Recommended resolution
This problem occurs if you install a driver for a non-Plug and Play device, but Windows cannot find the device. Here are some things that you can try to resolve this problem.

If the Troubleshooting Wizard does not resolve the problem, do one of the following:
  • If the device was removed, uninstall the driver, connect the device, and then click Scan for hardware changes to reinstall the driver.
  • If the hardware was not removed, the driver files might be obsolete. In this case, update the driver from Device Manager. In the device Properties dialog box, click the Driver tab, and then click Update Driver to start the Hardware Update Wizard. Follow the instructions to update the driver.
  • If the device is a non-Plug and Play device, you may have to install a newer version of the driver. To install non-Plug and Play devices, use the Add Hardware wizard. Click Start, and then click Run. In the Open box, type hdwwiz.cpl.

Code 42

Windows cannot load the device driver for this hardware because there is a duplicate device already running in the system. (Code 42)
Recommended resolution
A duplicate device was detected. This error occurs when a bus driver incorrectly creates two identically named sub-processes (known as a bus driver error), or when a device with a serial number is discovered in a new location before it is removed from the old location. You may be able to resolve this problem by restarting your computer.

Restart your computer

Click Start, click Shut Down, and then select Restart in the Shut Down Windows dialog box to restart the computer.

Code 43

Windows has stopped this device because it has reported problems. (Code 43)
Recommended resolution
One of the drivers controlling the device notified the operating system that the device failed in some manner.

If you have already run the Troubleshooting Wizard, you might want to check the hardware documentation for more information about diagnosing the problem.

Code 44

An application or service has shut down this hardware device. (Code 44)
Recommended resolution
Restart your computer

Click Start, click Shut Down, and then select Restart in the Shut Down Windows dialog box to restart the computer.

Code 45

Currently, this hardware device is not connected to the computer. (Code 45)
Recommended resolution
This error occurs if a device that was previously connected to the computer is no longer connected. To resolve this problem, reconnect this hardware device to the computer.

No resolution is necessary. This error code is only used to indicate the disconnected status of the device and does not require you to resolve it. The error code resolves automatically when you connect the associated device to the computer.

Additional information

If Device Manager is started with the environment variable
DEVMGR_SHOW_NONPRESENT_DEVICES
set to 1 (which means show these devices), any previously attached (NONPRESENT) devices are displayed in the device list and assigned this error code.

Code 46

Windows cannot gain access to this hardware device because the operating system is in the process of shutting down. (Code 46)
Recommended resolution
The device is not available because the system is shutting down.

No resolution is necessary. The hardware device should work correctly next time that you start the computer.

This error code is only set when Driver Verifier is enabled and all applications have already been shut down.

Code 47

Windows cannot use this hardware device because it has been prepared for safe removal, but it has not been removed from the computer. (Code 47)
Recommended resolutions
Reconnect the device

This error code occurs only if you used the Safe Removal application to prepare the device for removal, or pressed a physical eject button.

Reconnect the device to your computer

Restart your computer

Make sure that the device is connected correctly to your computer, and then restart your computer. Click Start, click Shut Down, and then select Restart in the Shut Down Windows dialog box to restart the computer.

Code 48

The software for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)
Recommended resolution
Update the driver

Contact the manufacturer of your hardware device to obtain the latest version or the updated driver. Then, install it on your computer.

Code 49

Windows cannot start new hardware devices because the system hive is too large (exceeds the Registry Size Limit). (Code 49)
Cause
The system hive has exceeded its maximum size and new devices cannot work until the size is reduced. The system hive is a permanent part of the registry associated with a set of files that contains information related to the configuration of the computer on which the operating system is installed. Configured items include applications, user preferences, devices, and so on. The problem might be specific devices that are no longer attached to the computer but are still listed in the system hive.
Recommended resolution
Uninstall devices that you are no longer using

To resolve this problem, you should first try uninstalling any hardware devices that you are no longer using.
  1. Set up Device Manager to show devices that are no longer connected to the computer.
    1. Click Start, and then click Run.
    2. In the Open box, type cmd. The Command Prompt window opens.
    3. At the prompt, type the following command, and then press Enter:
      set devmgr_show_nonpresent_devices=1
  2. In Device Manager, click View, and then click Show hidden devices. You will now be able to see devices that are not connected to the computer.
