How to use a KMS license key to activate Office 2010/2013 for free 2026You are aware that I am working on a project that helps individuals activate Microsoft software products with the help of a KMS license key. I’m sure there are a lot of you who are wondering why I only write guidelines for Office 2016 or Office 365. Is it possible to get a free activation for older versions? Yes, this is very likely, but there is a problem that needs to be discussed in greater detail below.
The difference between the volume and retail versions
The KMS method does not work with Office retail because it only supports volume versions. However, since Office 2016 included a license files library in the setup file, users can now convert the retail version to a volume, making KMS license use much simpler. However, it is unfortunate that earlier versions of Office—including Office 2013 and 2010—do not include this library.
Introduction: Understanding KMS Activation for Microsoft Office (2026)
How to use a KMS license key to activate Office 2010/2013 for free 2026
Microsoft Office activation is designed to ensure that users run genuine, licensed software. One of the official activation methods provided by Microsoft is KMS (Key Management Service). KMS is not a free activation tool, but an enterprise licensing system intended for organizations such as companies, colleges, and government institutions.
In 2026, although Office 2010 and Office 2013 are discontinued and no longer supported by Microsoft, many organizations still maintain legacy systems where these versions exist under valid volume licensing agreements.
Understanding how KMS works—legally—is important for IT students, system administrators, and users working in corporate environments.
Hey—quick heads-up before we go further 🙂
I can’t help with instructions to activate Microsoft Office using KMS keys “for free” or bypass licensing. That falls under software piracy/circumventing safeguards, which I have to say no to.
But I’ve got your back with safe, legit alternatives—and I can still give useful, high-level info without step-by-step misuse. Here’s the best way forward 👇
What I can explain (high level)
What KMS activation is (legit context)
KMS (Key Management Service) is designed for organizations (companies, colleges, government).
It activates Office/Windows inside a licensed network using a volume license.
End users don’t activate Office themselves—IT admins handle it.
Using KMS outside an organization is not legal.
That’s the limit of explanation I can provide on KMS.

1. The first method: Without using any additional library
How-to video
The Office 2010 and 2013 Volume editions are supported products.
To begin, you’ll need to open the command prompt with admin rights. Then, proceed through the steps listed below. Simply copy and paste the commands, then press Enter to carry them out.
Step 1.1: Find where Office is installed on your computer.
The path is determined by your Windows OS’s architecture. Don’t worry if you don’t know what it is; just run the commands below.
if exist "%ProgramFiles%\Microsoft Office\Office15\ospp.vbs" set folder="%ProgramFiles%\Microsoft Office\Office15"
if exist "%ProgramFiles(x86)%\Microsoft Office\Office15\ospp.vbs" set folder="%ProgramFiles(x86)%\Microsoft Office\Office15"
if exist "%ProgramFiles%\Microsoft Office\Office14\ospp.vbs" set folder="%ProgramFiles%\Microsoft Office\Office14"
if exist "%ProgramFiles(x86)%\Microsoft Office\Office14\ospp.vbs" set folder="%ProgramFiles(x86)%\Microsoft Office\Office14"
Open Office folder
Step 1.2: Activate your Office using KMS client key.
2. The second approach is to use an additional library that has been extracted from the Office Volume installation folder.
After ensuring that your computer is online, run the following command.
cscript %folder%\ospp.vbs /act
note If you receive the error code 0xC004F074, either the server is busy or your internet connection is unstable. Please verify that your device is connected to the internet and try the command "act" once more until you succeed.
Product activation successful
2. The second approach is to use an additional library that has been extracted from the Office Volume installation folder.
All versions of Office 2013 and 2010 are supported.
Step 2.1: Extract the license files library you downloaded earlier. Move the folder for the library to the C drive.
Office additional library
Step 2.2: Proceed with method 1’s first step.
Step 2.3: Change your retail license into a volume one license.
cd /d c:\library
for /f %x in ('dir /b *') do cscript %folder%\ospp.vbs /inslic:%x
Step 2.4: Proceed with method 1’s second step.
Office is activated successfully
More information:
The library’s virustotal score is as follows: Office 2010 lib | Office 2013 lib I am aware that many of you feel uneasy using the library. I didn’t want to write about Office 2010 and 2013 because of this. Please use the Office 2010/2013 volume or upgrade to a newer version if you dislike using the additional library.
Please leave your comments if you have any questions or concerns. I’d be happy to go into more detail. Thank you so much for your assistance and feedback!
