How to Disable Microsoft Word Security Notice Pop-up?

Microsoft Security Notice is intentional by Microsoft to warn its users about the content (like hyperlinks) that can share data with external files and websites.

It pops up is when a user tries to paste contents from the web or other sources in a Word file or any other office application. He receives the following message:

Microsoft Word Security Notice

A one-time message would not have bothered users, but whenever pasting contents to the Office applications, this becomes troublesome. Moreover, this feature broke many of the macros/ automated tasks by the individuals or organizations and caused a lot of trouble.

You can turn off security notice in Word by either updating the Office Installation or reverting it to the older version of Office (as discussed later) but before that, check if pasting the web contents only either image or text (without hyperlinks) by editing the formatting of copied text from the internet fulfills your needs.

Keep Text Only of the Copied Contents in Microsoft Word

Update the MS Office of Your PC to the Latest Build

The Word security Notice pop-up is a result of a reported bug in the office installation and updating the MS Office to the latest build may solve the problem.

  1. Launch an MS Office application (like MS Word) and create a new document in it.
  2. Now, in the Ribbon, head to its File tab and select Account.
  3. Then expand the drop-down of Office Updates (in the right pane) and select Update Now.
    Update Office Application
  4. Now, wait till the office installation is updated to the latest build and then relaunch MS Word to check if it is clear of the security notice pop-up.

If you are one of those users who are encountering the Microsoft Security Notice pop-up even when no office application is operating, then either check if any of the other applications (Signature Manager is reported to cause the issue) is causing the issue or perform a clean boot of your Windows 10 PC to find the problematic application.

Roll Back the Office Installation of Your PC to the Previous Release

If updating the MS Office is not an option, then rolling back the office installation to the previous release may disable the potential security concern pop-up.

  1. Firstly, exit all the Office applications and end any of the MS Office processes in the Task Manager of your system.
  2. Then click Windows, key-in CMD, in the results displayed, right-click on Command Prompt, and select Run as Administrator.
    Open Command Prompt as Administrator
  3. Now execute the following:
    "C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user forceappshutdown=true updatetoversion=16.0.14026.20308

    where C is your system drive.

  4. Once completed, check if MS word is clear of the security notice pop-up.
  5. If so, then launch an office application (like Microsoft Word) and open a new document in it.
  6. Now, on the Ribbon, head to the File tab and select Account.
  7. Then expand the dropdown of the Office Updates and select Disable Updates.
