Windows defender couldnt be enable after being disabled

Hello Imtiaz,

Thank you for posting the query on Microsoft Community.

I appreciate your interest on Windows 10.

Before we proceed I would like you to answer the following questions:

• 
  Have you installed any third-party security software on your computer?
  
• 
  Are you using administrator account?
  
• 
  Is the computer connected to domain?
  
• 
  Did you try restarting the computer and check?
  

I suggest you to follow the methods below:

Method 1

update the group policy and check.

• 
  Press Windows key + R.
  
• 
  Type Gpupdate and press enter.
  
• 
  Then try enabling the Windows defender in group policy and check.
  

This issue usually arises when you have installed a security software on your computer. From Windows 8 onwards, the Windows Defender is equipped with all the functionalities of an anti-virus software including real-time protection which was not
present in Windows Defender in Windows 7.

Method 2

If you have any third-party security software installed, I would suggest you to uninstall thatsoftware and then upgrade to Windows 10. As it is not recommended to keep more than 1 anti-virus software with real-time protection.

Important Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable/uninstall your antivirus software. If you have to temporarily disable/uninstall
it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

Whenever you install a third-party security software in Windows 8.1 or Windows 10, it automatically disables Windows Defender to avoid conflicts.

Method 3

I suggest you to follow the steps below to turn on the windows defender.

• 
  Type control panel in the search box.
  
• 
  Choose the Action Center under
  System and Security option.
  
• 
  You see the notification that Windows defender is turned off below the
  Security label. Hit the Turn on now tab to active the Windows Defender again.
