Perform a Clean boot

Third-party applications can sometimes interfere with Windows 10 installation, and if you keep getting 0x800704DD-0x90016, perhaps you should try disabling the startup applications and services. This is quite simple to do, and you can do it by following these steps:

• Press Windows Key + R, enter msconfig and click OK or press Enter.
• System Configuration window appear. Go to the Services tab. Now you need to check Hide all Microsoft services option and click the Disable all button.
• Now go to the Startup tab and click Open Task Manager.
• List of all applications will now appear. Now you need to disable all startup applications. To do that, right-click the first application on the list and choose Disable. Repeat this for all entries on the list.
• After disabling startup applications, go back to the System Configuration window. Now click Apply and OK to save changes and restart your PC.

After doing that, all startup applications will be disabled. Now try to install Windows 10 again and check if the issue is still there.
