The Microsoft Support Diagnostic Tool is a hidden tool in Windows 10. It’s not known to a lot of people, and it’s not something you really need to know until you need it. Either way, it’s good to learn about this tool, its work, and when it will come in handy.

Let’s explore the Microsoft Support Diagnostic Tool and what it does.

What is the Microsoft Support Diagnostic Tool (MSDT)?

This tool is not like other diagnostic tools. While other Windows 10 tools tend to fix and fix things, the MSDT only reports what is happening on your computer. Worse, you can’t even run it yourself – if you try, you’ll be prompted for a password that you won’t have!

The reason is that the MSDT is part of a larger support system. It is only used if you are currently talking to a Microsoft technician about an issue with your computer and the technician decides that logs of what is happening are needed.

When this happens, the technician will give you a password to enter the MSDT. The tool will then begin to track what you are doing on the computer and send data to Microsoft for diagnosis. The technician may ask you to perform specific actions or run certain tools to get a better idea of ​​what your PC is doing.

How to run the Microsoft Support Diagnostic Tool

If the technician asks you to start the MSDT, it is very simple. Tap the Start button at the bottom left, then type MSDT. Click on the entry that appears or press the Enter key.

Unfortunately, that’s as far as you can go – it’ll then ask you for a password, which you won’t have unless you’re in a conversation with a technician who has explicitly given you one. However, it’s good to know this in advance, so you’re ready when a Microsoft technician asks you to open it during technical support.

How to diagnose your own computer

If you’d rather not wait for a technician to give you a password and want to jump into diagnosing your own PC, you can. However, you will not be using the MSDT; instead, you will use the system diagnostic report.

Getting started is simple: click the Start button, then type run. Click the Run command that appears or press Enter.

Once the Run command window is open, type perfmon /report in the command line and press Enter.

A window will open and run for sixty seconds. Once done, it will give you an overview of any errors or disturbing signs you have encountered. If you’re just looking for general system errors, don’t hesitate to wait the sixty seconds.

Otherwise, if you are trying to troubleshoot something specific, perform the action during the sixty second window and see if perfmon catch the problem.

Make the diagnosis

Although it is very easy to open the MSDT, there is no reason to do so unless instructed to do so by a technician. If you really want to run diagnostics on your Windows machine, perfmon is a great way to do a quick health check.
