can not remove unknown devices in device manager

Anonymous

I suddenly have a bunch of unknown devices showing up in Device Manager - seems to have started around March 28, 2012....the first one, now there are 16 of them. All are under Network Adapters with the same hardware Id of MS_ASWEBRMP. I can disable them in Device Manager but not uninstall them. And on occasion, after reboot, Windows will automatically discover the very same device and attempt to install it...that's why there are 16 of these devices now. Can not remove these from the registry either no matter what I do for setting permissions and or group policies.

I'm running Windows 7 Professional 64-bit on a Dell Studio XPS 1645. Interestingly enough on my other Dell Laptops with Windows 7 Home (with same Lan and Wireless adapters) these unknown devices do not show up.

Any help would be appreciated...I'm out of ideas, and Dell support has no idea either. They refer me to Microsoft for Windows 7 support, insisting it has to be an OS issue.

    Hi Jay,

    The only relation that i found to aswebr.sys is to a "ndis im driver"

    http://systemexplorer.net/file-database/file/aswebr-sys

    http://msdn.microsoft.com/en-us/library/windows/hardware/ff556921(v=vs.85).aspx

    http://msdn.microsoft.com/en-us/library/windows/hardware/ff565778(v=vs.85).aspx

    http://msdn.microsoft.com/en-us/library/windows/hardware/ff565773(v=vs.85).aspx

    This is a very unusual and rare problem as i haven't found a lot of information on it.

    I don't think that this could be any form of malware, but the signs are definitely

    pointing in Microsofts direction in terms of where this problem came from.

    Jay, thanks for advising that reinstalling does not silve the problem, I was just about to do that. Will wait and see MS has an answer. It does not seem to have an effect on the laptops performance on my side (until now).

    Regards

    Daniel

    What does it say in the properties of the device under details? Go to device manger- network adapters-unknown device- properties- details. I would like to know what is says under the heading "value". 

    It says Hardware Id value ms_aswebrmp

    Hi Jay,

    I am having exactly the same problem, witj 90+ unknown devies installed and

    I haven´t found a solution neither.

    Looks like the only solution will be a reinstallation of w7.

    Hi Daniel,

    Seems we're in the same boat. And so far there's no answers from MS on this. I can't even get them to tell me what this  "Aswebr Miniport"  or aswebr.sys file is all about. 

    You might want to wait on your re-install...I did that yesturday morning, and after the PC was updated by the Windows Update site the unknown devices reappeared! And this was before I installed any third programs/software.

    I re-formated the HD, put the PC back to fatcory defaults, got all the the available hardware updates from Dell then let Windows Upates do it's thing. After I got all the Windows updates the unknow device re-appearded.  Once I saw that, I used a system restore image and backups to return my PC to it's previuos state - before the re-instal rather than waisting more time re-installing all my software and files.

    There's got to be a Windows solution to this problem since the OS is apparently causing it.
