Fix Error 0x80200056 during Windows Update

If you are familiar with the Dynamic Lock feature in Windows 10, then it has probably made it easier for you to lock your computer the instant you move away from it. This interesting feature does not need any special software like IR Cameras to use this feature as long as your Windows 10 computer supports Bluetooth which it most likely does. However there are times when the Dynamic lock feature is either missing or not working. When that happens, here are some suggestions that could help you. But before anything else, you need to create a System Restore point first since you will be modifying some critical system settings as well as registry files. After you’ve created a System Restore point, refer to the following options below to fix the issue with Dynamic Lock.

On the other hand, if you disable or don’t configure this setting, you can continue locking your computer with existing locking options. Take note that it may be Not configured or Enabled but shouldn’t be set to Disabled.
• Now select the radio button for Enabled and set the Signal rules then click OK.
• Then exit the Group Policy Editor and restart your computer.

Interrupts are designed so that the resource requests don’t get into a headlock when it comes to the hardware level. To simply put it, it is used to break a loop that never ends. Aside from that, developers also designed levels in order to prioritize interrupts. It is also known as “Interrupt Request Level” or IRQL. And if you suddenly encounter a “Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL” error, this means that a driver has accessed a memory location illegally while NT is operating at a specific IRQL. The Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL is a fatal driver coding error and as an end-user, there isn’t much that you can do to resolve it but if you’re a developer, then this means that your code is trying to access an invalid memory location. You could check on different parameters such as memory location that was referenced and code addressed which referenced memory. The technical parameters are:

• a memory location that was referenced
• IRQL at time of reference
• 0 = read, 1 = write
• code addressed which referenced memory

As mentioned earlier, if you are an end-user, there is nothing much that you can do to resolve this problem, but worry not for there are still possible solutions that could help you in fixing it. Refer to the suggestions laid out below to fix Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL error.

Option 1 – Try running the Hardware and Devices Troubleshooter

The first thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem. To use it, refer to these steps:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 2 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Run the Memory Diagnostic Tool to check for Memory leaks

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer

If you are using a Windows 10 PC that has different processors clubbed together, chances are you might encounter an error saying, “MULTIPROCESSOR CONFIGURATION NOT SUPPORTED” during a Windows upgrade or software installation. This error is actually caused by a bug check with a value of 0x0000003E. This error also indicates that the processors in your computer are asymmetric in relation to one another. So if you want to upgrade you need to have all the processors of the same type and level. But worry not for this guide will help you in fixing this error. The MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED error can occur in several cases such as during an installation of Windows 10, or when the driver is loaded, or when Windows Start or Shutdown and the chances of you getting a blue screen is very much high. To fix this error, refer to the options given below and make sure to follow them carefully.

Option 1 – Try to disable the Hyper-Threading in your BIOS

Hyper-Threading in the BIOS lets a processor (multi-threaded) run various tasks in a simultaneous manner. To disable this, here’s what you have to do:

• Restart your computer and boot into it right after. To do that, tap the F2 key.
• Once you’re in the BIOS, locate the Hyper-Threading option which should be located under the Performance section along with other options like Multi-core support, Rapid Start technology, and many more.
• Disable Hyper-Threading and then make sure to save the changes and exit BIOS.

Note: Although Hyper-Threading is only used when necessary, there are some OEMS that don’t have the option to disable it and if that’s the case, you need to try other options given below.

Option 2 – Try to disable the Virtualization in the BIOS

Virtualization in the BIOS allows users to run a single physical resource such as the server or storage device to appear that it is running as multiple logical resources. It is also properly termed as “HYPER-V”.  To disable it, refer to these steps:

• Boot into the BIOS as you did earlier.
• Then look for the Security options.
• After that, from Security options, look for Virtualization Technology or VTX among the options given.
• Then turn it off and restart your computer.

Note: Although Windows 10 offers features such as the Device Security for Core Isolation and Memory Integrity, if you turn them off at the software level, it will not help at all. If you’re able to resolve the error, you can do some further research and see what software or hardware you can use to further help you.

Option 3 – Try checking if there are any BIOS updates available for your PC

Updating the BIOS may help you resolve the MULTIPROCESSOR CONFIGURATION NOT SUPPORTED error. You can just go to the OEM’s website as they offer utility software that can download BIOS firmware and update it without any problem. BIOS updates usually offer enhancements and fixes to some issues like this one.

Error code 0Xc004F074 - What is it?

Did you previously use Windows 7 or 8 but decided to run with the latest Windows 0S, Windows 10? An early error message encountered was activation error code 0Xc004F074. Error code 0Xc004F074 is manifested when the user fails to activate Windows directly after the installation of Windows 10. This occurs if the previous operating system on your computer was Key Management Service (KMS) activated.

The KMT provides a more seamless operation when users are activating volume license editions of Microsoft Windows and Office. This process tends to be clear to end-users of the system.

Symptoms of error code 0Xc004F074 include:

• Windows is unable to reach your company’s activation service.
• The Key Management Service is unavailable.

Solution

Error Causes

Various factors might incite error code 0Xc004F074. A primary cause is a discrepancy or difference between the KMS client and the KMS host machine. The host computer could possibly be operating a Windows Server 2003 or Windows Server 2008, while the client runs on OS Windows 7 or Windows Server 2008 R2. To supplement, the computer’s time might be a contributing factor. The time on the host machine and client might show a difference (Usually the host time exceeds 4 hours).

