Windows 10 comes with its own antivirus software, Windows Defender, which provides real-time protection by scanning files on your computer. Many users prefer to install other antivirus programs, which can lead to conflicts. Additionally, Windows Defender might delete patches for certain software, prompting users to find ways to disable the Windows Defender service. This article will guide you through the process of disabling Windows Defender.

Step 1: Disable "Real-time Protection" and "Tamper Protection"

1. Temporarily disable through Windows Defender settings:

   - Open the Windows system settings, then click on Update & Security → Windows Security → Virus & threat protection.

   - In the "Virus & threat protection" settings interface, turn off the following options:

     - Real-time protection

     - Cloud-delivered protection

     - Automatic sample submission

   - If these buttons are grayed out and cannot be modified, it might be because your third-party software has already disabled them through other means.

Step 2: Modify Group Policy

1. Press the shortcut key: Windows + R, type `gpedit.msc`, and press Enter.

2. Navigate by expanding: Computer Configuration → Administrative Templates → Windows Components → Windows Defender Antivirus.

3. On the right side, double-click "Turn off Windows Defender Antivirus", then in the pop-up dialog box, select Enabled, and click OK.

That’s all about how to disable Windows Defender. If you have any further questions, feel free to follow the GameBuff Modifier WeChat public account for consultation.
