Windows 10: Windows Defender is Stuck and I Can't change it.

My laptop windows 10 has been acting sluggish of late. Task Manager consistently shows "LocalServiceNoNetworkFirewall" at about 25% to 40% CPU and the fans run constantly when the laptop is plugged in but will stop when running on battery. The sub tasks? are Windows Defender Firewall and Base Filtering Engine BFE services. Services shows Windows Defender Firewall as "starting" but never anything else. All options Start, Stop,. Pause Resume are greyed out and thus inaccessible. I believe this is the problem. BFE appears to be running, however.


I do have other virus/firewall software running, including Avast, MalwareBytes, and required by employer, although this is my own computer SentinelOne Agent. I understand there could be some conflict here but not sure how to identify what that conflict might be specifically, and just want to get Windows Defender Firewall to stop.


I've run updates, rebooted a few times, tried to start/stop Windows Defender Firewall from settings, etc.

Help!

:)

Choice of memory and motherboard... a bit stuck...

No one who got some suggestions on this one, huh?

I've found out that the Asus M3A78-T needs to be flashed, so then that motherboard is excluded from my list. Which motherboard and memory should I then go for? Any suggestions?

Hi Joseph,

If not would suggest you to follow the below steps.

• Type “Services.msc” in the “Run” command box and press “Enter”.
• In the “Services” window, search for the “Windows Defender” service from that list.
• Double-click on it to open its “Properties” window.
• From its “Properties” window, click on “Start” when the service is stopped and also change its “Startup Type” to “Automatic”.
• Click on “Apply” and “Ok”.
• Restart the computer and check if that resolves the issue.

I also suggest you to try following method to resolve the issue.
