When installing software on a Windows PC or server, many changes and additions are made to the registry. This article introduces how to monitor and track these changes using Process Monitor.

Process Monitor is one of Microsoft’s official external Windows packages, so there’s no worry about malware or viruses, and it provides stable operation.
You can download the executable from:
Process Monitor - Windows Sysinternals | Microsoft Docs
Simply download it normally.

After extracting what you downloaded with WinRAR or similar, install and run it.
The listed information includes various data, such as changes on the file system, network activity, process and system activity events, and all of these are monitored and output.
To filter only registry output, click the registry icon to toggle.

You can filter by process ID/PID or process name (e.g., chrome.exe)
