Disable Microsoft Edge Tab Preloading in Windows 10

Edge Icon Big 256 2

Windows 10 comes with a new default browser, Microsoft Edge. It's a Universal app which has extension support, a fast rendering engine and a simplified user interface. In this article, we will see how to prevent the Edge app from automatically preloading the start and new tab pages when you open the app.

Microsoft Edge can load the Start and New Tab page during Windows sign in and each time Microsoft Edge is closed. By default it is allowed to preload these pages.

Microsoft Edge loads the Start and New Tab page during Windows sign in and each time Microsoft Edge is closed in order to minimize the amount of time required to start up Microsoft Edge and to start a new tab.

If you have issues with this behavior, you can disable it. Starting in Windows 10 version 1809, there is a special Group Policy option which controls the page preloading feature. It can be enabled or disabled with either Local Group Policy Editor or REGEDIT.exe. Here is how.

To disable Microsoft Edge tab preloading in Windows 10, do the following.

  1. Open Registry Editor.
  2. Go to the following Registry key:

    Tip: See how to jump to the desired Registry key with one click.

    If you do not have such a key, then just create it.

  3. Here, create a new 32-bit DWORD value AllowTabPreloading. Note: Even if you are running 64-bit Windows, you still need to use a 32-bit DWORD as the value type.
    Leave its value data as 0 to disable the tab preloading feature.
  4. To make the changes done by the Registry tweak take effect, you need to sign out and sign in again to your user account.

Later, you can delete the AllowTabPreloading value to restore defaults.

Disable Microsoft Edge tab preloading in Windows 10 for all users

To disable the Microsoft Edge pre-launching feature for all users, ensure that you are signed in as Administrator before proceeding.

    1. Go to the following Registry key:

      Create the same value here, AllowTabPreloading, as described above.

    2. Tip: You can switch between HKCU and HKLM in Windows 10 Registry Editor quickly.
    3. Restart Windows 10 to apply the restriction and you are done.

Using the Local Group Policy Editor app

If you are running Windows 10 Pro, Enterprise, or Education edition, you can use the Local Group Policy Editor app to configure the options mentioned above with a GUI.

  1. Press Win + R keys together on your keyboard and type:

    Press Enter.

  2. Group Policy Editor will open. Go to User Configuration\Administrative Templates\Windows Components/Microsoft Edge.
  3. On the right, configure the policy option Allow Microsoft Edge to start and load the Start and New Tab page at Windows startup and each time Microsoft Edge is closed. Set it to Prevent tab preloading.

That's it.

  1. It would be nice if the option of disabling MS Edge tab preloading be added into a future version of Winaero Tweaker

  2. you’re welcome Sergey. it looks like build 17763.1 could be the rtm release of Win10 v1809 RS5.
    trying it recently on a spare PC and only the group policy procedure of disabling Edge preloading works.

    this never worked for the 1803 version but in the 1809 release it works as expected

  3. Note, that “AllowPrelaunch” is in a different location in 1803 and 1809.

    reg add “HKCU\Software\Policies\Microsoft\MicrosoftEdge” /v “AllowPrelaunch” /t REG_DWORD /d “0” /f
    reg add “HKCU\Software\Policies\Microsoft\MicrosoftEdge\Main” /v “AllowPrelaunch” /t REG_DWORD /d “0” /f
    reg add “HKCU\Software\Policies\Microsoft\MicrosoftEdge\TabPreloader” /v “PreventTabPreloading” /t REG_DWORD /d “1” /f
    reg add “HKLM\Software\Policies\Microsoft\MicrosoftEdge” /v “AllowPrelaunch” /t REG_DWORD /d “0” /f
    reg add “HKLM\Software\Policies\Microsoft\MicrosoftEdge\Main” /v “AllowPrelaunch” /t REG_DWORD /d “0” /f
    reg add “HKLM\Software\Policies\Microsoft\MicrosoftEdge\TabPreloader” /v “PreventTabPreloading” /t REG_DWORD /d “1” /f

  4. The Winaero Tweaker app seems to only Disable Microsoft Edge Tab Preloading and Edge Prelaunching on a per-user basis, never “system wide” or for all users.

    Maybe add the options “Disable Edge Prelaunching for all users” and “Disable Edge Tab Preloading for all users” into a future release of Winaero Tweaker, Sergey.