Further Information and Manual Repair

To rectify error code 0Xc004F074, users are advised to try various methods. These methods include:

1. Method 1: Update Your KMS Host 9 (Windows Server 2003)

Are you running later versions of Windows Server? Use an update that fixes or installs KMS on your computer. The update is available on Microsoft’s website. Keep clearly in mind that the update is only for Windows Server 2013 Service Pack 1 and later versions of Windows Server 2003.

2. Method 2: Update Your KMS Host 9 (Windows Server 2008)

This step is similar to the aforementioned. However, it applies to Windows Vista and Windows Server 2008. This ensures the service is extended to Windows 7 and Windows Server 2008 R2.

3. Method 3: Update the Time

It was previously mentioned that the time reflected on the KMS host and client might cause error code 0Xc004F074 to manifest. A simple fix to adhere to is to always ensure that the time between both is updated. To Resync the time on the client, execute the following command.

w32tm /resync

4. Method 4: Uninstall the Existing KMS

For this method to be successfully deployed, you’ll need to have in your possession an activation key or KMSpico Key. As you cannot apply the new key with the existing one, remove or uninstall the initial key. To perform this step, open the command prompt. This should be done while the computer is in admin mode. Then, run the command

(slmgr.vbs /dlv)

It should be executed without the brackets and before you have removed the existing key.

After executing the command, you’ll encounter the description:

Windows(R) Operating System, VOLUME_KMS_WS12_R2 channel

Move along with the process by applying the slmgr.vbs /upk to uninstall the existing KMS key.

After the old key is uninstalled, you’re ready to apply the following:

slmgr.vbs /ipk <NewKMSProductKey>

To check if things are in place and complete the process, follow the steps below: PC Settings >Update and Security > Activation

5. Method 5: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

One of the primary packages that install the Windows Media Player is the Media Feature Pack among other related files that are needed by the associated software products. And one of the essential DLL files in that package is the mfplat.dll file which is needed by various games and streaming services. So if this DLL file goes missing, you will most likely encounter any of the following error messages:

• “mfplat.dll missing”
• “The application failed to start because mfplat.dll was not found.”
• “The program can’t start because mfplat.dll is missing from your computer.”

In other circumstances, the Media Feature Package does not come pre-installed with the main Windows package especially for those who use Windows N, thereby causing the error to pop up. The main cause of this problem is that users who use Windows 10 N do not have the Media Feature pack pre-installed with the installation package. Aside from that, the installation package could go missing after a few Windows Updates or if you have uninstalled it by accident. To resolve this problem, you need to check out each one of the given options below.

Option 1 – Try to enable Media Playback via Command Prompt

If you encounter the mfplat.dll missing error when you attempt to run PLEX or other similar streaming service and you’ve already verified that the Media Feature Pack is indeed installed, you might want to try enabling it using an elevated Command Prompt. There are cases when a particular Windows Update ends up disabling the feature and creates the grounds which results in the mfplat.dll missing error. Thus, you can have to enable the feature via Command Prompt.

• Tap the Win + R keys to open the Run dialog box.
• Then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• Next, click on Yes if a User Account Control prompt pops up.
• After opening Command Prompt, copy and paste the following command and hit Enter to execute it:

dism /online /enable-feature /featurename:MediaPlayback

• Close Command Prompt and then open the app once again to check if the problem is now fixed.

Option 2 – Try installing the Media Feature Pack for Windows 10 N version

As mentioned, the Windows 10 N version does not come with Windows Media Player. Meaning to say, the Media Feature Pack is also not installed by default or won’t be updated by the Windows Update component. So if you are not quite sure what Windows 10 version you currently have installed, refer to these steps:

• Tap the Windows key + S and then type “about” in the search box.
• From the search results, click on the “About your PC” to open the About tab of the Settings app.
• Afterward, scroll down to the Windows specifications and check your Windows version under Edition.

Note: If you have verified that your PC is using the Windows 10 N version, you need to install the appropriate Media Feature Pack for your computer. How? Refer to the steps below:

• Click this link to download and install the Media Feature Pack from Microsoft’s official website.
• Upon installation, select the edition you want to install using the drop-down menu and then click on Confirm. Take note that there are few reasons why you’d want to install the older version since most streaming services like PLEX and most games usually require version 1803.
• After that, wait until the request is validated. The download should begin in a few minutes automatically.
• Once the download is completed, open the installation executable file and follow the next on-screen instructions to install the Media Feature Pack on your computer.
• Restart your computer. After your computer has rebooted, open the application where you’re getting the mfplat.dll missing error and then check if the problem is now fixed.

Option 3 – Try to extract a copy of the mfplat.dll file from the windows.old directory

If you encounter the error shortly after you just upgraded to Windows 10 from an older version, the best thing you can do to resolve the problem is to use windows.old directory to fetch an old copy of the mfplat.dll file. To do so, follow the steps below.

• Go to the Windows drive and then look for the windows.old directory where it preserves a copy of your old operating system as well as associated files in case something goes out of hand during the upgrade process.
• After that, open the windows.old folder and then go to the syswow64 folder.
• Next, from the syswow64 folder, copy the mfplat.dll file and paste it to C:/windows/syswow64.
• Restart your computer and check if the error is now resolved or not.
