits of information such as the libraries it uses and loads, import and export functions, compatibility and more. It can also be used to grab information from VirusTotal, allowing users to quickly determine whether the file has been flagged by any antivirus applications.
For users and administrators who often have to deal with executables, PeStudio is an excellent tool which provides both details for troubleshooting but also other known information from the web.
