There are a couple of ways to fix this kind of error on your Windows PC. You need to open the task manager and click on the services tab and then click on the all services link at the bottom. Or you could go to the services.MSC using the start menu. Now, you have to find the security service and then open its properties.
Then, you have to click on the General tab and set the startup type to Automatic (Delayed), and you will be good to go. You also have to click on the start button to start the service. You may also have to repeat the same for WMI and RPC if that does not work for you.
