    Good morning!

    About an hour ago, I took the simplest option and disabled the service, so far, without any issues.

    I also have an old HP laptop and an old Dell Zino, the latter connected via HDMI to our TV. Both went from Win7 up to Win10 without any serious issues. Neither have the headline program/service "Monitor Virutal Wlan Service" running. Perhaps I should see how things unfold over the next few days, often checking the services to see whether "Monitor Virutal Wlan Service" might have been started by some other program.

    Thanks to Cliff S and Halasz for the suggestions. I will flag solved if all continues OK by the middle of the coming week.

    The Broadcom 811 wifi drivers do need virtual Wi-Fi to run (I know as I just added it manually to Windows PE) but it is a Microsoft service that exists anyway in Windows 10.

    If you look in the .inf file with notepad there is an "Include" in their .inf file to include an additional virtual adapter driver, like Intel have. When you open such a driver file, search for "Include=".

    In all latest Broadcom drivers (I'm using bcmwl63.inf), you'll see listed: "Include=netvwifibus.inf"

    To get Wifi to work you need only (I'm pretty sure), the driver, netwifibus, wlansvc (WLAN Autoconfig service), NativeWifiP, vwififlt and WdiWifi.

    Except for the actual driver all the other services are Microsoft and installed automatically in Windows 10 (but not in Windows PE - I was fighting to get Wi-Fi working there for days). Perhaps this service is a hangover from the past - who knows :)

    Appreciated but a tad technocal for this oldie!

    At which location and which .inf file is this referring to?

    Just checked device driver for Broadcomand there may be a problem:

    Attachment 45813
    most likely referring to the original pre-sale install of the operating system etc.

    As of now and after several reboots to check stability, everything seems fine.

    A quick check of the EVENT LOG shows a lot of Error occurences. For example:

    The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
    {D63B10C5-BB46-4990-A94F-E40B9D520160}
    and APPID
    {9CA88EE3-ACB7-47C8-AFC4-AB702511C276}
    to the user NT AUTHORITY\LOCAL SERVICE SID (S-1-5-19) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.


    in the Window's System log (along with many similar).

    Is there such a program that can be run to check the stability of a computer and its newish Windows 10 for any obvious errors/problems, missing problems, setting that are necessary or is that asking too much?

    Cheers and thanks

    Sorry about that. Bottom line is I don't think you have to worry. If all works with the service disabled leave it disabled.

    However to answer your questions...

    You have it in your third picture in post #5 but it is renamed from bcmwl63.inf to bcmwl63.inf.bak (for backup) for some reason. You can still look at it with notepad if you are interested.

    I can't see that picture but the message in event viewer is nothing to do with drivers. At the risk of going off on a tangent is because Local Service doesn't have authority to the RuntimeBroker. You can tell this by scanning in regedit for {9CA88EE3-ACB7-47C8-AFC4-AB702511C276}

    It is an old problem (not new to Windows 10) and happens on clean install with no third party drivers installed.

    I couldn't find a link but to fix it you can follow these steps. There is no real need to fix as it doesn't seem to cause any issue it but it makes the event viewer logs cleaner.

    Take ownership of this registry key HKEY_CLASSES_ROOT\AppID\{9CA88EE3-ACB7-47c8-AFC4-AB702511C276} as described in option 4 step 3 here

    Then go to control panel > administrative tools > component services.

    Browse to Computers > My computer > DCOM Configuration > RuntimeBroker and right click. Then select Properties > Security tab, edit Launch and activation permissions then add LOCAL SERVICE and tick Local Launch and Local Activation.

    Not really. This and that will help you with testing and fixing Windows corruption but will not help with drivers.

    There are 3rd party driver checking utilities but I'd recommend not using them. If it works, leave it :)

    Thank youhalasz. I am more timid than a hare when it comes to anything registry so I think I will give it a miss.

    I have run SFC several times in the past during my Win 7 life time that enabled the resident Seven Forum experts to provide help. I will give that a whirl during the week.

    Again, thanks for your generous help.

    Just an update, should anyone be interested.

    sfc /scannow

    has been run successfully. Nothing untoward to report and no repairs done.

    Thanks for your help.

    Good evening. I thought I should follow up the earlier SFC with another run.

    There were a number of problems but hopefully they are minor and most were fixed by the automated process.

    Should anyone feel the urge to have a gander at the CBS file, I have zipped it as an attachment to this post.

    Cheers, thanks and regards.

    That looks fine
    Code:
    [SR] Verify and Repair Transaction completed. All files and registry keys listed in this transaction  have been successfully repaired
    It is only if it says "Unable to repair" you have to worry :)
