How to Stop Microsoft Edge from Preloading

In October 2018 update of Windows 10, Microsoft Edge received a performance boost, which allowed it to pre-launch processes as well as pre-load the Start & New Tabs during startup. However, if you don’t use Microsoft Edge, these optimizations will be wasting resource and slowing the startup time. With a Registry trick or a small Group Policy setting, you can then disable it.

If your computer is running on Windows Home edition, you need to use Registry Editor to make the changes. You can also do this if your Windows computer is running on Pro or Enterprise, but it will be more comfortable when working in the Registry. You can use the easier Local Group Policy Editor, which will be described below.

How to Stop Prelaunching Microsoft Edge Processes

To proceed, you should first open the Registry Editor by hitting on Start and then type in “regedit.” Open Registry Editor and allow it to make changes to your computer.

In Registry Editor, you can use the left sidebar to head over to the following key (or copy it into the Registry Editor Address bar):

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\Main

Now, right-click on the primary key and then select New > DWORD (32-bit) Value. Name the new value into AllowPrelaunch.

Now, you need to modify that value. Double-click on the new AllowPrelaunch value, and then set the value to 0 in the “Value data” box. Next, click on “OK.”

You can still set back to the default behavior later by returning and changing that AllowPrelaunch value to 1.

How to Prevent Preloading of Start and New Tabs

In the Registry Editor section, use the left sidebar to head over the following key (or copy it into the Registry Editor address bar):

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge

Once done, right-click on the MicrosoftEdge folder and then select New > Key. Name a new key: TabPreloader.

Right click on the TabPreloader key and select New > DWORD (32-bit) Value. Next, name the new value AllowTabPreloading. You need now to modify this value. Double-click on it, and then set the value to 0 in the “Value data” box. Click on OK to apply the change.

Now, simply exit Registry Editor. To make the changes take effect, you need to restart your Windows computer. To get things back to the default behavior, you can return and set that AllowTabPreloading value to 1.

Download One-Click Registry Hack

If you don’t like digging into Registry yourself, here are some Registry hacks that you can use. Simply download and then extract the following ZIP file:

PreventPreloadingAndPre-LaunchingOfMicrosoftEdge

Once extracted, you will find REG files, which is useful to disable pre-launching and preloading. Just double-click on the file and accept popup prompting whether you want to make changes to your Registry. There are also files for re-enabling both features.

These hacks will add the AllowPrelaunch as well as AllowTabPreloading values to the MicrosoftEdge key. They have been created from a custom Registry and then be exported to a REG file. Simply run the hacks to modify the values in Registry. In case you like fiddling with the Registry, it’s worth taking the time to know how to make your own Registry hacks.
