As of the year 2021, Windows Defender has been improved very much. Though its UI not changed a lot, the efficiency (CPU consumption) and accuracy are very close or equal to those famous antivirus softwares.
Today the ransomware and coin mining malwares are extremely wild, I recommend you enabling at least one security software. I think for those home users, Windows Defender is enough.
If you still want to know how to disable Windows Defender, you can go on reading.
My PC has been naked for many years because I nearly use anything unknown or dangerous.
For the older versions of Windows, which is before 1909, I disable Windows Defender in the Group Policy (gpedit.msc). Howerve, I find it doesn’t work any more.
If you install the OS all freshly and disable Windows Defender as soon as possible in the Group Policy, it will be fine. The Defender is totally sleeped.
But if you have opened and updated it once, the defender will be awakened and you won’t come back. It’s so annoying.
Even if you disable the real-time protection in the Group Policy, it will still update the data library automatically and turn on the real-time protection again.
Why must we focus on this problem?
Well, it’s funny.
You can open your task manager and find a progress or a service named Antimalware Service Executable. Click the “>” button, you will find a service named Windows Defender Antivirus Service.
The memory usage of it is very incredible, up to 100MB! And if you open a new program, it will check first, you PC will be slow, the opening of the software is slow and the memory usage will be added more.
Well, it’s not funny at all.
How to disable it?
As I said before, the Group Policy doesn’t work any more.
Here are two solutions.
You can exclude the root folder of disk drivers in Windows Defender.
Forget the Chinese language and I wish you will find the option by yourself.
