The most direct way to turn off the Web Security feature is through the standard Windows Network & Internet settings menu.

Microsoft Defender's VPN and Web Security features are deeply integrated into the Windows operating system. When active, they scan and route web traffic, which can sometimes consume extensive resources or clash with third-party VPNs.

Disabling this setting directly from the native Network & Internet menu is the safest method to restore system responsiveness.

Click on the Start menu and select the gear icon to open Windows Settings, or simply press the Windows key + I on your keyboard.

2
Navigate to Network & Internet

In the Settings window, click on the 'Network & Internet' category from the available options.

3
Locate VPN Settings

Look at the left-hand navigation pane and click on 'VPN' to view your active virtual private network connections.

4
Turn Off Web Security

Find the Microsoft Defender VPN Web Security entry in the list, click on it, and toggle the feature off or select 'Disconnect'.

5
Verify System Responsiveness

Open Google Chrome or your preferred browser to check if the computer's performance and responsiveness have returned to normal.

Frequently Asked Questions

Why does Microsoft Defender VPN Web Security slow down my computer?

The Web Security feature continuously scans your incoming and outgoing web traffic for malicious content. This real-time inspection can consume significant network bandwidth and CPU resources, occasionally leading to lag in browsers like Google Chrome.

Can I use another VPN while Microsoft Defender VPN is active?

Running multiple VPNs simultaneously often causes routing conflicts and connectivity drops. It is highly recommended to turn off Microsoft Defender VPN Web Security before enabling a third-party VPN service to ensure a stable connection.

Is it safe to turn off Web Security?

While turning it off resolves performance issues and software conflicts, doing so removes an additional layer of Microsoft's web filtering. Ensure you have reliable antivirus protection active and always practice safe browsing habits.

Will turning off the VPN affect my Microsoft Office or WPS Office applications?

No. Turning off the VPN will only affect your network routing and web filtering. In fact, disabling a conflicting VPN can actually improve the sync speeds and performance of cloud-connected productivity apps like WPS Office.
