If you never use this browser, there is no reason why it should start in the background. This is why some users prefer to disable Edge operation in the background.
If you’re using Windows 10, you may have noticed Microsoft Edge processes running in Task Manager or another program, even if you haven’t opened the program. Such processes appear as suspended in the task manager, so they are not using CPU or memory anyway. Here’s how to prevent Edge from running in the background.
Lock Microsoft Edge in the background
Keep in mind that you can run Edge on your device whenever you want. Editing the Windows Registry and a change in Settings are required.
1. In the Settings application
Use the Windows + I shortcut to open the Settings app on your Windows 10 PC or device.
Go to Privacy and select Background apps at the bottom in the sidebar on the left.
In the app list, find Microsoft Edge and turn off the switch next to it.
2. In the Windows Registry
You need elevated privileges to edit the registry. I recommend you make a backup copy of it before making the changes.
# 1. Press the Windows key, type regedit, and press the Enter key on your keyboard to start the Registry Editor.
# 2. Confirm in the User Account Control screen that is displayed and when you open the Editor go to the following string:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ MicrosoftEdge \ Main
# 3. If Main doesn’t exist, right-click on MicrosoftEdge and select New > Key, and name it Main.
# 4. Right-click Main, select New > Dword Value (32-bit), name it SyncFavoritesBetweenIEAndMicrosoftEdge, and set its value to 1.
# 5. Right-click Main, select New > Dword Value (32-bit), name it PreventLiveTileDataCollection, double-click it, and set its value to 1.
# 6. Right-click Main, select New > Dword Value (32-bit), name it AllowPrelaunch, and make sure the value is set to 0 (it’s the default).
# 7. Go to HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ MicrosoftEdge \ TabPreloader
If TabPreloader doesn’t exist, right-click on MicrosoftEdge and select New> Key, and name it TabPreloader.
# 8. Right click on TabPreloader, select New > Dword Value (32 bit), name it PreventTabPreloading, double click and set its value to 1.
# 9. Right click on TabPreloader, select New > Dword Value (32 bit), name it AllowTabPreloading and make sure its value is set to 0.
# 10. Restart the computer.
Microsoft Edge processes should disappear after reboot. You can undo the change by removing the mentioned keys and values ??or by restoring the registry backup if you made it at the beginning. This will allow Edge to run in the background again.
