Defrag Tools

Welcome to the first episode of Defrag Tools where Andrew Richards and I will be walking you through the tools we use when troubleshooting Windows PC's. Each week we'll dive into the tools from SysInternals, showing you how to use them along with our best tips and tricks. In this episode we'll be showing you how to get started by creating a thumb drive that you can use to fix PC's and troubleshoot problems.

In this episode of Defrag Tools, Andrew and I walk you through Sysinternals Process Explorer. Process Explorer is a comprehensive replacement for Task Manager. It allows you to view the details of the processes running on the computer, both at a point in time and historically. The performance graphs allow you to view the CPU, I/O, Memory and GPU usage. Process Explorer can be used to find file locks, loaded DLLs, autostart locations, and many more things.

In this episode of Defrag Tools, Chad and I walk you through Sysinternals Autoruns. We also look at its predecessors: MSConfig and SysEdit. AutoRuns and MSConfig allow you to view and disable autostart entries on the computer. The autostart entries are locations in the registry and file system that can cause applications and DLLs to be automatically run at startup, login, application launch, and at many more registration points in Windows.

In this episode of Defrag Tools, Andrew and I walk you through Sysinternals RAMMap. RAMMap allows you to see how the Physical Memory (RAM) on the computer is being used. You can see how much RAM there is, for what purpose it is being used, and if there has been any memory pressure (not enough memory). We also cover a lot of Memory Management theory to understand the data in RAMMap.

In this episode of Defrag Tools, Andrew and I walk you through Sysinternals VMMap. VMMap allows you to see how the Virtual Memory of a process is being used. You can see how much is used, for what purpose it is being used, and if there has been any memory leaks. Like last week with RAMMap, we cover some Memory Management theory to understand the data in VMMap.

In this episode of Defrag Tools, Chad Beeder and Larry Larsen walk you through Task Manager and Resource Monitor. Sometimes you can't download Sysinternals or other troubleshooting tools, at these time, you can turn to these in-box applications that allow you to investigate the computer.

In this episode of Defrag Tools, Andrew Richards and Larry Larsen start walking you through the Debugging Tools for Windows (in particular WinDbg). WinDbg is a debugger that supports user mode debugging of a process, or kernel mode debugging of a computer. This first WinDbg installment configures the system to open dumps files via an adjusted Context Menu. It shows how to set WinDbg as the (AeDebug) postmortem debugger, and how to use ProcDump v5.1 to do the same but capture the process as a dump file. It then starts to explain some basic concepts of debugging: call stacks (k), registers (r) and exception context records (.ecxr). Make sure you watch Defrag Tools Episode #1 for instructions on how to get the Debugging Tools for Windows and how to set the required environment variables for symbols and source code resolution.

This was meant to be the second part of a two part special for Defrag Tools, where Raymond Chen joins Andrew Richards and Chad Beeder to celebrate the 30 years of Windows by walking around the Microsoft Archives. Unfortunately, we hit a technical issue. We didn't realize until editing that we filled the (separate) device used to record the microphones. As a result, no audio - and thus no Part 2 this week. (We cut last week's episode at the point where we started to walk around off-camera, and soon after lost audio). Stay tuned for more computer history next week. Chad takes us to the Living Computer Museum in downtown Seattle.

In this special episode of Defrag Tools, following up on our most recent expeditions through the Microsoft Archives, Chad Beeder visits the Living Computer Museum in Seattle, and takes a hands-on trip through their extensive collection of Microsoft-related artifacts, with tour guide Aaron Alcorn.

In the spirit of Star Trek crossovers, Andrew Richards and Chad Beeder pay a visit to Gov (Rhymes With Orange) Maharaj, the co-host of The Defrag Show. We talk about how each series got started, the focus of each, and how the two sometimes overlap. Gov has a wealth of knowledge, a lot of it being garnered from his role as a developer on the Windows Application and Device Compatibility Team for over 16+ years, but also by doing research for you, to answer your questions. In this episode we cover a lot of things, but of note, we talk about the version of Windows. How it is reported to applications and drivers, and the common misconception that the version number represents functionality. We've previously taped in Studio F when visiting Raymond Chen. And we've previously talked about API Contacts with Larry Osterman. As mentioned while in the kitchen, Bill Gates made a Coke (Coca-Cola) commercial years ago.
