IE Security Zones test domains
Internet Explorer assigns all websites to one of four security zones: Internet, Local intranet, Trusted sites, or Restricted sites. The zone to which a website is assigned specifies different security settings that may lead to different behaviors. Following domains allow you to test the browser labs in different security zones in IE. Before navigating to following domains, you need to either map these domains into the correct security zone manually or run following command to map these domains automatically.

Disable Edge Startup boost

Prerequisites

  1. Access edge://settings/system in Edge and disable Startup boost.

  2. If the setting is greyed out, please launch a CMD or PowerShell window as administrator and execute following command:

    REG ADD "HKLM\SOFTWARE\Policies\Microsoft\Edge" /v StartupBoostEnabled /t REG_DWORD /d 0 /f

End steps

  1. If you want to re-enable Startup boost, you can enable it from edge://settings/system page.

  2. If the setting is greyed out, please open Registry Editor as administrator and find if any of the following registry keys is set to 0.

    • HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\StartupBoostEnabled
    • HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Edge\StartupBoostEnabled

    If either of these keys is present, remove them to allow you manually toggle the setting in the edge://setting/system page. Alternatively, you can set the value to 1 to enable Startup boost.

    Note: If both keys are present, the one in HKEY_LOCAL_MACHINE takes precedence.
