Windows diagnostics is not only something that IT analysts should worry about. Anyone with a computer should be comfortable using Windows diagnostic tools to troubleshoot basic problems.
Believe it or not, you can fix most problems yourself if you have the right tools and know how to use them.
You don’t need sophisticated tools or deep computer knowledge to diagnose Windows problems. With the right tools, any computer owner can narrow down the problems they may face.
Below are 15 of the most effective Windows diagnostics you can use to determine what may be causing problems on your Windows PC.
The first tool is one of those diagnostic applications that you don’t even know about until you use it. Most computer experts will advise you to use the Processes tab in Task Manager to see which applications might be consuming all of your CPU time.
The problem with the task manager is that it only shows top-level processes. On the other hand, Process Explorer uses a tree structure to show you not only the top-level processes, but also the child processes associated with that application.
This tool is a favorite of programmers who want to make sure that there are no memory leaks or CPU problems in their application processes.
Process Explorer also includes all of the following diagnostic features:
- Real-time charts of CPU, memory, I / O, and GPU.
- Color coding to see the most active processes.
- Get detailed information about processes such as memory, priority, handles, and more.
- Adjust the CPU load and process priority.
Download Process Explorer
When you are working with remote support and need processor information, CPUID is a powerful tool for viewing all the information you need about your processor. It can also help gather GPU or memory card information if you want to upgrade your system and find the perfect match.
It is free to download and use, and it works on both 32-bit and 64-bit systems. The amount of information about your processor and other system information is impressive.
- Processor brand and all specifications

System Explorer is an impressive tool that gives you more information about the overall performance of your system than most of the other tools available.
In addition to running processes, it includes real-time graphs, all active Internet connections, and a history of process activity.
System Explorer features include:
- A tree breakdown of all active processes.
- Built-in tool to perform file security checks on active processes.

- All running processes using your computer’s Internet connection
- Historical list of processor activities
Right in Windows 10, there is one useful diagnostic tool that you can use without installation. This is called a reliability monitor.
To open it, click Start and type reliability. Select View Reliability History.
The reliability history graph shows where errors occurred on your Windows system. These are the same errors that you can see in the Windows event logs, but they are presented graphically where errors are easy to spot.
How to use the Reliability Monitor:
- Click any red X to see more information about these errors in the lower pane.
- Click any yellow! for more information on these warnings.
- Use the Technical Viewer to view more detailed warning or error information.
You don’t have to worry about all the errors and warnings. Most Windows systems experience random errors. But if you see recurring critical errors over a long period of time, you may have identified an issue that is affecting your system’s performance.
This is a free app that you can install from the Microsoft Store. It is a powerful tool for quickly analyzing all wireless networks wherever you are.
