Sometimes when you have some inherited Windows / Linux OS servers or Desktops, it is useful to be aware what is the Operating System install date. Usually the install date of the OS is closely to the date of purchase of the system this is especially true for Windows but not necessery true for Liunx based installs.

Knowing the install date is useful especially if you're not sure how outdated is a certain operating system. Knowing how long ago a current installation was performed could give you some hints on whether to create a re-install plans in order to keep system security up2date and could give you an idea whether the system is prone to some common errors of the time of installation or security flaws.


1. Check out how old is Windows install?

Finding out the age of WIndows installation can be performed across almost all NT 4.0 based Windowses and onwards, getting Winblows install date is obtained same way on both Windows XP / Vista/  7  and 8.

Besides many useful things such as detailed information about the configuration of your PC / notebook systeminfo could also provide you with install date, to do so just run from command line (cmd.exe).

C:\Users\hipo> systeminfo | find /i "install date"
Original Install Date:     09/18/13, 15:23:18 PM


If you need to get the initial Windows system install date however it might be much better to use WMIC command to get the info:



C:\Users\hipo>WMIC OS GET installdate

The only downside ofusing WMIC as you can see is it provides the Windows OS install date in a raw unparsed format, but for scripters that's great.

2. Check WIndows Installed and Uinstalled software and uptime from command line

One common other thing next to Windows install date is what is the Windows uptime, the easiest way to get that is to run Task Manager in command line run taskmgr


For those who want to get the uptime from windows command line for scripting purposes, this can be done again with systeminfo cmd, i.e.:


C:\> systeminfo | find "System Boot Time:"
System Boot Time:          03/29/16, 08:48:59 AM


Other helpful Windows command liners you might want to find out about is getting all the Uninstalled and Installed programs from command line this again is done with WMIC


C:\> wmic /OUTPUT:my_software.txt product get name



Alternative way to get a full list of installed software on Windows OS is to use Microsoft/SysInternals psinfo command:


C:\> psinfo -s > software.txt
C:\> psinfo -s -c > software.csv

If you need to get a complete list of Uinstalled Software using command line (e.g. for batch scripting) purposes, you can query that from Windows registry, like so:


C:\>reg query HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall

Command Output will be something like on below shot:


Well that's all folks 🙂


Windows: command to show CPU info, PC Motherboard serial number and BIOS details

Wednesday, March 2nd, 2016

Reading Time: 3minutes


Getting CPU information, RAM info and other various hardware specifics on Windows from the GUI interface is pretty trivial from Computer -> Properties
even more specifics could be obtained using third party Windows software such as CPU-Z

Perhaps there are plenty of many other ones to get and log info about hardware on PC or notebook system, but for Windwos sysadmins especially ones who are too much in love with command prompt way of behaving and ones who needs to automatizate server deployment processes with BATCH (.BAT)  scripts getting quickly info about hardware on freshly installed remote host Win serverwith no any additional hardware info tools, you'll be happy to know there are command line tools you can use to get extra hardware informationon Windows PC / server:

The most popular tool available to present you with some basic hardware info is of course systeminfo


C:\> systeminfo

                           [03]: KB2918614
                           [04]: KB2919355

Now though systeminfo's hardware details and installed Windows KBXXXXX OS Hotfix patches are getting lists the command does not provide you with info about  system’s BIOS, thus to get this info you'll have to use also wmic (Windows Management Instrumentation Command).


So What Is WMIC?

WMIC extends WMI for operation from several command-line interfaces and through batch scripts. Before WMIC, you used WMI-based applications (such as SMS), the WMI Scripting API, or tools such as CIM Studio to manage WMI-enabled computers. Without a firm grasp on a programming language such as C++ or a scripting language such as VBScript and a basic understanding of the WMI namespace, do-it-yourself systems management with WMI was difficult. WMIC changes this situation by giving you a powerful, user-friendly interface to the WMI namespace.

WMIC is more intuitive than WMI, in large part because of aliases. Aliases take simple commands that you enter at the command line, then act upon the WMI namespace in a predefined way, such as constructing a complex WMI Query Language (WQL) command from a simple WMIC alias Get command. Thus, aliases act as friendly syntax intermediaries between you and the namespace. For example, when you run a simple WMIC command such as

Here is how to wmic to get PC Motherboard serial numbers, CPU and BIOS details:


C:\> wmic bios get name,serialnumber,version


Above will print  name if your BIOS, current version and it’s serial number if there is any.

If you need to get more info about the specific Motherboard installed on host:


C:\> wmic csproduct get name,identifyingnumber,uuid


This command will show motherboard modification and it’s UUID

If you want to quickly get what is Windows running hardware CPU clock speed

C:\> wmic cpu get name,CurrentClockSpeed,MaxClockSpeed


Also if you have turbo boost CPUs above command will help you find what’s the Max Clock Speed your system is capable of for the current hardware configuration.

If you do have dynamic clock speed running, then add this line, will refresh and monitor the Clock speed every 1 second.

C:\> wmic cpu get name,CurrentClockSpeed,MaxClockSpeed /every:1

Actually wmic is a great tool

Check Windows load avarage command – Get CPU usage from Windows XP / 7 / 8 / 2012 server cmd prompt

If you used to be a long years Linux / UNIX sysadmin and you suddenly have to also admistrate a bunch of Windows hosts via RDP (Remote Desktop Protocol)  / Teamviewer etc. and you need to document The Load Avarage of a Windows XP / 7 / 8 servers but you're puzzled how to get an overall load avarage of Windows host via command in a UNIX way like with the good olduptime  Linux / BSD command e.g.

 ruth:$ uptime
 11:43  up 713 days 22:44,  1 user,  load average: 0.22, 0.17, 0.15

Then its time to you to get used to WMICWMIC extends WMI for operation from several command-line interfaces and through batch scripts. wmic is a wonderful command for Command addicted Linux guys and gives a lot of opportunities to query and conduct various sysadmin tasks from Windows command prompt.

To get an loadavarage with wmic use:

C:\>wmic cpu get loadpercentage



@for /f "skip=1" %p in ('wmic cpu get loadpercentage') do @echo %p%


on Windows 7 / 8 and 10 as well Windows Server 2010 and Windows Server 2012 for more precise CPU loadavarage results, you can also use:

C:\> typeperf "\processor(_total)\% processor time"
