Windows 10: Windows Defender speed issues. Just crazy

I am sure there are many threads existing concerning this topic. As this thread:

https://answers.microsoft.com/en-us/windows/forum/windows_10-performance/windows-defender-real-time-protection-service/fda3f73e-cc0a-4946-9b9d-3c05057ef90c


is closed, I wanted to open a new thread. It`s not a question it`s more a kind of tip for others, because Windows Defender made my new laptop extremely slow.

In fact, my Pentium P6200 processor was faster than my new 8 core 1000$ laptop. Specifically, in Visual Studio 2005, the old laptop was three times faster. Before that, I installed Visual Studio 2019 in my new laptop, but instantly removed it, as I figured out I had to wait seconds for basic click operations. New Project -> wait 5 seconds. New file, again wait 3 seconds. Compiling, endless joy. I didn`t notice the speed penalty of Windows Defender instantly, it took some time.


Luckelywise I tried first to deactivate Windows Defender which brought me success. Now its the reverse, its many times faster than my Pentium laptop.

So, this is the quote I want to point out from the linked thread from the user darylknight:


"I'm surprised there aren't more comments on this. I just moved from OSX to start front end development on my desktop Windows 10 machine and this Antimalware Service Executable is crippling everything; especially when staging new repositories or unzipping stuff. I just unzipped a small archive; it took 3 seconds with real time protection off, and 20 with it on."


We are talking about an abnormal speed impact. Windows Defender activates itself, ignores the registry entry if an alternative Anti Virus is not installed. So Windows 10 has to be configured properly to run again at old Windows 7 performance, but reading this:

I think Windows is self destructing itself.
