Jun 29, 2017  I question naming a computer after the user who's logged in. What if you reprovision the machine to someone else? Now the script has got to rename it again? What if someone just borrows it? Naw, I say name the computer after the serial number and be done with it forever. That wouldn't be ideal for our use case here.

If you ever have to pull system Serial Number for warranties, you know it can be a pain, especially if you have to drive to a location to pull it. here is a quick way to get it from the bios using WMI Calls.

3 Steps total

Step 1: Open CMD

Hit Win+ R and type in CMD. Press Enter

Step 2: Run the command

Type in 'WMIC Bios get serialnumber'

Step 3: Get results

If you have a Dell you will see the service tag for the system. if you have an HP, you will see the SN of the system.

You can incorporate WMI calls into almost any script/powershell instance for easy automation. We use this same call to name our computers during MDT imaging.

  Thanks for sharing. Good way to get the serial number when the sticker gets taken off.

  Also, you can use the following commands to get the name and model of the computer:
  WMIC ComputerSystem Get name
  WMIC ComputerSystem Get model

  That was bloody fantastic!!
  six more words to go, why do they have minimum words? it just means i have to waste my time writing rubbish that isn't relevant.

  Would anyone out there have a good script that can pull the BIOS serial number, The computer hostname, and the hard drive SN all at the same time.

  I've used
  wmic path win32_physicalmedia get serialnumber for the hard drives
  wmic bios get serialnumber for the Dell service tag
  I know the host name i'm hitting but I would love the information on the same line with the Serial Numbers.

  I'm looking for something that could combine it all in say a tab delimited text file or excel table. Digimon world dusk ds cheat codes. I'm not the best at scripting and can't find how to combine them in one fancy query.

  What would be the command to pull a BIOS serial number from a remote system?

  Amazing thank you, we just have Surface Pros at work now. The serial numbers are insanely tiny and hidden away and make my eyes bleed

  TimY - is say the easiest way would be to use psexec from sysinternals.

  There are a lot of helpful commands in wmic that can be used with WMIC. Monitor info, physical info on the memory in the board (see what is installed without opening up the case), ports, etc.

  run WMIC /? to see them

  Powershell also works great for this.

  get-wmiobject win32_computersystemproduct

  or for a remote machine
  get-wmiobject win32_computersystemproduct -computername computername

  I wrote a (very) simple PowerShell script, I've had expanded versions of it in the past (but they got lost - easy to recreate, though). It pulls information (name, OS, license, serial number, asset tag, etc. and saves it in a file %NAME%.txt as well as adds it to a text file which can be renamed to CSV and opened in Excel.

  You run it as an admin (too bad the screen is narrow, it's a lot easier to read when it's wide enough):

  $Computer_Name=(Get-WmiObject -Class Win32_ComputerSystem -Property Name).Name
  $SerNum=(Get-WmiObject win32_SystemEnclosure).serialnumber
  $Asset=(Get-WmiObject Win32_SystemEnclosure).SMBiosAssetTag
  $License=(Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey
  $vendor=(Get-WmiObject win32_ComputerSystem).Manufacturer
  $model=(Get-WmiObject win32_ComputerSystem).Model
  $Windows_Ver=(Get-WmiObject win32_OperatingSystem).caption
  $bit=(Get-WmiObject win32_OperatingSystem).OSArchitecture
  ('Computer Name: ' + $Computer_Name) Out-File $($Computer_Name + '_report.txt')
  ('Asset Tag: ' + $Asset) Add-Content $($Computer_Name + '_report.txt')
  ('Serial Number: ' + $SerNum) Add-Content $($Computer_Name + '_report.txt')
  ('Windows Version: ' + $Windows_Ver + ' ' + $bit) Add-Content $($Computer_Name + '_report.txt')
  ('Windows License: ' + $License) Add-Content $($Computer_Name + '_report.txt')
  ('Vendor: ' + $vendor) Add-Content $($Computer_Name + '_report.txt')
  ('Model: ' + $model) Add-Content $($Computer_Name + '_report.txt')
  $Computer_Name + ',' + $Asset + ',' + $SerNum + ',' + $Windows_Ver + ',' + $License + ',' + $vendor + ',' + $model Add-Content list.txt

  I use this one to get the BIOS version when checking to see if there's an update available from Dell:

  wmic bios get smbiosbiosversion

WMI tasks for computer hardware obtain information about the presence, state, or properties of hardware components. For example, you can determine whether a computer is a desktop or laptop. For other examples, see the TechNet ScriptCenter at https://www.microsoft.com/technet.

The script examples shown in this topic obtain data only from the local computer. For more information about how to use the script to obtain data from remote computers, see Connecting to WMI on a Remote Computer.

To run a script

The following procedure describes how to run a script.

1. Copy the code and save it in a file with a .vbs extension, such as filename.vbs. Ensure that your text editor does not add a .txt extension to the file.
2. Open a command prompt window and navigate to the directory where you saved the file.
3. Type cscript filename.vbs at the command prompt.
4. If you cannot access an event log, check to see if you are running from an Elevated command prompt. Some Event Log, such as the Security Event Log, may be protected by User Access Controls (UAC).

Note

By default, cscript displays the output of a script in the command prompt window. Because WMI scripts can produce large amounts of output, you might want to redirect the output to a file. Type cscript filename.vbs > outfile.txt at the command prompt to redirect the output of the filename.vbs script to outfile.txt.

The following table lists script examples that can be used to obtain various types of data from the local computer.

Examples

The following TechNet Gallery example code describes how to list the free space of all drives for several machines.

The Get-ComputerInfo - Query Computer Info From Local/Remote Computers - (WMI) PowerShell sample on TechNet Gallery uses a number of calls to hardware and software to display information about a local or remote system.

The Multithreaded System Asset Gathering with Powershell PowerShell sample on TechNetGallery gathers a plethora of useful system information via WMI and multithreading with powershell.
