Re: Help! I need a safe Windows 10 product key finder tool, any suggestion?

When I reinstalled Windows 10 before, I also encountered the situation of not being able to find the product key. I tried several methods and finally found the command line tool to be a good choice. It is the simplest Windows 10 product key finder. You don’t need to download additional software. You can directly find the key by entering the command. However, this method does not always succeed. I will share my experience and steps with you.

At that time, my system was pre-installed with Windows 10 by the manufacturer. I thought that the product key should be stored in the BIOS, so I tried to use the command line tool.

1. First, I opened the command prompt, pressed Win+S to search for "Command Prompt", and then right-clicked "Run as Administrator".
2. This step is very critical, because without administrator privileges, the command may not be executed normally.
3. Then, in the command line window, enter:

wmic path softwarelicensingservice get OA3xOriginalProductKey

After pressing Enter, the system starts to read the pre-installed key from the BIOS. After a while, a string of 25-digit keys appeared on the screen, such as:
XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

When I saw this string of numbers, I was so excited that I copied it down immediately and successfully used it for reinstallation and activation. This command is indeed a very convenient Windows 10 product key finder.

However, I have also encountered a rollover. Another computer I assembled myself was empty when I used the same command. Only then did I realize that this method is only suitable for OEM keys (pre-installed systems by manufacturers). For digital authorizations (such as systems activated with Microsoft accounts) or keys purchased by yourself, this command cannot be found at all.

In general, the command line tool is the most basic Windows 10 product key finder and is suitable for a try first. If you have a pre-installed Windows 10 system by the manufacturer, the success rate is very high; but if it is a digital authorization or post-installed system, other methods may be needed, such as using a Microsoft account or special tools to find it. I hope my experience can help you!
