Windows 10 enable Developer Mode error 0x80004005

We want to use the new Windows Subsystem for Linux (Beta) feature that was included with the 1607 build of Windows 10. To do that, you have to enable Developer Mode. But when we tried, we would get the error:

"Developer mode package failed to install. Error code 0x80004005"

The articles I've found that address this error refer to versions that are using a non EN-US language. That is not the case in our organization. In our case, our group policy settings were preventing the OS from downloading the package from Microsoft Update. The following is a workaround that has worked for us. Just be sure to reverse the settings when you're done.

• Launch regedit.exe and modify this key:
• HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
• UseWUServer to 0 (to disable), restart
• Enable Developer Mode, restart
• Enable Windows Subsystem for Linux (Beta), restart
• Launch regedit.exe and modify this key:
• HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
• UseWUServer to 1 (to enable), restart

Hope this helps you as well.
