Are you looking for How To Turn On Windows Defender or how to activate Windows Defender?

Windows Defender itself is a system built-in antivirus program, which is pre-installed on Windows 8 and Windows 10 by default.

How To Turn On Windows Defender

This antivirus can be said to be very helpful, because the program is quite light, even for computers with low specifications.

How to Activate Windows Defender in Windows 10

Basically, Windows Defender should automatically turn on.

Well, but what if the current position on your computer is disabled? Suppose you have turned it off once, then forgot how to turn it back on.

For that, here I will discuss the complete tutorial. It just so happens that I also apply these steps frequently.

There are at least two general ways to turn Windows Defender back on, which are disabled, and can be adjusted as needed (later will be explained).

The first way can be through the default Windows Settings, while the second can be through the Group Policy settings ( gpedit.msc ). Please be listened to:

1. How to Turn on Windows Defender Through Settings

The settings in question are the default settings page in Windows 10, or more familiarly known as the Control Panel (although the Control Panel actually has more).

For the steps like this:

  • Step 1. First, please click the Start button on the Windows taskbar first, then click the gear icon there. More details can check this picture:

Alternatively, you can also press the Windows key + I key combination on the keyboard, or right-click the Start Menu logo and select the Settings menu.
  • Step 2. Furthermore, there will be many menus. Please check the bottom, then select the Update & Security menu.

Real-Time Protection is a settings menu to activate Windows Defender so that it can protect the system from viruses. This setting will work, both online and offline.

Usually, Windows Defender doesn’t work because this setting position is still off. By setting it to be on, antivirus protection will automatically be active again.

In addition, Cloud-Based Protection can also be activated. This setting is intended as special online virus protection.

2. How to Activate Windows Defender Through Group Policy

Group Policy is a special page, in which there are tens to hundreds of settings related to Windows systems.

For some conditions, inactive Windows Defender can only be restarted through this Group Policy setting, you know.

Therefore, this method is no less important to learn.

Well, to try it, you can follow the steps below:

  • Step 1. First, in the search column, please type ” Edit Group Policy “, then open the results.

This Group Policy is another name for the gpedit.msc command. Another step to open it, you can click the Windows key + R > type ” gpedit.msc “> then click OK.
  • Step 2 . If so, we can continue. Please enter the Computer Configuration > Administrative Templates > Windows Components > Windows Defender > Real-time Protection menu .

  • Step 3. Click the Real-Time Protection folder. Check on the right and look for the Turn off Real-Time Protection setting. Right-click the setting, then click Edit.

After the steps are applied, try restarting the computer first as usual. After that, try checking Windows Defender.

Note: This Windows Group Policy can only be active on Windows 10 Pro. For Windows 10 Home users, you can’t find the Group Policy menu later.

3. How to Enable Windows Defender Which is Turn Off by Group Policy

This condition is actually quite rare. So, when Windows Defender wants to be activated or run, the message ” Windows Defender is turned off by Group Policy ” appears.

For how to activate it not through Group Policy, but specifically through Regedit ( registry settings ) in Windows.

This method can be applied to all versions of Windows 10. Not only the pro version but Windows 10 Home too.

Please follow the steps below:

  • Step 1. First, please click the Windows + R button simultaneously, to open the Run menu.
