I wrote about the previous release here. Here's what's new in 9.0:

  • System information dialog has per-CPU graph option with hyperthreaded and NUMA processor information
  • A Users menu duplicates the functionality of Task Manager's Users tab, showing Terminal Services session information and supporting logoff, disconnect, and sending messages
  • On XP SP2 and higher the TCP/IP tab displays the thread stack at the time an endpoint was opened
  • The tray icon context menu includes the shutdown menu
  • Search engine option to use Google or MSN Search
  • Object address column is available for the handle view
  • Image signatures can be checked on-demand in the process properties dialog
  • Process explorer is digitally signed with Sysinternals' Verisign Class 3 signing certificate
  • Mark Russinovich

    The author, Mark Russinovich, along with David Solomon also recently released the latest edition of their Windows Internals book: Windows Internals, Fourth Edition.
