When you run Windows defender receive error widows defender is not turned on

1. Did you make any changes on your computer prior to the issue?
2. Does the issue occur after installing another security?

If yes, you may disable another antivirus program, security & check if the issue occurs.

Perform the following troubleshooting methods:

I would suggest you to make the “Windows defender Service” startup type to “Automatic”.

Follow these steps:

a. Press “Windows key + R” from keyboard.

b. Type “services.msc” without quotes in the “Run” Window and hit enter.

c. Search for “Windows Defender Service”.

d. Make “Startup Type” to “Automatic”.

e. Restart the computer and then check how it works.

Method 2:

Perform System File Check (SFC), and then check if this fixes the issue.

Follow the steps:

a. Press “Windows Key + Q” to open Charms Bar.

b. Type “cmd” without quotes in the search box.

c. On the left pane, right click on the “cmd” option and select “Run as Administrator”.

d. Type ‘sfc /scannow’ without quotes and hit enter.

Note: It may ask for windows installation DVD to fix and to enable SFC to make more than minor repairs. Some files saved on your computer might get deleted when fixing corrupted files.
