How to Find Microsoft office Product key

The Microsoft Office suite is a widely used collection of productivity applications, including popular programs such as Word, Excel, and PowerPoint. When you install Microsoft Office on your computer, you are usually required to enter a product key to activate the software. This product key is essential for licensing and ensures that you are using a legitimate copy of the software. However, it is not uncommon to misplace or forget the product key. In this guide, we will explore various methods to help you find your Microsoft Office product key quickly and easily.

Check the Product Key Sticker 

The first method involves checking for a product key sticker on the physical packaging of your Microsoft Office software. Retail versions of Microsoft Office often include a sticker with the product key printed on it. Look for the sticker on the DVD case or inside the box. If you purchased a digital download, check your email or the confirmation page for any details regarding the product key. If you find the product key, make a note of it for future reference.

Retrieve Product Key from the Office Account

If you have an active Microsoft Office account associated with your installation, you may be able to retrieve your product key through your account. Follow these steps:

Open a web browser and go to the Microsoft Account login page.
Sign in with the same email address and password you used to set up your Office account.

Once logged in, locate the “Services & subscriptions” or “My Account” section.
Look for your Microsoft Office subscription or purchase and click on it to view details.
Within the subscription or purchase details, you should find the product key associated with your Office installation.

Make a note of the product key for future reference.

Recover Product Key from the Windows Registry 

If you have exhausted the previous methods or if you have an older version of Microsoft Office, you can try recovering the product key from the Windows Registry. However, please note that modifying the Windows Registry can be risky, and it’s advisable to create a backup or consult an IT professional before proceeding. Follow these steps:

Press the Windows key + R to open the Run dialog box.
Type “regedit” (without quotes) and press Enter to open the Registry Editor.
Navigate to the following registry key, depending on your Office version:
For Office 2019 and Office 2016: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\16.0\Registration
For Office 2013: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\15.0\Registration
For Office 2010: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Registration
Expand the “Registration” folder and look for subkeys starting with “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office”.
Click on each subkey and look for the “ProductID” or “DigitalProductID” entry in the right pane.

The value data of “ProductID” or “DigitalProductID” is your Office product key.
Carefully write down the product key.

Contact Microsoft Support

If none of the above methods work, or if you are unable to retrieve your product key through other means, you can reach out to Microsoft Support for assistance. Visit the Microsoft Support website and navigate to the Office section. Find the appropriate contact option, such as live chat or phone support, and explain your situation to the support representative. Provide any relevant details, such as your purchase information or Office account details, to help them assist you in recovering your product key.
