What you can learn from systeminfo.exe?

The tool “systeminfo.exe” has been available since Windows 2003, but only a few Windows admins seem to know it. You can get so much valuable information from it, therefore I write this blog.

You don’t need administrative rights to run it, it can be executed in a command-prompt or PowerShell or even from within the SAP system via transaction SE38 → RSBDCOS0 (the build-in “command-shell”).

Let’s take a closer look:

Host Name: WSI6601
OS Name: Microsoft Windows Server 2016 Standard
OS Version: 10.0.14393 N/A Build 14393
OS Manufacturer: Microsoft Corporation

Here, we see the Windows hostname and the Windows OS version, with or without installed Service Pack and the “Build” version number, which becomes more and more important, because Microsoft doesn’t ship any Service Packs anymore.

OS Configuration: Member Server

This information means: This host is a member of a Windows domain (Active Directory).

OS Build Type: Multiprocessor Free
Registered Owner: Windows User
Registered Organization:
Product ID: 00377-60000-00000-AA742

no important information

Original Install Date: 6/19/2017, 9:08:01 PM
System Boot Time: 6/20/2017, 8:22:37 AM

Nice! We see, when the OS was originally installed and when it was booted the last time.

System Manufacturer: IBM
System Model: System x3950 X5 -[7143H2G]-
System Type: x64-based PC

Keep an eye on this one here! If you’re running Windows on an hypervisor (like VMware, Hyper-V, KVM, XEN, etc.) you find it here. If you see the typical, well-known vendors like IBM, HP, Fujitsu, Dell, etc., then Windows is running on physcial hardware.

Nice! On physical hardware, you get details about the used firmware version and the date here.

Windows Directory: C:\Windows
System Directory: C:\Windows\system32

This should be default.

Boot Device: \Device\HarddiskVolume2
System Locale: en-us;English (United States)
Input Locale: en-us;English (United States)

Here, you should find the System Locale “en-us”, nothing else. The Input Locale can be anything.

This is very nice information about the current (!) memory usage. Based on my experience, the information display here is always correct. A low usage of physical memory doesn’t mean anything bad. But a low amount of virtual memory should alarm you!

Page File Location(s): C:\pagefile.sys

This is the name of the Windows Domain (AD) where this member server is joined to.

The current Domain Controller, where this member server is connected to.
