Error Code 45 is quite a common error people see in the Device Manager. This error occurs when Windows fails to recognize the hardware device connected to the system, throwing up the following message on your screen:
This hardware device is not connected to the computer Code 45
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, says Microsoft.
But at times this Device Manager Error Code may continue to plague you. Your system may crash when you attempt to use the hardware device for which this error had previously appeared. Moreover, your Windows may run slowly or hang up frequently.
