How to Fix the Error 550

There are several kinds of errors you could encounter when you are running Windows 10 on a virtual machine. The Windows OS knows the difference between booting up in a standalone computer or in a virtual machine. This is why some specific drivers and system capabilities are used while emulating the Windows OS on software and during this phase, there are times when the System Preparation may throw up an error that says, “A fatal error occurred while trying to sysprep the machine”. This kind of error arises due to a race condition wherein the Sysprep command tries to stop the Microsoft Distributed Transaction Coordinator or MSDTC service and the VMware tool tries to start the MSDTC service. You may also see the following messages logged in the Setuperr.log file:

• [0x0f0082] SYSPRP LaunchDll:Failure occurred while executing ‘C:Windowssystem32msdtcprx.dll,SysPrepDtcCleanup’, returned error code -2146434815[gle=0x000000b7]
• [0x0f0070] SYSPRP RunExternalDlls:An error occurred while running registry sysprep DLLs, halting sysprep execution. dwRet = -2146434815[gle=0x000000b7]
• [0x0f00a8] SYSPRP WinMain:Hit failure while processing sysprep cleanup providers; hr = 0x80100101[gle=0x000000b7]

To fix the 0x0f0082, 0x0f0070, 0x0f00a8 Sysprep errors, you can check out two potential fixes. First, you have to check the status of the MSDTC service and the second one is to check the settings in the Windows Registry. Note that these fixes are proven to be effective on many users and apply to several versions of Windows, including Windows 10.

Option 1 – Check the status of the MSDTC service via Command Prompt

As mentioned, the error could be caused by the malfunctioning of the MSDTC service or it. Thus, you have to uninstall and reinstall the MSDTC service to resolve the problem and you can do that using Command Prompt. Follow the steps below.

• In the Start Search, type “command prompt” and from the results, right-click on Command Prompt and then select the “Run as administrator” option to open it with admin privileges.
• If a User Account Control or UAC prompt appears, just click on Yes to proceed.
• Once you’ve opened Command Prompt, execute this command: msdtc –uninstall
• The command you just entered will uninstall the MSDTC service. After that, you need to execute this second command to reinstall the service: msdtc –install
• Now exit Command Prompt and check if the error is now fixed.

Option 2 – Check the Registry settings

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and click OK or hit Enter to open the Registry Editor.
• After opening the Registry Editor, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSoftwareProtectionPlatform
• From there, look for a DWORD value that’s named “SkipRearm” and double click on it.
• Then change its value data to “1”.
• Restart your computer to apply successfully apply the changes made and check if it was able to fix the error.

Researchers have discovered 16 vulnerabilities in Bluetooth connections that could be exploited and make from minor to some serious damage to your device. The flaw can be used on chips manufactured by Intel, Qualcomm, and Texas Instruments while connecting to external devices like speakers, headphones, keyboards, mice, etc.

Who is affected?

Mentioned chips are used by many in a vast range of devices including big players with their products like Microsoft Surface laptops, Dell desktops, Samsung Phones, Google Pixel, and OnePlus handsets. The Bluetooth bug affects a wide range of devices, including smartphones, laptops as well as smart home gadgets. In total, more than one billion devices that rely on Bluetooth are believed to be impacted.

What is the damage?

The amount of damage possible with this flaw depends on the type of device with the chipset. Some devices can only be crashed after a specially crafted packet is sent to the flawed chip. If that's the case with your gadget, it can be easily resolved with a simple restart. With other devices, hackers can take advantage of the Bluetooth Classic flaw to remotely run malicious code. That could allow malware to be installed remotely. Researchers say vendors were informed about these issues months ago before the findings were published. The good news is this should have given plenty of time for the relevant patches to be pushed out that remedy the flaws. However, you'll need to make sure that you're running the latest version of the operating system to be protected by the patch crafted by the manufacturers.

Android Bluetooth threat

The researchers emphasize the lack of basic tests in Bluetooth certification to validate the security of Bluetooth Low Energy (BLE) devices. The BrakTooth family of vulnerabilities revisits and reasserts this issue in the case of the older, but yet heavily used Bluetooth classic (BR/EDR) protocol implementations. We would also advise users to disable Bluetooth on devices that do not need it. This way you can prevent attackers from sending you malformed LMP packets. Since BrakTooth is based on the Bluetooth Classic protocol, an adversary would have to be in the radio range of the target to execute the attacks. So, in a safe environment Bluetooth can be enabled.

Recently, a number of users reported that they were not able to run PLEX and other similar streaming services ever since a Windows Update was automatically installed in the system. The error in these streaming services has something to do with a missing Mfplat.dll DLL file from the Windows Media Feature Pack. On the other hand, some users also reported that the mfplat.dll error occurred on several games as well which used the Media Feature Pack. Usually, the mfplat.dll error is caused by the missing Media Feature Pack in Windows 10. Although most of the time the Media Feature Pack is installed by the application that needs it or through Windows Update automatically, there are just certain installers that do not have it. It could be that the Media Playback service was disabled by a particular Windows Update. Aside from that, the error might be because your computer is using Windows 10 N – a Windows 10 version that does not include the Media Feature Pack by default. Whatever the cause may be, you can troubleshoot the problem with the help of the options given below. But before you go on, keep in mind that downloading the missing DLL file and copying it to the folder of the program where you encounter the error won’t really help and will only make things even more complicated.

