2. Uninstall VPN software and extensions

The Windows Firewall has blocked some features error can also be due to VPN client software and extensions.

So uninstalling VPN software, might fix the issue if you’ve installed a VPN client. In addition, check if there are any VPN extensions enabled for your browser.

One way to easily get around this issue is to simply have a dedicated uninstaller that will remove any program from your PC, extensions included.

One such tool is IObit Uninstaller 10 Pro, and not only will it remove software, Store apps, and extensions, but it will also remove the residual data that would be normally left behind during a typical uninstall.

The program is easy to use, and once your VPN is completely removed, you can go ahead and try enabling Windows Firewall again.

3. Open the Windows Firewall Troubleshooter

The troubleshooter is not included in Win 10, but you can download it from this webpage. Open the troubleshooter from the folder you saved it to, and click Advanced to select the Apply repairs automatically option.

Then you can click Next to go through the troubleshooter.


4. Turn Off the Windows Firewall

  • Open Run with the Windows key + R.
  • Enter Control Panel in Run’s text box, and click the OK button.
  • Then enter firewall in the Control Panel’s search box, and click Windows Defender Firewall to open further options.

  • Select Network adapters to expand that device category as below.

  • Right-click your VPN network adapter and select Disable device.
  • If you’re not sure which one is the VPN adapter, just disable each network adapter one at a time to see if that fixes the Windows Firewall alert.

If you prefer to keep the VPN software, try disabling the VPN‘s network adapter via Device Manager. Some users have confirmed they’ve fixed the issue by disabling a network adapter.


7. Restore the Firewall to its Default Settings

  • Open the Control Panel.
  • Type ‘firewall‘ in the Control Panel’s search box, and click Windows Defender Firewall.
  • Click Restore defaults to open the options shown below.

  • Then you can press the Restore defaults button.
  • A Restore Defaults Confirmation window will open. Click Yes on that dialog box to restore the default settings.
