Launch the Run dialog box by pressing Win + R keys. Type regedit and click OK. Click Yes if you get the UAC prompt. This will launch the Registry Editor.

In the Registry Editor, you have to navigate to the path written below. For this, simply copy it, paste it into the address bar of the Registry Editor, and hit Enter.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

Now, scroll down and find a key, named SecurityHealthService. Once you find it, select it.

On the right side, you will find a DWORD value, named Start. You have to change this value to 4. For this, double-click on the DWORD entry and enter the value 4. After that, click OK to save the changes.
