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.

Edge Process Monitor log and crash dump (if any)

This action plan is used to troubleshoot any Edge startup failure or crash issue, regardless of the web application it loads. If the Edge crash issue only occurs when loading a specific website, you should refer to the Edge crash dump, Fiddler, Process Monitor log to capture logs.

Clone recipe

Prerequisites

  1. Download and unzip Process Monitor from https://learn.microsoft.com/en-us/sysinternals/downloads/procmon.

  2. Search for environment in Windows and open Edit the system environment variables and click the Environment Variables... button to open the editing page.

  3. Create a new user variable as follows:

    Variable name: ENABLE_HEAP_DUMPS

    Variable value: 1

  4. The setting will only take effect after you close all existing Edge processes (msedge.exe) and start a new Edge window.

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

  6. 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

Main steps

  1. Close all instances of Edge. Open the Task Manager and check the process list in the Details tab. Sort the processes by Name. Ensure that you do not see any msedge.exe process in the list. If there is any remaining msedge.exe process, kill it.

  2. Launch Procmon.exe as administrator from the location where you unzipped the Process Monitor. It should automatically start capturing after startup. Proceed to the next step when you see that it is generating a large number of events.

  3. Start Edge and reproduce the issue. Proceed to the next step after issue being reproduced.

End steps

  1. Go to Process Monitor, press Ctrl+E or click the third Capture icon to stop capturing.

  2. Click File -> Save. Choose All events and then save the log in pml format.

  3. Check if any Edge crash dumps have been created at %LOCALAPPDATA%\Microsoft\Edge\User Data\Crashpad\reports, you may zip the entire reports folder to reduce the dump file size.

    Note: for other channels, the dump location will be %LOCALAPPDATA%\Microsoft\Edge <channel>\User Data\Crashpad\reports, where <channel> is SxS (Canary), Dev or Beta.

  4. Since full crash dumps take up a lot of disk space, it is suggested to remove the user variable: ENABLE_HEAP_DUMPS if full crash dumps are no longer needed.

  5. Navigate to the edge://policy page in Edge. Click the Reload Policies button. Click the Export to JSON button to save the policies.json.

  6. Navigate to the edge://version/?show-variations-cmd page in Edge. Press Ctrl+S or right click the page and click Save as to save the page in HTML format.

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

  8. 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.
