How to disable Windows Defender in Windows 7?
In certain situations, temporarily disabling Microsoft Defender in Windows 7 is not the best solution for the task at hand. For example, such a situation is when you plan to install another antivirus program instead of Windows Defender or activate windows with kms programs. Therefore, in this case, it is more advisable to disable Microsoft Defender in Windows 7 permanently using a special method.

Turn off Windows Defender permanently
At the same time, it must be said that disabling Microsoft Defender in Windows 7 permanently does not mean deleting this utility. Disabling Windows Defender permanently means that after restarting the computer, this antivirus will not turn on automatically. If necessary, Microsoft Defender can be enabled manually. We add that the proposed method to disable Windows Defender is not easy, so two steps should be taken initially:
a) you need to create a restore point;
b) it is important not to make mistakes and follow the instructions clearly:
1. Use the key combination “Windows + R” in the window that appears, enter the command regedit and click “OK”

2. A window will appear, copy the address path
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
and paste it at the top in the search bar and press “Enter”
3. In the left pane of the window, find the “Windows Defender” folder, right-click on it and select “New” in the menu that appears, select the “DWORD (32-bit) value”

4. Click the DisableAntiSpyware parameter in the right panel, in the window that appears: “Edit DWORD (32-bit) Value” in the “Value Data” field, specify the value 1 and click “OK”

All that remains is to restart the computer and Microsoft Defender in Windows 7 will be disabled forever!
