Microsoft has rolled out a fresh batch of updates for some of its most useful Sysinternals utilities, giving Windows administrators, developers, IT professionals, and power users several reasons to check for the latest versions.
The August 12 update includes NotMyFault, RDCMan, ZoomIt, CoreInfo, Process Explorer, Process Monitor, and PsPing, with several of these tools receiving notable version updates. Microsoft has also updated the broader Sysinternals Suite to version 2026.8.
For anyone who regularly troubleshoots Windows systems, monitors processes, investigates network performance, or manages remote desktops, these utilities remain some of the most powerful tools Microsoft provides.
What’s New in the Latest Sysinternals Updates?
Microsoft’s latest update covers seven well-known utilities:
- NotMyFault v4.6 — used to intentionally crash, hang, or create kernel memory leaks on Windows systems.
- RDCMan v3.20 — helps manage multiple Remote Desktop connections.
- ZoomIt v12.2 — provides screen zooming and drawing tools for presentations and demonstrations.
- CoreInfo v4.02 — displays detailed processor topology and cache information.
- Process Explorer v17.13 — provides deep visibility into running processes, DLLs, handles, and other system objects.
- Process Monitor v4.05 — monitors file system, Registry, process, thread, and DLL activity in real time.
- PsPing v2.13 — measures network performance.
Process Explorer and Process Monitor Remain Essential
Among the updated tools, Process Explorer and Process Monitor are arguably the most useful for everyday Windows troubleshooting.
Process Explorer gives users a much deeper look at what’s happening inside Windows than Task Manager. It can show which files and Registry keys processes have open, which DLLs they have loaded, and even which account owns a process. The latest release is version 17.13.
Process Monitor takes things even further when you’re trying to track down a problem. It provides real-time monitoring of file system, Registry, process, thread, and DLL activity, making it particularly useful for investigating application failures, permission problems, unexpected system activity, and other difficult-to-diagnose issues.
The latest Process Monitor release is version 4.05.
CoreInfo Gets a New Version
CoreInfo is another interesting update, particularly for users who want to understand exactly how their CPU is configured.
The command-line utility can show the relationship between logical processors, physical processors, NUMA nodes, sockets, and CPU caches.
Microsoft has updated CoreInfo to version 4.02.
That’s particularly useful when you’re troubleshooting performance issues on modern systems with complex CPU architectures.
RDCMan Makes Remote Desktop Management Easier
Remote Desktop Connection Manager, better known as RDCMan, remains a handy utility for anyone who needs to connect to and manage multiple remote Windows machines.
The latest version is RDCMan 3.20, giving administrators another reason to update their existing Sysinternals toolkit.
For people managing several servers or PCs, having multiple Remote Desktop sessions organized in one interface can be considerably more convenient than juggling individual Remote Desktop windows.
ZoomIt Gets Updated for Presentations
ZoomIt isn’t a traditional troubleshooting utility, but it has become a favorite among presenters, educators, developers, and Windows enthusiasts.
It provides tools for zooming into the screen, drawing annotations, and highlighting content during presentations or demonstrations.
Microsoft has released ZoomIt 12.2 as part of this update.
NotMyFault Is Definitely Not for Casual Use
Then there’s NotMyFault — a tool with a name that tells you exactly what it does.
Microsoft describes NotMyFault as a utility capable of crashing, hanging, and causing kernel memory leaks on Windows. The latest release is version 4.6.
It’s primarily intended for testing, debugging, and demonstrations rather than something you would normally run on a production PC.
In other words: don’t experiment with it on a machine where you have unsaved work.
PsPing Gets a Network Performance Update
The final tool in this batch is PsPing, Microsoft’s command-line network performance utility.
PsPing can be used to measure network performance, making it useful when investigating latency and connectivity between systems.
The latest release is PsPing 2.13.
All Seven Tools Are Part of the Sysinternals Suite
You don’t necessarily need to download each utility individually.
Microsoft maintains the Sysinternals Suite, which bundles the company’s troubleshooting utilities into a single download. The suite includes these seven tools alongside utilities such as Autoruns, ProcDump, RAMMap, TCPView, Sysmon, PsExec, and many others.
Microsoft also offers the Sysinternals Suite through the Microsoft Store. The current Store release is version 2026.8, dated August 12, 2026.
The Store version is particularly convenient because the tools are installed as an MSIX bundle, while graphical utilities such as Process Explorer can appear directly in the Windows Start menu.
Should You Update?
If you already use Sysinternals tools, yes — updating is recommended.
The August update refreshes several utilities that remain invaluable for Windows troubleshooting and administration. Even if you only occasionally use Process Explorer, Process Monitor, or PsPing, having the latest versions available can save a lot of time when something eventually goes wrong.
You can get the latest utilities from Microsoft’s official Sysinternals Utilities page or install the complete Sysinternals Suite.
The Bottom Line
Microsoft may not make a big splash every time it updates Sysinternals, but these tools continue to be a must-have toolkit for serious Windows users.
From digging into mysterious processes with Process Explorer to tracking system activity with Process Monitor, checking CPU topology with CoreInfo, testing network performance with PsPing, or managing remote machines with RDCMan, the latest releases keep one of Windows’ best troubleshooting tool collections up to date.
