Learn how to fix, when you can't enable Developer mode in Windows 10 due to "Developer Mode package failed to install. Error code: 0x80004005" message.

In Windows 10, you can activate Developer mode any time to install and test the apps developed by you. Also you can run the apps from Visual Studio in debug mode. Developer mode can be enabled from Settings app > Update & security > For developers > Developer mode. According to Microsoft, when you turn on Developer mode, following operations are performed by Windows:

  • Installing Windows device portal and configuring firewall rules for it
  • Configuration of firewall rules for Secure Shell (SSH) services to allow remote installation of apps
  • Enabling Windows subsystem for Linux that allows you to run Bash on Ubuntu inside Windows operating system (OS)

But some of the users has reported that they when they enable Developer mode, following error message appears:

Developer Mode package failed to install. Error code: 0x80004005

  • Hi in my pc i am not WindowsUpdate folder plz help me how i can Create it ?

  • Kapil Arya

    ^^ Right click Windows registry key (HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows). Select New > Key and name newly created sub-key as WindowsUpdate. Similarly create AU registry key.

  • now it says installing developer mode package and just hangs like that forever

  • Kapil Arya

    ^^ Make sure you’re connected to a fast Internet connection and suggest you to give it some time, it may work!

  • This process didn’t work for me in our Domain Environment. The registry key gets reset after a reboot.

    Instead of rebooting, I changed the registry key mentioned above, then restarted the Windows Update service. I was then able to enable Developer Mode.

  • Thanks, it worked. Small note: enabling developer options (if your company uses WSUS) also works without reboot, if you restart the ‘windows update’ service (eg via services.msc) after changing the mentioned registry key.
