Dial-up error 633

This error appeared with the US Robotics USR5637 USB dialup modem when Windows 10 was updated to the Creator version (1703), and may also have appeared with other USB modems and devices.

Before attempting to fix the problem ensure that all doftware is up to date:

This may fix the problem, particularly if Windows 10 has been updates with a solution.

If the problem is not fixed, the next step is a change to the Windows 10 Registry. Changes to the Registry can be quite risky - a mistake can make the computer unusable. Registry changes should be carefully made by a technically knowledgeable person.

The required registry change is described at Dial-up error 633 w/build 15063 (1703 Creators) Pro. The change is made by adding one extra line (SleLoadDriverPrivilege) to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\RequiredPrivileges without changing any of the previously existing lines.
