On boot up, I see a message asking for installation of a USB driver for Windows Defender and also "The requested control is not valid for this service - Control Service". I have to cancel these messages to continue.
I have uninstalled Windows Defender, virus swept with McAfee, run CCleaner several times and reinstalled and run Win Defender, all to no avail. I keep seeing the same messages every time I boot up.
Can anyone think of some other way to get rid? I want to use this PC as a security camera DVR which will auto boot and load the (Swann) security software.
Try stopping the service by putting it on manual,rebooting and putting it back on auto. Change the Startup type to "Manual" from the Services Properties. Right-click Windows Defender, and click Properties to see the option
