How to Enable or Disable SSL Certificate Error Overrides in Microsoft Edge in Windows 10
Microsoft Edge is a new web browser that is available across the Windows 10 device family. It is designed for Windows 10 to be faster, safer, and compatible with the modern Web.
Web security certificates are used to ensure a site that users go to is legitimate, and in some circumstances, encrypts the data.
By default, Microsoft Edge allows overriding of the security warnings to sites that have SSL errors, bypassing or ignoring certificate errors.
Starting with Windows 10 build 17713 (announced in Windows 10 build 17723), you can use a new Prevent certificate error overrides group policy to enable or disable users from bypassing the security warning to sites that have SSL errors.
This tutorial will show you how to enable or disable web security SSL certificate error overrides in Microsoft Edge for all users in Windows 10.
You must be signed in as an administrator to enable or disable certificate error overrides in Microsoft Edge.
