    Device manager fails to open with error 0xc0000043


    Device manager fails to open with error 0xc0000043. Win 64 Pro. Have done the usual DISM and sfc /scannow and no change. Have also tried reimage and no luck. PC is a Lenovo ThinkCentre. Discovered the error when I tried to open Device Manager to see why a smart USB stick wasn't found. Problem still occurs when all external USB devices are disconnected from the PC.

    How do I fix this error?

    Thank you,

    John

    Device Manager Un-Hiding Hidden Devices


    When you connect a plug and play device, Windows Plug and Play manager detects it, finds and installs the driver. Device Manager lists the device with a solid icon.

    The driver is only removed when you uninstall the device, not simply by disconnecting the device. When the device is disconnected, its driver is still installed. By default, Device Manager only displays connected devices. When you show hidden devices, note the Bluetooth icon you see is semi-transparent (not opaque). That indicates a "non-present" device. Sometimes also called a "ghost" device. The driver is still installed but the device is not currently detected (i.e. not connected).

    Device can be disconnected when
    • Device unplugged (e.g. removing a USB device)
    • Turning a device OFF
    • Disabling the device in BIOS (then windows won't detect it) or
    • Device failure

    So
    • Check BIOS as suggested
    • Check board connections
    • Can b/t be turned off by a switch? or keyboard combination?
    Also possible the b/t h/w failed

    Device manager fails to open with error 0xc0000043

    Error: No work available to process

    Hmm. Either it's put out errors and WCG is limiting the work units available, or the project list may not be set to supply other WU when one runs out. (if the problem lies here and not on your end)

    On the options to your left, if you go into Results Status, select the computer from Device Name and then look through results see if either they were returned late, errors or any other kind of issue that would stop the servers supplying WU from that perspective.

    If there are no errors then it's maybe down to your project list. So selecting Device Manager from the left menu and then clicking on the profile assigned to that computer and make sure that it's assigned to receive WU for other projects if they run out.

    At least those steps will rule out problems from the WCG end.
