Guide to Checking Microsoft Office License and Identifying Cracked Office

1. Dangerous Consequences of Intentionally Using Cracked Microsoft Office

Many people believe that using cracked Office simply saves them the cost of buying a license. In reality, the price they pay is sometimes many times greater than the cost of investing in genuine software.

1.1. Opening the Door to Malware and Cyberattacks

Most current tools for activating pirated Office require users to disable Windows security features such as Windows Defender or antivirus software.

This is the most dangerous time.

When defenses are disabled, malicious programs can easily infiltrate a computer without the user's knowledge. Common types of malware found in cracked Office suites include:

• Trojan horses steal data.

• Keyloggers record keyboard input.

• Spyware tracks user activity.

• Ransomware encrypts data and demands a ransom.

• Malware steals bank accounts.

For businesses, the risk is even more serious as customer data, business contracts, accounting records, or internal documents can be stolen or leaked externally.

Many cyberattacks today stem from employees inadvertently installing cracked software on their work computers, creating entry points for hackers to penetrate the entire company's system.

1.2. Lack of Features and Unstable Operation

Cracked versions of Office often involve direct interference with the license activation system.

During that editing process, many components of the program may be changed or disabled, causing the software to malfunction.

Users may encounter situations such as:

• Excel freezes when processing large amounts of data.

• The complex calculation function is malfunctioning.

• PowerPoint suddenly closed during a presentation.

• Word failed to save the document.

• Outlook lost connection with the email server.

These incidents not only disrupt work but also seriously damage the professional image of individuals and businesses when working with clients or partners.

1.3. Not Receiving Security Updates

Microsoft regularly releases patches and security updates to fix newly discovered vulnerabilities.

When using a licensed version of Office, your computer will automatically receive these updates through Microsoft Update.

Conversely, cracked Office versions are often blocked from connecting to Microsoft's activation system to avoid detection of invalid licenses.

The consequence is:

• I did not receive the security patch.

• No new features have been added.

• Increased risk of cyberattacks.

• Performance decreases over time.

• Numerous compatibility issues have arisen with the new Windows version.

Maintaining outdated software for an extended period is like leaving your front door open without a lock.

1.4. Risks of Software Copyright Infringement

For businesses, using software without a valid license can lead to legal risks.

During software license audits, businesses may be required to prove their legitimate right to use Microsoft products they are deploying.

If a business fails to provide a valid license, it may face:

• Copyright infringement compensation.

• The cost of acquiring a valid license.

• Impact on brand reputation.

• Loss of trust from customers and partners.

Therefore, checking the validity of Microsoft Office is a task that should be performed periodically on all computers.

2. The Most Accurate Method for Checking Microsoft Office Copyright

There are several ways to verify the activation status of Microsoft Office. Below are some of the most commonly used and accurate methods.

2.1. Direct Testing in Office Applications

This is the simplest method and suitable for all users.

Step 1: Open an Office Application

Launch any Office programs that are installed on your computer.

You can use:

• Microsoft Word

• Microsoft Excel

• Microsoft PowerPoint

• Microsoft Outlook

Word or Excel are usually the most convenient options.

Step 2: Access the Account section

After the program successfully launched:

• Click on File in the upper left corner.

• Find the Account section in the left-hand navigation bar.

• Click to open the account information interface.

Here, Microsoft will display all the product license information.

Step 3: Check Product Information

Observe the Product Information area .

If your Office license is valid, the following screen will appear:

"Product Activated"

Include the specific version name, such as:

• Microsoft 365

• Office Home & Student

• Office Home & Business

• Office Professional Plus

This indicates that Office has been successfully activated.

If the following message appears:

"Activation Required"

This indicates that the software has not been activated or is using a trial version.

If activation error warnings appear, the license is most likely invalid or has expired.

2.2. Checking Office License Using Command Prompt

This is a more reliable method because it can detect illegal activation patterns that are not displayed in the standard interface.

Step 1: Open Command Prompt with Administrator privileges

Press the Start button.

In the search box, enter:

cmd

When the Command Prompt icon appears:

• Right-click.

• Select Run as Administrator.

A black background window will appear on the screen.

Step 2: Enter the Copyright Check Command

Copy the following command exactly:

cscript.exe "%ProgramFiles%\\Microsoft Office\\Office16\\ospp.vbs" /dstatus

Then press Enter .

Note:

The Office16 folder typically applies to Office 2016, Office 2019, Office 2021, and Microsoft 365.

In some cases, Office can be installed at:

cscript.exe "%ProgramFiles(x86)%\\Microsoft Office\\Office16\\ospp.vbs" /dstatus

If the first command gives an error that the file was not found, try the second path.

Step 3: Analyze the Return Results

After a few seconds, the system will display the license information.

Find the line:

LICENSE STATUS

If displayed:

LICENSED

This indicates that Office is properly activated.

If content such as: appears

• KMS_Client channel

• Grace Period

• Notification Mode

• Remaining Grace

Office might be using a KMS activation method or an unlicensed trial version.

This is a method widely used by IT administrators to verify the authenticity of Office licenses in a business environment.

2.3. Checking the COA Certification Stamp

For Office suites purchased in physical boxes, Microsoft provides a certificate of authenticity called a COA (Certificate of Authenticity).

The COA sticker is usually affixed to:

• Product box.

• Software packaging.

• The accompanying documentation is included.

When conducting the inspection, please note:

Hologram stamps must be able to change color when viewed from different angles.

The details printed on the stamp must be sharp.

There are no signs of peeling or tampering.

The Product Key string must match the license provided.

If the label shows signs of counterfeiting or poor printing quality, users should contact the supplier to verify the product's origin.

2.4. Check in the About Window

Microsoft has added an area to display detailed information about product licenses.

Step 1: Access the File

Open Word or Excel.

Click File.

Step 2: Select Account

Continue by selecting Account.

Step 3: Open About

In the Product Information area .

Press the button:

About Word hoặc About Excel

A new dialog box will appear.

Step 4: Compare Information

Here users can view:

• Office version.

• Number of builds.

• Product ID.

• License information.

This information may be used when contacting Microsoft support to verify your license status.

2.5. Using Microsoft's Genuine Product Verification Tool

For large businesses or organizations, Microsoft offers a variety of tools to support license management.

Step 1: Access the Official Microsoft Website

Users should download software verification tools directly from Microsoft to avoid the risk of downloading counterfeit software.

Step 2: Download and Install the Tool

After downloading:

• Save the installation file to your computer.

• Perform the installation.

• Grant administrator privileges when requested.

Step 3: Start the Scanning Process

Open the test program.

The system will automatically analyze:

• Type of license.

• Activated state.

• Source of the license.

• The validity level of the Product Key.

Step 4: View the Results Report

Once completed, the software will provide a detailed report that helps businesses quickly identify devices using invalid licenses.

This method is suitable when you need to test a large number of computers on a local network.
