Method 1: Using Edge Settings Open Microsoft Edge Go to Settings Default browser. Find “Allow sites to be reloaded in Internet Explorer mode.” Choose one of the following options. Default: lets Edge decide based on recent IE usage. Allow: lets users reload pages in IE mode. Don’t allow: prevents IE mode completely. Click Restart to apply the change. Method 2: Using Group Policy While the previous method is fine for testing, it's not scalable. This is where Group Policy comes in. Download and install the latest Microsoft Edge ADMX templates from Microsoft. Open the Group Policy Editor as Administrator. Navigate to: Computer Configuration Administrative Templates > Microsoft Edge Double-click Configure Internet Explorer integration, set it to Enabled, and then choose: Internet Explorer Mode: uses IE rendering inside Edge. None: disables IE mode. Internet Explorer 11: opens IE directly. Click OK. Once finished, restart Edge or the device to apply the policy. Method 3: Using the Windows Registry Open Registry Editor as Administrator, then go to: Create or modify a DWORD named InternetExplorerIntegrationLevel and assign a value: 0: Disable IE mode 1: Enable IE mode 2: Launch IE as a standalone browser Optionally, create a REG_SZ named InternetExplorerIntegrationSiteList and enter the path or URL of your XML site list. Restart Edge or the PC to apply the changes. Again, remember to back up the registry before making any changes. Method 4: Using PowerShell In PowerShell, you can create or modify the same registry keys programmatically to automate IE mode configuration across devices. You’d typically use commands like New-Item, Set-ItemProperty, and Remove-ItemProperty to enable or disable IE mode and define your XML site list. If you want the exact PowerShell script for both enabling and disabling IE mode, including syntax and XML examples, check out the full blog post linked below. Method 5: Using a .REG File Finally, you can use a simple .reg file to import registry settings directly. This is useful for quick, manual configuration or semi-automated deployment. To enable IE mode, create a file with these contents: Save the file with a .reg extension, double-click it, confirm the UAC prompt, and restart Edge. IE mode should only be enabled in managed, legacy-dependent environments. For most users, keeping it disabled is the more secure and future-proof option. This also helps centralize browser usage across an organization.
