Feel free to use any provided method as both works (except on Windows 10 Home edition) and achieve the same thing, it all comes down to preferred preference on how you wish to do things.
This method is more straightforward and easier perhaps than its counterpart but it has one significant drawback, it will not work on Windows 10 Home edition which does not have in itself a policy editor included. If you are using Windows 10 Home edition then feel free to skip this method and do it via registry editor. That being said let's start:
The registry editor method is a more complex one but it will be your only way of doing it if as mentioned you are running Windows 10 Home edition. As always it is highly recommended to make a backup of the Windows registry before tempering with it.
note: you can always change values back in order to show again panel by changing the value to 0 in registry editor or choosing Not Configured or Disabled in the local group policy editor

The Error Code 0x802400d most often occurs when users attempt to use the Windows Update tool on their computers to move from one version of the software to another.

While it can take additional time to deal with the issues that cause Error Code 0x802400d to appear on your computer, there are several steps that you can take to address the problem. These are fairly simple to perform and do not require advanced knowledge of the system to employ.
Error CausesThe most basic cause for Error Code 0x802400d is that there is a file or a process that is causing the update process to hiccup. In many cases, this error appears when a user attempts to begin the process of updating their computer if they have several stacked updates to perform. Computers that are several updates behind where they should be will display this error more often than computers that are kept on a schedule of recommended updates.
While there are multiple reasons why the Error Code 0x802400d may appear on your computer during the Windows Update process, there are several methods that can be used to attempt to resolve the problem on your own. These are generally easy to do and do not require advanced techniques. However, if you do not feel comfortable addressing the issue on your own, contact a qualified Windows repair technician.
Here are some of the best methods that users can employ to resolve Error Code 0x802400d:
There are a number of different processes, files, and settings that could cause Error Code 0x802400d to appear on your computer during the Windows 10 Update process. For this reason, the most efficient way to determine what the culprit is for your specific issue is to download and use the System Update Readiness function.
This tool is available directly from Windows. Although there are other tools available on the Internet that claim to be able to fix the problem, these can contain viruses and malware, so be cautious if you decide to employ these instead. There are also several versions of the tool on the Windows website, so be sure to download the version that matches the operating system and version of your computer.
Once you have downloaded the Readiness tool from the Windows website, allow it to run a scan on your system. At a minimum, this process will take about fifteen minutes to complete. Although you will see a progress bar at the bottom of the window, it does not always update effectively. Some users have reported that the update appears to stop when it is two-thirds complete. Continue to let the scan run if this happens, rather than canceling it out. Even if the progress bar doesn’t update, the scan is still running.
If you have recently installed new software on your machine, it can sometimes cause problems with the update process. The best way to resolve this issue is to remove or uninstall the software, run the update process again, and then reinstall the software once the Windows system has been successfully updated.
If the above methods are not successful in resolving Error Code 0x802400d from your machine and you are still unable to complete the Windows 10 Update process or if you are not confident in your ability to complete these steps successfully on your own, get in touch with a qualified computer repair technician who is familiar with the issues surrounding Windows 10 in particular.

“SYSTEM [DRIVER] USB AUDIO DEVICE An audio stream is currently in use [DRIVER] Legacy Kernel Caller.”Step 2: The next thing you have to do is remove all the external hardware connected to your computer. In this step, you have to disconnect external hardware from your computer. Based on reports from users who experienced the same issue, the “TV card” is the culprit so make sure you remove that one. Once you’ve removed it, open Command Prompt and run the “powercfg –requests” command again and you’ll see that the “Legacy Kernel Caller” will no longer be on the list. In addition, your computer will get into its regular sleep mode once the hardware is removed. Once you do that, the driver gets hung and won’t release the power request despite being used. Step 3: Try using the request override option The powercfg command also offers a request override option which allows users to disable the requests from applications and services to wake the computer from sleep mode. To run this command, simply open Command Prompt with admin privileges. After you open Command Prompt, type the following command and hit Enter to disable requests from applications and services that causes the computer to wake from sleep state.
Powercfg -requestsoverride Driver "Legacy Kernel Caller" SystemStep 4: Check the streaming and media applications You also have to check if your computer is running an audio or video service in the background. In such cases, your computer won’t be able to go to sleep mode if these services are running in the background. You might have noticed that when you play a video or audio, your computer never goes to sleep. And if you have put it to sleep in between watching the video, then it’s probably why your computer is waking up. Thus, you have to stop these services. Step 5: Check the devices that can wake your computer If you didn’t see the Legacy Kernel Caller in the result after you execute the ”powercfg –requests” command, then you can try to execute the following command instead.
powercfg –devicequery wake_armedAfter you enter this command, it will give you a list of all the devices that can wake your computer. So if there is anything other than the mouse, keyboard, touchpad, you have to check the power configuration of that device. To do that, go to the Device Manager and disable the device’s “Allow this device to wake the computer” option in its Properties Step 6: Check the Sleep Advanced Settings
