Top free troubleshooting tools for Windows

These seven handy tools help you diagnose and cure a wide range of Windows ills, and they're all free for the downloading

No computer runs perfectly forever. Somewhere along the line, something will go wrong. While each successive version of Windows has been that much more reliable and self-healing, that's never been an argument to forgo a good collection of software tools.

Over the years I've accumulated a slew of third-party troubleshooting apps that have proven their value again and again, so much so that they're among the very first programs installed in any system I use. If something goes wrong -- a Blue Screen of Death, a slow-booting system, a recent program install that's made everything slower than molasses going uphill in January -- I turn to these tools to set things right. All of them are free for personal use, some are open source, and each of them deserves a place in the toolbox of the savvy Windows user.

[ There's no shortage of great free tools for Windows. See also "Top 10 Windows tools for IT pros" and "The best free open source software for Windows." ]

Sysinternals's Process Explorer
"Task Manager on steroids" -- that's how someone described Process Explorer to me when Mark Russinovich first released it many years ago. It can replace Task Manager or run side by side with it, but either way it's an absolute must-have for technically savvy users. I typically use it as the replacement for Task Manager on any PC I run; it's just too handy not to have installed.

Windows 7 Deep Dive

When you launch Process Explorer, you'll see a tree view of processes; they're nominally organized by which process spawned which, but you can click on the column headers to change the sorting as you please. The top portion of the window has four graphs: CPU usage, commit history, I/O bytes history, and physical memory history. Click on one to bring up a full-sized window view that's akin to the Performance tab in Task Manager -- but with a level of detail and insight into what programs are doing that Task Manager doesn't even come close to providing.

Double-click on the name of a process, and up pops a window with a startling amount of detail: the process's running threads (and the stack for each thread), which can be frozen or killed; its permissions; its network access; the program it was launched from; even a dump of text strings in either the on-disk program image or its copy in memory. Processes, or whole trees of them, can be killed off, frozen, resumed, or have their windows or priorities manipulated -- handy if a process window vanishes behind something else and you need to force it to the front. You can also toggle on or off a lower pane that contains detailed information about a process, find the process for a particular window by pointing to it, or search by name for any running process, handle, or DLL.

Move over, Task Manager. Process Explorer can do everything you can do, and more.

I was happy to find this line above... "a Blue Screen of Death, a slow-booting system, a recent program install that's made everything slower than molasses going uphill in January" because I have a slow-booting XP system that takes over 20 minutes to come up. The hard drive light blinks the whole time. I read the entire article above but I don't know which tool will help me diagnose and fix my problem. I've already scanned it for viruses, root kits, malware, hard drive problems and the drive has been defragmented. I've run all of the tools with System Mechanic and there are no registry problems plus it shows my system is healthy. I've been fixing computers for over 15 years and this one has me stumped. Any suggestions? Which tool above can help me? None of the copy in the article addressed slow booting PCs directly, so please let me know.

Wow, those are some neat programs. I really miss having all those things available to me to trouble shoot problems. I used to spend some real quality time running defrag and checking up on how my antivirus programs were doing and all the times I spent rummaging around getting rid of some perfectly good cookies and temporary internet files. All really good stuff. I remember those days with fondness. Really the only thing about my computers now is I just can't find any of these sorts of programs. I really need to go to a good computer shop and maybe they will be able to tell me where to find them.....

I'd really like to find some tools to help with dealing with log files - the event log of a machine, the SharePoint and IIS logs, etc. Right now, these logs are filled with information that is difficult to determine what to do wtih. Finding some tools that summarize, point out errors, lead one to solutions, etc. would be a great benefit.
