How to disable background throttling on MS edge

Hi Mohammad Alkronz,

Based on your description, the issue occurs because Microsoft Edge applies background timer throttling and Intensive Wake Up Throttling when a tab is minimized or inactive. This can disrupt real-time applications like Cisco Finesse, leading to unexpected logouts.

Here are the steps you can take to resolve this:

1. Use Command-Line Flag

If you launch Edge via a shortcut or script, add:

"C:\path\msedge.exe" --disable-background-timer-throttling 

• Make sure to close all Edge processes before relaunching.
• If you use Run (Win + R), you can simply type: msedge --disable-background-timer-throttling

2. Apply Group Policy (Enterprise-Wide)

For managed environments:

• Download the latest Microsoft Edge ADMX templates.
• In Group Policy: Administrative Templates > Microsoft Edge > Control the IntensiveWakeUpThrottling feature
• Set it to Disabled.
• Registry equivalent (create manually if it doesn’t exist):

    [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge]
    "IntensiveWakeUpThrottlingEnabled"=dword:00000000

3. Verify Sleeping Tabs Settings

• Go to: Settings > System and performance > Optimize Performance
• Disable Sleeping Tabs or add the Finesse URL to the exception list.

Reference: Turn the Sleeping Tabs in Microsoft Edge On or Off

Note:

• These changes can increase CPU usage, so apply only to critical apps.
• For large deployments, Group Policy is the most reliable method.
• Cisco often recommends Firefox for Finesse as it does not throttle background tabs as aggressively.

I hope this helps! If you need anything else - please feel free to ask!
