There are three ways to find the Windows 10 product key: 1. Use the command prompt to execute the wmic command to obtain it; 2. Find the encrypted DigitalProductId through the registry and decode it with tools; 3. Use third-party tools such as ProduKey to view it directly. It should be noted that the OEM system may not be able to obtain the key through the command prompt, while the system activated by the digital license will be automatically activated without the traditional key.

If you need to reinstall the system, transfer the license, or just want to back up your Windows 10 product key, you may be wondering how to find it. Windows will usually automatically activate and bind your device hardware or Microsoft account, but in some cases you still have to manually obtain the key.

Use the command prompt to view the product key

This is the most direct and recommended method. Windows itself does not provide a graphical interface to view existing product keys, but can be quickly extracted via a command prompt (CMD).

• Open the "Start Menu", search for "cmd", and right-click to select "Run as administrator".
• Paste the following code in the command line and press Enter:

 wmic path SoftwareLicensingService get OA3xOriginalProductKey

• The system will display the current computer's product key (if it exists).

Note: Not all computers will display results. If your system is pre-installed with OEM (such as a branded machine), the key may not be returned because the key is embedded in the motherboard rather than stored in the system.

Find keys through the registry (alternative method)

If you cannot use the above method to get it, you can also try to extract the key information from the registry.

• Press Win R to open the run window, enter regedit and press Enter.
• After entering the Registry Editor, expand the path:

 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

• Check out the DigitalProductId item on the right. This value is the encrypted product key and cannot be read directly.
• If you want to restore the key, you can use some third-party tools (such as ProduKey) to decode this ID.

This method is a little more complicated and is suitable for users with certain hands-on ability.

More convenient with third-party tools

If you are not familiar with the command line and the registry, you can also use lightweight tools to help you find the key.

• NirSoft ProduKey is recommended, a green gadget that does not require installation.
• After downloading, open the program and it will automatically scan and display the product keys for the current Windows and other installed software.
• Support remote viewing of other systems' keys (if you have permissions and network access).

Be sure to download it from official or trusted sources to avoid accidentally installing malware.

Basically these are the methods. You can choose the most suitable one according to your operating habits. It should be noted that if you are activated through Windows 10 (binding Microsoft account) through a digital license, you do not necessarily have a "product key" in the traditional sense. At this time, you only need to make sure that your account is logged in correctly and can be automatically activated when reinstalling the system.
