This tutorial will show you how to enable or disable Process Isolation in Microsoft Edge for all users in Windows 11.
Microsoft Edge is the AI-powered browser. A smarter way to browse. As the only browser built and optimized for Windows, it’s AI-powered tools are designed to help you make the most of your time online. Whether you’re searching, shopping or gaming, AI-powered tools and a security-first approach help you stay productive, save money, and get things done your way.
The ProcessIsolationEnabled policy controls Process Isolation in Microsoft Edge 151+.
When this policy is enabled, Microsoft Edge uses Process Isolation to help improve browser security by preventing authorized applications on the device from reading or modifying the contents of Microsoft Edge's running processes. This also helps prevent other applications from accessing encrypted data used by Microsoft Edge.
Enabling Process Isolation may cause incompatibilities with third party applications that rely on being able to inject or tamper with Microsoft Edge's processes, such as antivirus, screen reader or window manager applications.
Setting the policy to Enabled turns on process isolation in Microsoft Edge.
Setting the policy to Disabled turns off process isolation in Microsoft Edge.
If this policy is unset (not-configured), Microsoft Edge will follow the default rollout process for the Process Isolation feature, which means that the feature will be gradually rolled out to an increasing number of users.
