Process Hacker is a feature-packed tool for manipulating processes and services on your computer. It can show you the threads (with symbols), modules, memory regions, handles and token of processes. It has detailed graphs that show CPU usage, memory usage and I/O activity. It can even change the DEP status of some processes and protect/unprotect them!

It can read/write memory using a built-in hex editor and search through memory. It has a powerful run-as tool that can run programs as almost any user, including SYSTEM, LOCAL SERVICE and NETWORK SERVICE. Finally, its kernel-mode driver enables Process Hacker to show information for any process, even if it is protected by a rootkit
