Winternals Software LP was founded by Bryce Cogswell and Mark Russinovich, who sparked the 2005 Sony BMG CD copy protection scandal in an October 2005 posting to the Sysinternals blog. The company also sold data recovery utilities and professional editions of their freeware tools. The software can now be found at Microsoft. The website featured several freeware tools to administer and monitor computers running Microsoft Windows. Microsoft acquired Winternals and its assets on July 18, 2006. It was started by software developers Bryce Cogswell and Mark Russinovich. Originally, the Sysinternals website (formerly known as ntinternals) was created in 1996 and was operated by the company Winternals Software LP, which was located in Austin, Texas. The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.Ībout Sysinternals Windows Sysinternals is a part of the Microsoft TechNet website which offers technical resources and utilities to manage, diagnose, troubleshoot, and monitor a Microsoft Windows environment. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. The Process Explorer display consists of two sub-windows. Process Explorer shows you information about which handles and DLLs processes have opened or loaded. This will track any newly created process on the system, meaning that if you launch an EXE installer and it installs an MSI, it will first need to create the MSI operation which will handle the Windows Installer execution. Introduction Ever wondered which program has a particular file or directory open? Now you can find out. Under the drop down menu, hover the Filter > Filter, go to Display entries matching this condition and select Operation is Process Create. We already covered this scenario in the MSI Packaging ebook - Helpful tools chapter, but let’s go quickly through the steps: You can filter anything from Architecture, Authentication ID, Category, Command Line, Company, Completion time, Date & Time to Version.Īnother example where filtering is important is when we want to find out if a particular EXE contains an MSI that is extracted and executed during the installation. By filtering operations, you can easily detect your issues on your system/application. Cool right?įiltering operations is one of the most important and powerful aspects of Procmon. This will ensure that only the Explorer.exe will appear in the capture, and with the registry operations filter, you will now see only what Explorer.exe operations are happening in the registry. Go to Include and click on the “Add” button.In this window, we can configure to display the entities as follows: In the main Process Monitor window, we see a list of all system operations along with their exact time, process name, ID, and the result of every operation: It is particularly helpful when you need to track which application or process accesses a file or a registry key. You can use Process Monitor to track system and application activity and troubleshoot some product issues. A long list of improvements are also added, including process monitoring, monitoring of files loaded into system memory, improved filters, process activity details, and more. Process Monitor is a Windows system monitoring tool that shows files, accessed registry keys, and active processes. We will discuss its prerequisites and share how you can get started with it. We mentioned Process Monitor in our MSI Packaging Training free e-book but this time around, we want to explore it further. Process Monitor is probably one of the most used tools by IT Pros to debug applications and check installations. Getting started with Procmon: The Beginner’s Guide to Monitoring Windows Systems