Option 1 – Install 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’ve determined that your computer 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 2 – 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 3 – Try extracting 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.

As you know, Diskpart is a useful utility that helps in managing the disks in a computer. It is a very useful tool that even when the GUI-based disk management tools in Windows 10 operating system fails, the Diskpart utility still tends to work. However, it also does not mean that this utility does not experience issues as it still does, from time to time. One of the issues you may encounter when using the Diskpart utility is when you encounter an error message that says, “DiskPart has encountered an error, Access is denied”. This kind of error in the Diskpart utility could be caused by a number of factors. For one, it could be that the Write-Protection is enabled on the drive where the operating is being performed or it could also be that the Command Prompt terminal does not have administrator-level permissions to carry out the command. Thus, you can try to run the Diskpart utility again but this time with admin privileges or you could also remote the Write-Protection from the concerned drive. For more details, refer to the instructions given below.

Option 1 – Try running Command Prompt with Administrator-level permissions

• In the Start Search, type “command prompt” and from the search results that appear, look for Command Prompt.
• Once you found it, right-click on it and select the “Run as administrator” option.
• After that, try to execute the Diskpart operation once again and see if you still encounter the same error.

Option 2 – Try to remove the Write Protection from the drive

As mentioned, removing the Write-Protection on the concerned drive could also help you fix the problem and there are two ways to get rid of the write protection – you can either use the Diskpart utility or the Registry Editor. How? Refer to the following steps.

Via Diskpart utility:

• Open Command Prompt with admin privileges and then type the “diskpart” command and tap Enter to execute it.
• Next, type “list disk” and tap Enter to get the list of all the Disk connects or all the partitions that are formed on those disks.
• After that, you need to choose one command depending on the list of commands you entered. Type “select disk #” and tap Enter to select the disk or partition you want to select.
• Then type “attribute disk clear readonly” and tap Enter to Disable the Write Protection on the selected disk or partition.

Via Registry Editor:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to the following registry key:

ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorageDevicePolicies

• After that, look for the DWORD named “WriteProtect” and double click on it, and then set its Value Data to “0”.
• Now restart your computer and see if the problem is now fixed or not.

Microsoft starting as of today will block its Office 365 users if they are using Internet Explorer or early versions of Edge browsers. So if you are using older non Chromium Edge versions of Microsoft browsers you can no longer access Office services until you switch. Now normally I would fully support this kind of decision since Internet explorer is a slow and vulnerable browser and the edge is similar in that regard. The new edge browser is great and it should be used but the issue I have is that Office 365 is not free, it is a premium feature and I am wondering how Microsoft plans to deal with people that have already paid for service but suddenly cannot access it anymore.

Error Code 0x80073afc - What is it?

Error code 0x80073afc deals with an antivirus program first built into Windows 8/8.1 This error occurs when Windows Defender, the built-in anti-virus software in Windows 8/8.1 and higher, does not start automatically and users attempt to manually start the program. During the initialization period of the program start-up, something goes wrong and users get a 0x80073afc Error message. The error message states there was a problem with the initialization of the program. Windows Defender provides protection of your computer and it is advised by the Microsoft Corporation that you ensure it starts up automatically on every start-up.

Solution

Further Information and Manual Repair

Users have found several manual repairs that have fixed the problem without needing to contact technicians for extra help. While the methods below should solve your problem easily, if this is the first time you have encountered the issue you may want to do a simple restart. This has fixed the problem for some users and is the easiest first troubleshooting move. If it doesn’t work move on to the methods listed below, which are easily completed without extra help.

Before trying any of these methods, please make sure that you are logged into a profile that is listed as the administrator of the computer of his administrative powers enabled. If this is not the case you will not be able to complete the following methods. Please log out and log back in on the administrator profile.

Method 1:

First, check to see if you have a third-party anti-virus program installed on your computer. Some users believe that the built-in Windows Defender program is not powerful enough to handle the safety of their computer so they usually download a third-party program. However, that program may have caused a conflict with Windows Defender and may not allow it to open. If you do have a third-party program installed, try uninstalling it then manually starting Windows Defender.

Method 2:

If method one does not work, you may be infected by malware or a virus that has tampered with the settings on your computer and will not allow Windows Defender to start automatically or manually.

First, open Run by holding the “Win” key and pressing the “R” key. Then type “Regedit”. The program will ask for permission to follow through with this action. Click on “Yes” and the Open Registry Editor will open.

Find the HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionImage File Execution Option and check to see if there are any files similar to MSASCui.exe or MpCmdRun.exe. If there are any file entries that resemble that, you will want to right-click on them before selecting the “Delete” option. If you do not see any entries that match, this is not the issue with your Windows Defender and you will want to try another method.

The Registry on your computer is very important. It helps tell your computer what programs are safe to run, what programs should be run, and what programs should not be run. If it is tampered with by a virus or Malware, multiple system operations can be affected.

However, if you did find similar file names, and you deleted them, try to start Windows Defender manually. If it does not work again, move on to the next method. 

Method 3:

If the first two methods do not work for your issue, and you are still receiving error code 0x80073afc when attempting to start Windows Defender, this step should solve the problem if you have Restore Point installed on your computer, which you most likely do.

For this method, we will be restoring your computer to a previous Restore Point. First, just like in method two, hold the “Win” key and press the “R” key. This will open run.
