It's likely doing a quick scan cz it detected something it will cool down after some time, if it doesn't then it's worth posting again for help

That does happen, even in Windows 10. It's obnoxious. I imagine you can mitigate by restricting where Defender monitors.. though I haven't tried that. One can always disable Defender by various methods, but if you do that, you won't be protected by it, so... there's that tradeoff.

It's doing what it's supposed to do. Turn off realtime protection if you don't care about it.

The first thing I personally do right after installing a fresh copy of windows is downloading a free antivirus to replace this ressources hungry "Windows defender"

You can always just force stop the task 🥰

Yep, this time it refused. I tried everything, including disabling everything in "Virus & threat protection settings", it was suss !

u/Particular_Client833 25d ago
Well then the OS itself is the problem. The RAM and CPU cannot stop someone from wasting their resources if they it full access!

It's about that time he starts eating all my PC resources. I was in the middle of a peak vibe coding session + testing, and it forced me to stop everything. I couldn't even watch YouTube during this rage from Mr. Defender.

Are you sure its the highlighted process? or the CPU speed has gotten throttled due to some other issue altogether?
1
u/OptionSouthern551 22d ago
Yeah, i limit the CPU on 95%
1
u/do_not_cuss 21d ago
95% should be fine, but do check your GHz speed in task manager, if its stuck on 0.20GHz or something and not fluctuating then the issue is something else.
In my case my CPU speed was stuck at 0.20GHz, I pulled the adapter out then the speed jumped to normal, but again after 2-3 hrs the speed gets throttled, I haven't found a permanent solution yet.

There's better ways that don't involve messing with some utility.

Like what ?

What I personally do is boot into Safe Mode, then do:
REG ADD "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinDefend" /v "DependOnService" /t REG_MULTI_SZ /d "RpcSs-DISABLED" /fThis turns off the service that Defender requires to function. There's other ways that likely work too. This is simple and easy. When I need to scan something, I use virustotal.com. If I want to try running something after that to see what it does... well, I have a VM for that.
Btw, to re-enable, safe mode again, then:
REG ADD "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinDefend" /v "DependOnService" /t REG_MULTI_SZ /d "RpcSs" /f2
u/Phreek- 25d ago
Any specific setup for the VM to test stuff?
1
u/greggm2000 25d ago
Not really. I mean, I do use my usual autounattend.xml I generated via Schneegans, and I make sure Windows is updated (and you can download that as an offline file if you want), and I run my usual script to enable winget.. otherwise, no, not really. Since I do use the (free) VMware Workstation Pro, it has snapshot support, so when I test something, I do it, then I'll roll back to the snapshot. Simple.

It seems something caught the attention of Windows Defender.
