The newly added Windows 11 has changed a lot of things regarding the look and the way our favorite operating system worked.

There are plenty of performance improvements, a completely overhauled interface, and many other new additions that you have to check out.

Thankfully, not everything is changed. Under the hood, Windows 11 is actually pretty similar to Windows 10, but with some new systems in place.

If you are looking for the serial number of your operating system or the one of your device’s motherboard, you should know that it’s pretty easy to check them.

How do I find my PC serial number on Windows 11?

1. Use the Command Prompt

  1. Go to the Search Bar, and type Command Prompt in the search box.
  2. After Command Prompt opens, type in one of the following command and press Enter: wmic bios get serialnumber wmic csproduct get identifyingnumber
  3. After entering the command, you should get a response with the exact Windows 11 serial number.
    • If you wish to find out what your PC’s model number is, type in the following command and press Enter: wmic csproduct get name

That’s it. This method is the same as the one people used in Windows 10 since the Command Prompt hasn’t changed at all. All you have to do is follow the steps above and you’re set.

We’ve also included a way to check your computer model, in case you were wondering since it’s quite useful. It can be done using the same method, but a different command.

NOTE
The serial number will only show up if the PC manufacturer saved it in your computer’s BIOS or UEFI. They don’t always do that, so you might encounter messages like To be filled by O.E.M. after typing in the commands.

2. Check your UEFI

  1. Restart your device.
  2. Depending on your PC’s manufacturer, you will be briefly asked to press a certain key during the booting process.
  3. Press that key (Usually DEL, F1, F2, and Escape) until you open the UEFI settings.
  4. Once inside the UEFI, look for text containing the Serial number, just like the one in the picture below.
  5. You might need to select the category, or you might simply find the number showcased in the main menu.

Not every manufacturer uses a similar UEFI interface, and it usually depends on which motherboard you use, so you might not see the same UI like this one.

However, all the UEFI screens should have a Serial number section, and it doesn’t depend on your Windows version.

NOTE
Note: UEFI is the new version of BIOS. Windows 11 cannot be installed on a PC with BIOS so your computer definitely needs a UEFI to run the new OS.

3. Check your PC hardware’s box

Another way to check your serial number is to simply take your motherboard‘s shipping box and search for a sticker that contains the number.

Manufacturers will always print the serial number on their boxes, together with other information such as the production batch, etc.

Keep in mind that you need to check the motherboard’s box specifically since it is the piece of hardware where the BIOS is installed, and where all the other of your PC components are connected.

If you have a laptop, you can search for a similar sticker on its sides or on the back, since they usually also come with this information.

Additionally, if you received warranty service, the company responsible for the warranty should’ve included the serial number in a mail or some form of document.
