Symptoms


When you perform an in-place upgrade to Windows 10, version 1809, version 1709, version 1703, or version 1607, the third-party network provider settings are removed from the computer.

Cause


This is a known issue in the Windows 10 upgrade process. After the upgrade, the Provider list (HKLM\SYSTEM\CurrentControlSet\Control\NetworkProvider) is reset, and the third-party provider registry settings (under HKLM\System\CurrentControlSet\Services\) are removed.

Workaround


Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, go to the following Microsoft Knowledge Base article:
322756 How to back up and restore the registry in Windows

To work around this issue, use one of the following methods.
 

Method 1

  1. Before you upgrade, manually back up the contents of the Provider list at HKLM\SYSTEM\CurrentControlSet\Control\NetworkProvider and the respective third-party provider settings (under HKLM\System\CurrentControlSet\Services\).
  2. Run the upgrade.
  3. After the upgrade is completed, restore the registry settings that were backed up in step 1.
     


Method 2

If you are experiencing issues that affect the third-party network provider settings after you upgrade, manually restore the registry keys that were deleted by the installer.
