Option 3 – Try to reinstall the Intel Driver and Support Assistant

If the Intel Driver and Support Assistant is corrupted, you need to uninstall it from your computer.

How to Add Safe Mode to Windows 10 Boot Menu Options
In any Windows operating system, Safe Mode is definitely a special environment used for troubleshooting issues as well as system diagnostics. Safe Mode allows you to remove any malware in your computer and troubleshoot issues that can’t be fixed when you’re in desktop mode. This is why Microsoft made sure that the Safe Mode option is not available directly and can only be accessed by pressing function keys such as F2, F8 (depends on what PC you are using) or via MSConfig. To make it easier for you to access Safe Mode, this post will guide you on how you can add Safe Mode to the Boot Menu options in Windows 10. As you know, Windows 10 now has Advanced Startup options that allow you to boot directly into Safe Mode without having to restart your PC and then tapping the special key a couple of times. However, if you really have to always use Safe Mode, it’s best to add it in the Boot Menu options. To do that, simply follow the steps below.
  • Select Command Prompt (Admin) option from the WinX menu to open Command Prompt with administrator privileges.
  • After opening Command Prompt, type the bcdedit /copy {current} /d "Safe Mode" command and hit Enter.
  • Once the command is executed, you will see a message saying, “The entry was successfully copied to {74a93982-9486-11e8-99df-00270e0f0e59}”. This message indicates that Safe Mode was successfully added in the Boot menu option which means that you can now directly access it and boot your Windows 10 PC in that mode.
To check if Safe Mode was really added in the Boot menu options, you have to open Msconfig. From there, you will also have to use it to configure the boot settings for the Safe Mode entry. To do so, follow the given steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “MSConfig” in the field and click OK.
  • Next, go to the Boot tab and find the Safe Mode option which should be located under the default Windows 10 mode.
  • Afterward, you need to select the Sage boot option and Minimal. You also have to select the Make all boot settings permanent option.
  • Make sure to increase the timeout to at least 10 seconds which will ensure that the menu does not disappear right away.
Note: In similar steps as above, you can add the Safe Mode with Networking and Safe Mode with Command Prompt entries as well. Just simply select “Network” for Safe Mode with Networking and “Alternate Shell” for Safe Mode with Command Prompt. Once you’re done adding any of them, click on Apply and restart your PC. In addition, if you wish to remove the entry, you just have to open MSConfig again and select the entry you want to remove, and then click Delete.

How to Fix Error Code 0x80073afc

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

Restoro box imageFurther 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. 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.
