## What it is
PE Tools is a Windows GUI toolkit for researching and manipulating Portable Executable (PE) files and running processes. It bundles a PE header/section editor, hex editor, disassembler, process viewer, dumper, rebuilder, comparator, and packer sniffer.

## Use cases
- edit PE headers and sections of a Windows executable
- dump a running process from memory
- rebuild and fix a dumped PE file
- detect which packer was used on an executable
- compare two PE files side by side
- convert between virtual addresses and raw file offsets
- view entropy of executable sections
- disassemble 64-bit code in a PE file

## When to choose
- you need a free, oldschool LordPE-style PE editor on Windows
- you are unpacking or analyzing malware samples
- you need to dump and rebuild a process image
- you want signature-based packer detection and entropy analysis

## When to avoid
- you need a cross-platform or Linux-native PE analysis tool
- you want scripted/automated analysis rather than a GUI
- you need deep static analysis like decompilation
