“Developer mode package failed to install. Error code 0x80004005”. A few people, including me, faced issues when trying to enable developer mode in Windows 10. This guide will show you how to fix it.
Why this happens?
After quite some digging and research online, I found that this problem is related to WSUS (Windows Server Update Services). If you’re in an environment where your PC gets updates from WSUS, you can face this problem. Luckily, it’s a straightforward fix.
Click Start and type
regedit. Open it.
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU in regedit
Double click UseWUServer and set the value to 0
Restart your PC. Now try to enable developer mode again. This time you will not see the error 0x80004005 and it should be enabled successfully.
