Users attempting to upgrade computers to the Windows 10 Creators Update with a Broadcom 440x 10/100 Integrated Controller LAN adapter device installed, should either block the device or refrain from upgrading. It turns out the adapter can be a major blocker or cause stability problems during or after the upgrade. A forum participant on the Microsoft Community forum is recommending fellow users block the device within their BIOS in order guarantee a successful upgrade. A Microsoft employee, Travis [MSFT], confirms the bug in the Creators Update affecting the Broadcom 440x driver. Here is what he had to say:
Hello. I am an Engineer in the Windows Networking team. I can confirm that there is a bug in the Creators Update that affects the compatibility with the Broadcom 440x driver. We are working on resolving this until it is resolved. We are looking at putting a upgrade block in place as erpmanila3w suggested.
Thank you for reporting this! I will keep this thread posted if there are any updates. Meanwhile following the steps mentioned in this thread will work around the issue (if you can call disabling Ethernet a valid workaround) until we have a real fix available.
If you have any questions please let me know. Source
