Serial Number Of My Computer

How to download endnote x7

Nov 9, 2017 - This wikiHow teaches you how to find the serial number for your PC desktop or laptop using the Windows command prompt. If you don’t see your PC’s serial number, blame your PC’s manufacturer. The number will only appear here if the PC manufacturer saved it to your computer’s BIOS or UEFI firmware. PC manufacturers don’t always fill in the number properly.


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.

To Find Serial Number of PC on PC

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.
  • 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.
  • If you purchased the PC online or in a store, the serial number may be printed on the physical or email receipt.


That's it,
