How to Disable Windows 10 Defender

Some Win10 users complain that Windows Defender consumes too much RAM. That’s why they want to shut it down.

Windows Defender runs as a service in the background of the operating system. If this service enabled on your computer, it intervenes when you try to install a malicious program.

If you do not want Windows Defender to perform automatic actions, you can change these settings. Or, if you have purchased a quality Antivirus program, we recommend that you turn off this service, which consumes more RAM on your computer.

If you do not have an Antivirus program installed on your computer, it may be useful to activate Windows Defender.
