Windows defender as an anti-virus, anti-malware, anty-spyware or whatever it’s called, is a genuine product from Microsoft that is embedded directly into the Windows operating system (supposedly since XP until now Windows 10) so that by default the newly installed operating system has protection from the dangers of viruses, malware and spyware.
Windows defender works runtime, meaning that the defender continuously monitors the system at any time so that if a threat is detected, the defender will take action (whether it directly removes or asks for action from the user).
On Windows 7 & 8, the defender can be deactivated by the user in the Control Panel, but in Windows 10 the defender has been patented (almost can’t be turned off). Actually the defender can be turned off with various risks that can arise, and incidentally a few days ago
I was exposed to one of the risks, the chronolig is like this:
1. When the laptop starts up a little longer and I try to check the lag in the Task Manager and it turns out that disk usage is full up to 100%.
2. From previous experience, Windows Defender is the one who usually becomes the culprit and when viewed on the Taskmanager, the access is big and no other is Antimalware service executable, aka Windows Defender.
3. I decided to disable Windows defender via the control panel, and sure enough after the display defender opens there is no option to turn off the service defender (which I can conclude that Microsoft really keeps the defender running and hints to the user not to turn off the defender) .
4. Because of my determination, I took another path, I went to services.msc and immediately stopped and disabled the two Windows defender services. When doing so there is a warning that appears (usually it appears), more or less warn if the service defender is stopped then there will be another service that does not work, because I feel it will not be too dangerous (usually ok too) then I ignore the warning and disable the defender .
5. The next thing that happens is that the laptop wireless adapter becomes unusable (unable to detect the existing wifi network), but it is still safe and secure on the device adapter settings and the device manager does not have an exclamation mark.
6. To solve it I try to uninstall and install the wireless driver again, the wireless adapter still won’t turn on again. Here I have suspected the cause is a defender, but I still try to improve it by diagnosing the connection and the results conclude that the WLAN Auto Config cannot be executed. I then returned to services.msc and tried to run the service manually and there was a reminder warning that caused this problem: Windows could not start Error 1068: The dependency or group failed to start the WLAN Auto Config service on the local computer. after this error I believe the cause is the defender that I disabled.
7. With the conclusion that I got, I tried to turn it on again and enable Windows defender. But the strange thing is, the service defender runs but the service wlan still thinks it’s a stop. And indeed the defender’s behavior is different because now the defender can’t be disabled anymore.
8. I tried surfing the internet and got some solutions that unfortunately didn’t work for my laptop
9. Finally I gave up and reinstalled.
In conclusion, don’t disable Windows Defender in any condition. Enough of my story a few days ago, hopefully it can provide something useful for those of you who come to visit. Thanks.
