It may occur at times that Windows Defender either goes unresponsive or it shows you a warning screen with the message-“This program is blocked by group policy. For more information contact your system administrator. (Error Code: 0x800704ec)”, commonly called as Windows Defender error code 0X800704EC

I understand this and so here I am with Windows Defender error code 0X800704EC Solution.
I provided several solutions and alternatives as well. That should easily eradicate your problem.
What is this 0X800704EC error code?
You cannot consider this error as your software or Memory related glitch. It mainly occurs due to corrupt or broken Registry files.
So, this error has broad prospects!
And here I will take up the unresponsiveness of Windows Defender.
Because security is something with which you can never compromise.

And never consider Windows Defender error code 0x800704ec will limit itself to Windows Defender PC. Since it is a Registry based error, it will harm your Windows PC in other ways like slowing it down, shutting down unexpectedly, crashing etc.
Why this error occurs?
One of the general reasons I found is when you run two anti-viruses simultaneously on your Windows PC.
When I tried running Avast and Windows Defender together, Windows Defender error code 0X800704EC popped up.
But it varies considerably. You can see this error at times when you download updates for Windows Defender and install them.
The next moment you try to open it up, the error comes again.
So, what I found was there are following reasons as to why this error occurs-
- Lack of proper sync between your Windows Defender Updates and Windows 7/8/8.1/10 PC.
- Virus or malware attacks.
- Broken Registry entries or expired even.
There are times when incorrect entries of Windows Registry may result in this error.
- Wrongly configured Windows system files.
- PC memory unable to handle Windows updates or in simple words, memory is not enough or not properly defragmented.
And of course, installing infectious apps and software!
But there can be more because Registry errors are something which can cause multiple problems. And they may not be even inter-connected.

Fix Windows Defender error code 0x800704ec- Process I
I shall start by giving you the simplest of all processes.
I mentioned above that running two or more antiviruses simultaneously on your system may result in this error code.
So, in this method, I would tell you steps to uninstall all another antivirus (es) running parallel to your Windows Defender on PC.
- From your Start Button / Windows button, open up Control Panel.
- Go to Programs and Features.
- You will find a program mentioned as an antivirus
As an example, I am uninstalling my Avast antivirus.
- Just press the Uninstall button
There may be circumstances when the antivirus won’t uninstall from the Control Panel. So here is an alternative method for you.
- On Windows Run, enter the following “appwiz.cpl” and click on Run.
- Search for your specific antivirus program running on your Windows PC along with Windows Defender.
- You will see an Uninstall Button. Click on it.
- If you are prompted with additional dialog boxes, agree to all those and completely uninstall.
- Either there will be another system prompt asking you to restart your PC or you can manually do it from the Power button or the start button.
This should remove all other antiviruses from your Windows 7/8/8.1/10 PC.
When this done-
- Navigate to Control Panel once again.
- Find the Windows Defender option.
- Check if it is enabled and ON. If not, do it manually.
If the above basic uninstallation method doesn’t eliminate the Windows Defender error code 0X800740EC issue, here is the next method for you.
