Windows Defender is turned off or not working

You may receive a message: Windows Defender has been turned off, and it isn’t monitoring your computer.

If you have another antivirus software installed, it will turn off Windows Defender. But if you do not and yet, then you might want to carry out the following troubleshooting steps:

1. Install the latest Windows Updates
2. Reinstall any third-party antivirus you may have installed
3. Run an offline malware scan
4. Enable Windows Defender via Action Center
5. Check Defender Service status
6. Re-register these DLL files
7. Check Registry setting
8. Perform consistency check on WMI repository.

1] Install the latest Windows Updates

Check if you have all the latest Windows Updates installed, including having the latest version of Windows Defender and its definitions.

2] Reinstall any third-party antivirus you may have installed

Did you uninstall any security software recently – especially Norton or McAfee? If so maybe its partial uninstallation is causing issues. Use McAfee Consumer Products Removal Tool or some antivirus removal tool to ensure that you have even removed its remnants.

3] Run an offline malware scan

Have you checked your computer for malware? Or did you just recover from a malware attack? I suggest you download and run a stand-alone portable antivirus scanner and run an offline scan from your USB – or else use an online antivirus scanner service to scan your PC.

4] Enable Windows Defender via Action Center

Open Action Center and see if you can enable Windows Defender.

5] Check Defender Service status

Run services.msc to open Services Manager. Ensure that the Windows Defender service is started and set to Automatic.

6] Re-register these DLL files

If Windows Defender Service (WinDefend) or Windows Defender Network Inspection Service (WdNisSvc) of Windows Defender keeps stopping, turning off or could not start,

Re-register the following dll files and see if it helps you. Run each command in an elevated command prompt one after the other and hit Enter:

You can use our freeware FixWin to reset Windows Defender to default settings.

7] Check Registry setting

Run regedit and navigate to the following key:

Here ensure that the value of these DWORDS is 1: DisableAntiSpyware and DisableAntiVirus.

If it is 0, then you will have to use our freeware RegOwnit to take ownership of these Registry keys and then change its value from 0 to 1. RegOwnit allows you to take ownership of a Windows Registry key using Administrator, Home Users, or the current Logged On User account.

8] Perform consistency check on WMI repository

It may also happen that Windows Security Center may prompt you to “Check Settings” for the Malware Protection, and when you click the “Turn on now” button, it may show an error that says “There are no new definitions available to download for Windows Defender“.

It may be possible that the issue may have been caused due to an inconsistent WMI repository. Restarting the WMI repository should thus help resolve the issue.

Open Command Prompt as an Administrator. Type the following command and hit Enter:

If you get a message “WMI repository is not consistent“, run the following command:

This will perform a consistency check on the WMI repository and resolve the issue. Restart your machine.

Try enabling Windows Defender now.

If you get the following message instead, winmgmt /salvagerepository is failed, ignore this message, and again run “winmgmt /salvagerepository“. This time, it should help.

This post titled Unable to turn on Windows Defender offers some additional troubleshooting suggestions, which may also interest you. You may also want to check the Windows Defender error code you receive and see if any resolution is available at Microsoft.
