How to Fix an Expired Security Alert in Word 2010
Question details
The user needs to resolve an expired or invalid security alert message that appears when opening certain documents in Word 2010.
- Product
- Microsoft Word 2010
- Device & OS
- not provided
- Scenario
- Opening specific documents containing signed macros, linked content, or outdated certificates.
- Observed behavior
- Word displays a popup warning stating that a security certificate has expired or is not yet valid.
Ensure you only open documents from trusted sources, as Office 2010 is no longer supported and lacks modern security updates.
Verify and Correct Windows System Date and Time
An incorrect system clock is the most common cause of certificate validity errors. Syncing your clock can resolve the alert immediately.
Security certificates rely on your computer's clock to verify their validity period. If your system date is behind or ahead, valid certificates may appear expired or not yet valid.
Right-click the clock in the Windows taskbar at the bottom right corner of your screen and select 'Adjust date/time'.
Ensure that the options for 'Set time automatically' and 'Set time zone automatically' are toggled on.
Click the 'Sync now' button to manually force an update of your system clock with the Windows time server.
Close Microsoft Word 2010 completely and reopen the document to see if the security alert has disappeared.
Check Document Content and Trust Center Settings
If the error occurs only with specific documents, it may be due to embedded macros or linked content with genuinely expired certificates.
Upgrade to WPS Office for a Secure, Modern Experience
Microsoft Office 2010 has reached the end of its support lifecycle, meaning it no longer receives security updates or certificate renewals. WPS Office provides a free, highly compatible, and secure alternative with a familiar interface to keep your workflow uninterrupted without legacy security warnings.
- 1. Download the Installer: Visit the official WPS website and click 'Download WPS Office Free' to get the latest secure version.
- 2. Install the Software: Run the installer and follow the simple on-screen instructions to set up WPS Office on your computer.
- 3. Open Your Documents: Right-click your existing Word document, select 'Open with', and choose WPS Office to view and edit your file without expired certificate alerts.
Frequently Asked Questions
Why am I getting a security alert about an expired certificate in Word 2010?
This usually happens when your computer's system date and time are incorrect, or the specific document contains digital signatures, macros, or linked web content whose security certificates have genuinely expired over the years.
Is Microsoft Word 2010 still safe to use?
Office 2010 reached its official end of support in October 2020. It no longer receives technical support, bug fixes, or critical security updates from Microsoft, making it increasingly vulnerable to modern security risks.
How do I turn off security alerts in Word 2010?
While you can adjust macro and active content settings via File > Options > Trust Center > Trust Center Settings, it is highly recommended not to disable security alerts completely, especially on an unsupported version of Office, as this leaves your computer exposed to malicious files.
