How To Disable Edge Preloading On System Boot On Windows 10

Microsoft Edge is the stock browser that Windows 10 ships with and most users ignore it. Not many have given it a try and those that have, aren’t tempted enough to use it as their default browser. It has some good features and you can watch Apple events on it from a Windows machine but it’s still lacking in a few areas. While users can change the default browser on Windows 10, they still need an app called EdgeDeflector if they want to prevent all web requests from opening it. Even with this app, when you boot to your desktop, Edge still runs. It is eventually suspended but it does make its (minor) impact on start up. Here’s how you can disable Edge preloading on system boot on Windows 10.

Disable Edge Preloading

You can disable Edge preloading through both the Group policy and the Windows registry. Using the Windows registry is probably a good idea because you can backup a key and restore it if you want, and it works on all versions of Windows 10.

Open the Windows registry. You will need administrative rights to make changes to it. In the registry, go to the following location;

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\Main

Right-click the Main key and select New>DWORD(32-bit) value from the context menu. Name this new value¬†AllowPrelaunch. Once created, double-click it and set its value to 0. If the value is already set to 0 by default then your work is done. This alone isn’t enough. Edge also runs a few additional services that you need to disable.

In the Windows registry, go to the following location;

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\TabPreloader

Right-click the TabPreloader key and select New>DWORD(32-bit) value. Name it AllowTabPreloading and again, set its value to 0.

This ought to do the trick. If you use Edge on occasion, you will find that it might take a bit longer to start. If your Windows installation doesn’t have the Microsoft Edge key, or the Main and TabPreloader keys under it, you can create them.

Right-click the Microsoft key and select New>Key to create the Microsoft Edge key. Right-click the Microsoft Edge key and again select New>Key to create the Main key under it. Follow suite to add the TabPreloader key. You can delete these keys later but doing so will also delete the DWORD values you added under it. The absence of these keys doesn’t mean that Edge doesn’t preload on your system when you boot to your desktop. It’s a good idea to backup your registry before you make this change.
