Created by Daniel Pistelli, Explorer Suite is a free suite of tools including a process viewer and a PE editor called CFF Explorer.

The PE editor has full support for PE32/64. Special fields description and modification (.NET supported), utilities, rebuilder, hex editor, import adder, signature scanner, signature manager, extension support etc. First PE editor with support for .NET internal structures.

Resource Editor (Windows Vista icons supported) capable of handling .NET manifest resources (who are dumpable as well). The suite is available for x86, x64 and Itanium.

The process viewer makes it possible to view information about your processes and modules. The version information for each PE makes it very easy to identify files. Also, you can dump PEs or memory regions. You can also choose to open a loaded PE with the CFF Explorer. If you're on x64 or Itanium you cannot run a 32bit version of this tool: you have to install the proper version for your processor.

Explorer Suite has been designed to make PE editing as easy as possible without losing sight on the portable executable's internal structure.This application includes a series of tools which might help not only reverse engineers but also programmers. It offers a multi-file environment and a switchable interface.

Also, it's the first PE editor with full support for the .NET file format. With this tool you can easily edit metadata's fields and flags. If you're programming something that has to do with .NET metadata, you will need this tool. The resource viewer supports .NET image formats like icons, bitmaps, pngs. You'll be able to analyze .NET files without having to install the .NET framework, this tool has its own functions to access the .NET format.
