Fix: Error Code 0x800704ec when Turning On Windows Defender

There have been a lot of cases where the users are experiencing errors related to the Windows Defender in their Windows 10 Operating System and no matter what they do or how many times they try to reboot their computer, this error shows up and they are not able to ultimately turn on the Windows Defender. The error code 0x800704ec appears in the form of notification by your Windows computer.

The Windows Defender icon will turn into a different color to indicate that it is unable to start and will pop up an error on your face. All the Windows Operating Systems are vulnerable to this problem and they can pop this error up either when you click on the icon of the Windows Defender or when you try to turn on the Windows Defender. One of the simplest reasons is when your third-party antivirus software is messing around or creating a conflict with the Windows Defender program. Some of the examples of those antiviruses are Avast, Comodo, Bitdefender, and many more. This so-called Windows Defender used to be an optional download for the previous old windows versions but is now available for the Windows 8, Windows 8.1, Windows 7, Windows 10 as well as the Windows Vista version. When it was released in the 8.x versions, this Windows Defender turned into a full-time antivirus software which was responsible for the Real-Time protection of the Windows systems.

Once the users decide to install the third party antivirus software, the Windows Defender software will automatically switch itself off so as to prevent conflicts between the new antivirus software that the user installed and the Windows Defender program which exists by default. In case you recently installed any other antivirus program or just activated it for experimental purposes, make sure you disable the third-party security software and use the Windows Defender software without facing the Error Code 0x800704ec issue.
