Windows 10: Since Creators, USB modem works on Tablet but not on Laptop Solved

    Since Creators, USB modem works on Tablet but not on Laptop SOLVED

    I have a (ZTE) USB modem that I use to connect to the internet over the mobile/cell phone network. Since "upgrading" my laptop to Win 10 Creators edition, I have not been able to launch a connection. The (telstra) dialling app returns "The modem (or other connecting device) is already in use or is not configured properly."

    However, exactly the same setup on my Tablet computer works just fine. Same OS, same dialler sotware, same drivers, same device.

    I have removed/reinstalled the drivers, and dialler software.

    I infer that something else on my Laptop is conflicting, but don't know what.

    I have tried everything in here:
    Fix: Error 633 Modem (or other connecting device) is already in use -

    The stuff (5 and 6) about conflicts on port 1723 looked hopeful, but didn't help. Is it possible I am using a different port? If so, how do I find out which one?

    the nets.txt text is here:
    'Untitled Post' |

    any ideas ?


    The (problem) laptop is a Lenovo Yoga2pro, Win 10 Home Build 15063.332, 64bit, i7-4300U
    The (no problem) tablet is a Tesco Connect, Win 10 Home Build 15063.332, Atom Z3725G "32-bit OS, x64-based processor"

    Hi BobSter2

    When I searched your issue it looks like lots of people are experiencing and has been an issue for some time.

    I found this. According to article it helped 190 people.

    Now before doing anything with the registry research backing up and restoring registry. I would also recommend creating a restore point and would go a step further in creating an Image using a tool like Macrium Reflect. Its free and recommended by forum members, there is even a tutorial on the subject.

    I do not use such a modem and I have not tried the registry mod.

    While it may not be the most desirable solution, falling back to the Anniversary update may be the best solution. Then setting Windows not to update on Metered Connections (of course you would have to tell Windows this is a metered connection.)

    I believe another cumulative update is schedule for this Tuesday. You may also wish to wait to see if this contains possible fix. Shawn usually posts an update as to what is in update on the forum in the "Windows 10 News" section.

    You can manual download the update on a working machine at Before manually installing issue this command to stop the windows update service.

    net stop wuauserv

    After the install, reboot.

    Hi, yes I looked for a button to do that, but couldn't find one.

    I have edited the thread title now. Let me know if I need to do anything else. Thanks again.

    The June 2017 Patch Tuesday updates seem to have fixed the source of the problem - now no need for the Registry mod. FYI.
