Deactivating Windows Defender

A straightforward method for disabling Windows Defender involves utilizing the application itself. Begin by clicking the Start button, then type "Windows Defender" into the search field. Launch the application when it appears in the results.

Next, navigate to Tools and subsequently select Options within the program interface.

Within the left-hand panel, click on Administrator. This will reveal a checkbox labeled Use this program. Simply deselect this checkbox and then click Save to apply the changes.

Upon successful completion, a dialog box should appear, informing you that you must now employ alternative software for spyware monitoring.

This action should effectively disable Defender, but for added assurance, we will also disable the service directly.

Click the Start button and search for "run". Launch the application and type services.msc into the provided box.

Scroll down the list of services until you locate Windows Defender. Right-click on it and select Properties.

In the properties window, the Startup type is likely already set to Manual. Change this setting to Disabled to ensure the service does not start automatically.

As a final precaution, it’s advisable to verify that Windows Defender isn't configured to launch during system startup. This will help prevent potential errors after disabling the service.

Type "run" (without quotation marks) into the search box in your Start menu. Click the application when it appears, and then enter "msconfig" into the text field before pressing OK. This will open the Microsoft Configuration Utility.

Select the Startup tab and look for Windows Defender. If present, uncheck the corresponding box and click OK. You can disregard any prompts requesting a system restart.

You have now successfully stopped the Windows Defender service and prevented its future startup. It is recommended to install a reliable anti-spyware application as a replacement.
