This post will guide you in fixing a particular problem where your Windows 10 computer does not even let you turn it on and it appears as soon as it starts to boot the operating system and it displays an error message that says, “The Boot Configuration Data for your PC is missing or contains errors, Error code 0xc0000185”. On the other hand, it may also display a different error message saying, “The operating system couldn’t be loaded because a required file is missing or contains errors”.
There are various suggestions you can try to resolve this error. You could check the physical status of your hardware or rebuild the Boot Configuration Data, use the Automatic Startup Repair or System Restore, or better yet, reset your Windows 10 computer.
Since your computer will not boot, you will have to either try to get into the Advanced Startup Options screen, boot Windows 10 in Safe Mode, or use a bootable Windows 10 media to boot your computer.
The first thing you can do to resolve the issue is to Rebuild Boot Configuration Data or BCD files.
In this option, you need to boot your computer into the Advanced Startup Options and from there, run the Automatic Startup Repair and then wait until the process is completed.
Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.
You should also check the physical status of the hardware in your computer. You can clean the dust off the hardware components like the Network Card of the computer. You might want to use a small blower or you could also use a soft cloth and run the components gently. Make sure that you don’t damage any parts with moisture or cause harm to any circuits while you carry out this task.
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.
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.
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.
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.
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. Next type “Rstrui.exe” and click “ok”. After some time, you will see System Restore Windows. Click “Next” and select the restore point that you would like to go back to. After your computer has restored to the point you selected, check to ensure that Windows Defender has started correctly.
If the above methods aren't able to rectify the issue, you might have to download and install a powerful automated tool to get the job done.
