In this article, we will learn how to check the Windows 10 CD key serial number.
Sometimes, I didn’t know the CD key on my computer, so I had a hard time when I had to install a new one. It doesn’t matter if you know because the original box is well kept, but sometimes, if you do not have a serial number when you format and reinstall Windows, you can’t get activation. If you do not know the serial number, you can check it in advance and keep it well, so that if there is a problem later, you can reinstall it to receive activation. There may be situations in which Windows suddenly crashes and you cannot find out with the method I introduced now, so it is recommended to back up the CD key in advance.
First, press Windows Key + R to open the Run window. And type cmd. 윈도우10 시리얼 확인

When you run the command, you will see a screen like the one above. Here, the red square box is the Windows 10 CD key. Since it is the serial number I am using, the number has been mosaicked.
Copy that number and keep it by e-mail or keep it on a separate external hard drive. There may be cases where the computer goes wrong after saving it on your own computer, so it is best to keep it outside.
Please note that the product key is a 25-character code. XXXXXX-XXXXX-XXXXX-XXXXX-XXXXX
When you format and reinstall Windows 10, you can either enter the product key during installation or enter it after installation.
When entering after installation, click the Start button and then click the gear-shaped settings icon.
On the Settings screen, click Update & Security.
Then click on the “Activation” menu on the left.
If you click Change Product Key on the activation screen, a pop-up window for entering the product key opens. If you enter the CD key of the number you backed up earlier here, you can get activation.
Also, depending on the product key, there are cases where the expiration date is set. This is not applicable if you purchased a genuine product for general personal use. Occasionally, if you buy cheap online or crack it, the period is often set. If you are curious about the expiration date of your product key, type slmgr -xpr at the command prompt screen. Then, the windows Scrpit Host window appears and you can use it permanently if you see the message that your computer has been permanently activated. However, if there is a time limit, please note that the date is displayed until when you can use it.
So far, we have looked at how to check the Windows 10 CD key serial number. Have a nice day everyone.^^
