Microsoft Finally Fixes Error 633 in Windows 10 Creators Update

Microsoft rolled out Windows 10 cumulative update KB4022716 earlier this week, and one of the most important changes that it brings is a bugfix for error 633.

If you’ve never experienced this error, the chances are that you have no idea what it does, though there are thousands or maybe more users out there who have been trying to deal with this since the release of the Windows 10 Creators Update.

In just a few words, this error impacts modems and dial-up connections, causing them not to work correctly, even though everything was just fine before the update to the Creators Update. We’ve also experienced the same bug on at least two Windows 10 laptops here at Softpedia, and finding a workaround was a really difficult job, especially because the typical fixes made no difference.

So if you are also experiencing the same problem and want to have it fixed to continue using a dial-up connection in Windows 10 Creators Update, just download and install Windows 10 cumulative update KB4022716 and everything should return to normal.

The easiest workaround
The only workaround that we tried and which got the modem working on our PCs involved launching the Windows 10 Registry Editor (by typing regedit in the Start menu) and navigating to the following path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan

Look for a key called RequiredPrivileges and double-click to open it. At the end of the text, add a line that’s called SeLoadDriverPrivilege, but make sure you don’t change or delete anything else. Save the changes and click OK – a warning might be displayed, but simply click OK and you’re good to go.

Restart your computer, plug in the modem and re-attempt to connect with the dial-up profile. Everything should work normally even if the aforementioned cumulative update is not installed.

As far as users already running the Windows 10 Creators Update are concerned, they should install the new cumulative update as soon as possible because it brings many other fixes and improvements, all of them refining the overall experience with the OS.
