How to prevent Windows 10 from installing a new build automatically

As you might be knowing, Windows 10 Technical Preview updates itself automatically. It has Slow Ring and Fast Ring update settings which define how often you receive a new build via Windows Update. Once a new build becomes available for your update ring in Windows 10, it will be installed automatically. If you wish to stay with a particular build and prevent Windows 10 from installing the new build, I would like to share a simple tip which will help you remain on the current build you have installed.

To prevent Windows 10 from installing a new build automatically, we need to apply a simple Registry tweak.

  1. Open Registry Editor.
  2. Go to the following Registry key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability\RecoveredFrom

    If you do not have the RecoveredFrom subkey, then just create it.
    Tip: See how to jump to the desired Registry key with one click.

  3. Create a new DWORD value here, named after the build number which is available through Windows Update. For instance, if you are running Windows 10 build 9926 and would like to avoid builds 10041 and 10049, then you need to create two DWORD values named 10041 and 10049 respectively. Set these values to 1 as shown below:

    Now, Windows 10 Technical Preview will not be updated to the specified builds. If you later decide to update your Windows 10 Technical Preview, just delete the Registry values you created. You can download a sample Registry file for this tweak here:

    That's it. This tweak works in all Windows 10 Technical Preview builds available at the moment of this writing, however, it can stop working in the future. Tell us which build you stayed with and why.

  1. Thanks Sergey! Very helpful. I see no point in upgrading massive 3gb iso files for mere one or two additional features.

  2. Hi, can i prevent upgrade build 10586 to build 14393 by this way?
    I want receive updates for build 10586. for example 10586.494 but i want prevent it to upgrade new builds.

  3. As of build 17063, this does not appear to work. Modified the registry as described and build 17083 still tries to install, and when it does it shuts down the computer with a GSOD.
