How to Find Serial Number of Windows PC
Sometimes abbreviated as Serial No., SN or S/N, a serial number is a unique number assigned to the PC by the OEM (Original Equipment Manufacturer) used for identification and inventory purposes. A serial number allows the manufacturer to identify a product and get additional information about it, for replacement, or as a means of finding compatible parts.
This tutorial will show you how to find the serial number of your Windows 7, Windows 8, or Windows 10 PC.

1 Open a command prompt.
2 Copy and paste either command below into the command prompt, and press Enter.
wmic bios get serialnumber
OR
wmic csproduct get identifyingnumber
3 You will now see the serial number of your PC in the command prompt. (see screenshot below)
The serial number will only show in the command prompt if the OEM saved it to your PC's BIOS or UEFI firmware.

1 Open PowerShell.
2 Copy and paste either command below into PowerShell, and press Enter.
Get-WmiObject win32_bios | Format-List SerialNumber
OR
gwmi win32_bios | fl SerialNumber
3 You will now see the serial number of your PC in PowerShell. (see screenshot below)
The serial number will only show in PowerShell if the OEM saved it to your PC's BIOS or UEFI firmware.
If the OEM didn't, or this is a self built PC, then you may see To be filled by O.E.M in PowerShell instead.
1 Boot to your PC's BIOS or UEFI Firmware settings.
2 Look on the Main or System Information type page in BIOS/UEFI for your serial number. (see screenshots below)
The serial number will only show if the OEM saved it to your PC's BIOS or UEFI firmware.
1 Perform one of the following actions to find the serial number on your OEM PC: (see screenshot below)
- If you have a laptop, flip it over to the bottom side. On some laptops, you will see the number on a manufacturer sticker on the bottom of the laptop. On others, you’ll see the number printed directly on the metal or plastic. If your laptop has a removable battery, the serial number is sometimes on a sticker inside the battery compartment, under the battery.
- If you have a desktop, look at the back, top, side, or inside of the case for a manufacturer sticker.
If you can’t find the serial number on the PC itself, look online for instructions specific to your PC's model number. The manufacturer’s website should tell you exactly where to look.
1) If you still have the original product box, the serial number is usually printed on it. Often on the same sticker with the bar code.
2) If you purchased the PC online or in a store, the serial number may be printed on the physical or email receipt.
This option requires that you have previously signed in to the Windows 10 device with your Microsoft account.
Usually, only OEM type devices will have their serial number available with this option.
1 Go to the Devices page online for your Microsoft account, and sign in if you are not already.
2 Click/tap on the Manage or Show details link under the device you want to see its serial number. (see screenshot below)
3 Click/tap on the Info & support link at the top, and look for the Serial number (if available) under Device details. (see screenshot below)
That's it,
Shawn

Good spot. I thought it was my PC.
From the BIOS on your MB. You always have one. https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx
If you are running a VM you can change it quite easily by just typing something else in the relevant XML (note your Windows activation is based on this though so you'll definitely become deactivated). Otherwise no, it is generally read only

Note: if you have updated your BIOS since buying it, don`t be surprised the the command prompt or PowerShell commands do not work, your BIOS has been overwritten, so only the OOBE motherboard information is there.
All my HYRICAN OEM information was zapped away, and replace with MSI's basic info.

Just to be clear it is the first powershell command on option 2 that is wrong.
It says this:
Get-WmiObject win32bios | Format-List SerialNumber
It should say this (with the underscore)
Get-WmiObject win32_bios | Format-List SerialNumber
