    Can not open Device Manager


    Hi Everyone:


    I have upgraded my Windows version to 2004OS Build 1904.1 and since then I can not open the device manager from within the control panel and windows shows a dialog box with this content :

    User Account Control

    This App. has been blocked for your protection.

    An administrator has blocked you from running this app. For more information contact Administrator.

    MMC.EXE


    Publisher: Unknown

    File Origin: Hard Drive on this computer

    Program Location" C:\Windows\system32\mmc.exe" C:\Windows\sysytem32\devmgmt.msc


    I changed the permission settings for that file but didn't work. So, Could you tell me how I can get the Device Manger running normal again.


    Thank you;


    Reza Niazi

    :)

    USB microphone show up under "Other Devices" in the Device Manager

    Hi Luke,

    We suggest that you update the device driver. You can do that by following these steps:


    • Select the Start button, type Device Manager, and select
      it from the list of results.

    • Expand the category where your device is located, then right-click on the name of your device, and select Update Driver Software.

    • Select Search automatically for updated driver software.

    If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions.

    If updating the device driver doesn't work, we suggest that you reinstall the driver:


    • Open Device Manager.

    • Right-click on the name of the device.

    • Select Uninstall.

    • Restart your PC and Windows will attempt to reinstall the driver.

    Let us know how it goes.

    Regards.

    Hi,

    Since you mentioned that the said driver is missing in Device Manager, what we suggest is for you to check in the Hidden Devices section on Device Manager. Kindly follow the steps below:

      Device Manager.
    • Click on View and select
      Show Hidden Devices.
    • Check for the webcam under Imaging Devices.
    • If the webcam is listed, then right-click on it and select
      Update Driver Software
    • Select Browse My Computer for Driver Software and follow the prompted steps.
