Have you ever needed to know your computer's CPU or memory details, serial or model number, or installed software versions, but weren't sure where to look? With just a bit of simple code in Excel, you can extract a whole library of your Windows PC information.
How To Get Cpu Serial Number In Vba
However, at the end the result is always that it is only a solution for software which is sold with the Mother Board and those CPU's or Motherboard has somewhere a serialnumber which is not only available by reading with eyes.
AndyNakamura Thanks for your suggestion but i need that code which returns the serial number of the cpu or mother board serial number so that i put a condition if that serial number matches with that number than the program should work otherwise No.
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load 'Label1.Text = cpuid() Dim oMother As Object = Nothing Dim sMBserial As String = Nothing Dim oWMG As Object = GetObject("WinMgmts:") oMother = oWMG.InstancesOf("Win32_BaseBoard") For Each obj As Object In oMother sMBserial += obj.SerialNumber 'if you have more than one motherboard separate with comma 'it could happen :p If oMother.count > 1 Then sMBserial += "," Next MsgBox(sMBserial) End Sub
The WMI Information Retriever VBScript code example on the TechNet Gallery uses the Win32_ComputerSystemProcessor class to retrieve processor information from a number of remote computers.
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, including Win32_ComputerSystemProcessor, to display information about a local or remote system.
The Multithreaded System Asset Gathering with Powershell PowerShell example on TechNet gallery uses a number of classes, including Win32_ComputerSystemProcessor, to retrieve data from a system.
You need to be aware of the brand (manufacturer) and type (the product) of motherboard to check its supported components In addition, knowing the motherboard version number is also beneficial to finding the BIOS firmware updates from the sites that manufacturer supports. In this moment, the question what motherboard do I have may occur to you.
As described above, to know what motherboard model and serial number you have is very important. Hence, this part will talk about some solutions to find out motherboard model and serial number. You can pick one to check the information freely.
Motherboard model and serial number details can also be found in Windows system information. However, this way sometimes cannot work. If your motherboard is compatible, this method may be the easiest way to check your PC motherboard model and serial number.
In this simple article, I am going to show how you can protect your software from unauthorized copying by creating a serial number/activation key pair based on the physical address (MAC) of the network adapter on the client's machine.
The first step is to get the MAC address of the client's machine. This could be achieved by using the ManagementClass class located in the System.Management assembly. We have to add a reference to that assembly to our project, and import it into SecurityManager.vb, which will be the class in which we place the GetSerial() and CheckKey() functions. These two functions will be responsible for generating the serial number from the MAC address and checking whether the key entered by the user is valid. As a first step, we define the GetSerial() function as follows:
The second step is to create the key generator which will generate the activation key from a given serial number. This generator will be placed in a class called KeyGenerator. This class will contain a function which will apply a simple mathematical function on the serial number to get the activation key. In this case, I will use the function f(x) = x2 + 53/x + 113 * (x/4).
When checking warranty coverage, processing a warranty ticket, or working with Intel Customer Service, you may be asked to provide some identification numbers for your Intel NUC device. Use the instructions below to locate these numbers.
Hey, Scripting Guy! I need to perform an audit of computers on our network. Specifically, I am tasked with obtaining CPU information. I need the processor speed, number of cores, and number of logical processors. I feel like I should be able to use Windows PowerShell to do this, but I am not certain. Can you help?
For example when they read the HDD they get the volume ID. This number is indeed unique but it changes every time the user formats the drive to reinstall its operating system. We also offer a function to read this number. However, we offer the real deal: a function that reads the device ID written by manufacturer in hard drive's IDE chip. This number is absolutely unique on the planet (no other hard drive has this ID) and it is 100% unchangeable.
The same for CPU. They offer a function to read the unique serial number of the CPU. While this worked perfectly with single core CPUs, none of the libraries we have tested works properly with multi core CPUs. This is because the application can have access only to the core in which it currently runs. Unfortunately, Windows can start the application in any core, therefore you will probably see four different ID's for a quad-core CPU. Our library is the only one that works properly and extracts the correct CPU ID number. Note:
Other DLLs does not allow you low level access to the functions that extract the hardware identification numbers (maybe they try to hide that their library don't extract the true serial numbers). Instead the offer you access to a single function that extracts some the numbers hashes (MD5) these numbers and finally returns to you the hash. Our DLL gives you access to all its inner working! You can decide which hardware to read and which not and to implement the protection system exactly the way you want/need!
Do you expect this number to be changed if the install is cloned with ghost or something else? Can you depend on cloned systems always being sysprep'd following Microsoft's recommendations? The SID should be fine, if you can be sure your installs are never cloned.
Why don't you simply generate your own number the first time you run the tool and save it in the LOCAL_MACHINE registry hive? Perhaps even use an RFC4122 Type 1 number and which should include the hardware address for one of the network interfaces. That way you can check to see if the UUID still belongs to that system by comparing the UUID against the present network adapters.
You want to use the Windows Product ID. This is a unique number generated (hashed) partially from the product key installed, and partially from the hardware configuration, including processor serial number and MAC address from the first NIC. You can read about it on this (somewhat dated, but still valid) TechNet article. The product ID can be found on the System Information screen, or programatically through several methods.
After reading several posts, including those on this website, I conclude that there is no easy way to find a globally unique identifier of a Windows installation. That is too bad. Like the hardware, the software should also have its own serial number. Oh well! So this is my workaround: Instead of finding one single globally unique identifier, I have created a sylized statement, which is inspired on the way in which Microsoft names network drives on Windows and the way it names shared folders in Virtual PC: "[WINDOWS PRODUCT ID (as variable)] Installed on [COMPUTER SERIAL NUMBER (as variable)]." Although a Windows production identification number is unique only insofar as the corresponding product key is, it is, nevertheless, liable to be the same across several installations, especially on mass-produced computers containing factory-installed Windows, but a serial number is unique and is different from one machine to another. The above-mentioned formula is all I need for my purposes; I do not need the SID (I presume that it signifies Security Identifier) or something else more complex, because the combination of both variables references exactly the Windows installation that I need to identify, whereas each individual variable is, on its own, of no use to me. Specifically and firstly, the Windows product identification is identical on computers made by the same manufacturer and found in the same product line and that serves me no purpose, since I own several identical machines. Secondly, the serial number is not uniquely identifying enough, since I do have several Windows installations on one computer that a computer serial number does not address. I therefore suggest my method.
Also, and before you inquire about it: I chose not to base my method on the computer name. The information is user-based and therefore needs to be inventoried. However, the Windows product identification and the computer serial number are already identified, inventoried and invariably connected to two specific products, thereby eliminating the need to inventory them again. I would neither elect to identify a Windows installation with a unique identifier of hard drives, since I am able and quite apt to switch them around from one machine to another, especially when drive capacities are in a state of constant flux. By the same token, I would much less use the identifying nomenclature of either the central processing unit or the motherboard, as has been heretofore suggested in a previous reply by Shoeless. Finally, I also reject the most obvious option of identifying a Windows installation (although it has not been mentionned by anybody else from what I can see): using the product key. Although it is unique, it is only a license to install a certain version of Windows; it is not actually connected to a particular Windows installation and it does not distinguish it as being installed on a particular machine, even though the license was granted by virtue of the purchase a given computer. 2ff7e9595c
