A very powerful, versatile, and customizable Win32 user mode debugger/disassembler.

PEBrowse Interactive is not a source code debugger, but operates at the Intel x86 instruction level and therefore at the lowest level where your program executes.

The debugger fully supports Microsoft .NET managed processes and seamlessly allows interop or mixed-mode debugging.

It can be set as the startup debugger using the system registry Image File Execution Options key - useful for debugging ASP.NET applications.
