Fix: Enabling Windows 10 Developer Mode get error code 0x80004005 after Build 14383
Some new developers will have problems to enable Developer mode they will get error code 0x80004005 after Build 14383, when trying to enable.
Here is the Known Problem log from Windows Insider Hub
After you install this build (as well as Build 14383) on a PC using a non-EN-US language, you may get error code 0x80004005 when enabling Developer Mode on the “For Developers” Settings Page. Even after seeing this error message, your machine is in developer mode and you should still be able to use Visual Studio to develop Universal Windows Applications. In most cases, this error indicates that extra components required by the operating system to enable additional debugging features in Visual Studio or the Windows Device Portal could not be installed automatically.
To fix this:
Open the Settings app.
Click on “Apps & features”
Choose “Manage Optional features”
Press the button “Add a feature”
Select the package for Windows Developer Mode
Reboot your PC
Launch Command Prompt as Administrator
Run: sc config debugregsvc start=auto
Run: sc start debugregsvc
Finally, return to the “For Developers” Settings page. You will still see the error code, 0x80004005 but you should now be able to enable Windows Device Portal and the Device Discovery features
I have not been able to test this because this is already enabled on my PC
