Process Hacker – free task manager alternative

Process Hacker is a feature-packed tool for manipulating processes and services on your computer. It has more capabilities than Windows task manager. You must run it in Administrator mode if you want to use its  full feature.

Key features of Process Hacker:

  •  A simple, customizable tree view with highlighting showing you the processes running on your computer.
  •  Detailed system statistics with graphs.
  •  Advanced features not found in other programs, such as detaching from debuggers, viewing GDI handles, viewing heaps, injecting and unloading DLLs, and more.
  •  Powerful process termination that bypasses security software and rootkits.
  •  View, edit and control services, including those not shown by the Services console.
  •  View and close network connections.
  •  Starts up almost instantly, unlike other programs.

Compared with Process Explorer, Process Hacker:

  •  Implements all of the functionality offered by Process Explorer, plus more advanced features.
  •  Performs stack traces correctly for .NET programs, with managed symbol resolution.
  •  Allows you to see what a thread is waiting on.
  •  Has advanced string scanning capabilities, as well as regular expression filtering.
  •  Highlights both relocated and .NET DLLs.
  •  Shows symbolic access masks (e.g. Read, Write), rather than just numbers (e.g. 0x12019f).
  •  Shows names for transaction manager objects and ETW registration objects.
  •  Shows detailed token information, as well as allowing privileges to be enabled and disabled.
