Disable Enhanced Security in Internet Explorer on Windows Server 2019


Method 1 - Disable via Server Manager

Start Server Manager.

Click Local Server in the left menu.

On the right side you will see the IE Enhanced Security Configuration parameter. Click On next to it.

In the window that appears, disable this option for administrators and users and click OK.

Server Manager will show Off for IE Enhanced Security Configuration after a few seconds. If it doesn't, try updating the window contents.

You can now fully use Internet Explorer on Windows Server 2019.

Method 2 - Disable via PowerShell

Open PowerShell.

Paste the following script there and press Enter. Sometimes a double tap is required.

function Disable-IEESC { $AdminKey = "HKLM:\SOFTWARE\Microsoft\Active Setup\Installed Components\{A509B1A7-37EF-4b3f-8CFC-4F3A74704073}" $UserKey = "HKLM:\SOFTWARE\Microsoft\Active Setup\Installed Components\{A509B1A8-37EF-4b3f-8CFC-4F3A74704073}" Set-ItemProperty -Path $AdminKey -Name "IsInstalled" -Value 0 Set-ItemProperty -Path $UserKey -Name "IsInstalled" -Value 0 Stop-Process -Name Explorer Write-Host "IE Enhanced Security Configuration (ESC) has been disabled." -ForegroundColor Green } Disable-IEESC

Internet Explorer now works in normal mode.
