To restore Windows Firewall’s default settings in Windows 10 or Windows 11, open Windows Security, select Firewall & network protection, then choose Restore firewalls to default. Confirm the restore if prompted. This resets firewall configuration; it does not reinstall Windows or reset all network settings. Microsoft documents this option for both Windows versions.
Restore Windows Firewall defaults
- Open Windows Security. You can search for it from the Windows taskbar or Start menu.
- Select Firewall & network protection.
- Select Restore firewalls to default.
- If the Windows Defender Firewall dialog appears, confirm that you want to restore the defaults.
Microsoft describes this as restoring the firewall settings that were in place when you first obtained the computer. The control is a targeted firewall reset—not a Windows reinstall, System Restore, or general network reset. Microsoft Support: Firewall and network protection in the Windows Security app.
What changes when you restore defaults?
The action restores the firewall configuration to its default state. If you had added custom rules or app exceptions, a program that depended on one may no longer connect until you create an appropriate exception again. The reset does not mean you should switch the firewall off to get that program working.
If an app is blocked after the reset
First confirm that the app is one you recognize and trust. If it needs firewall access, add a limited allowed-app exception rather than turning off firewall protection. Microsoft says allowing an app is generally less risky than opening a port: an allowed app opens the ports it needs only when required, while an opened port remains open until you close it. Both actions carry risk, so use only the exception necessary for the app’s legitimate function. Microsoft Support: Risks of allowing apps through Windows Firewall.

- Open Windows Security and select Firewall & network protection.
- Select Allow an app through firewall.
- Review the listed apps and allow only the recognized app that needs access. If it is not listed, use the option to add an app and select its program file.
- Save the change and check whether the app works. Remove the exception when it is no longer needed.
Opening a specific port is another possible exception, but it is generally riskier than allowing an app. Only do it when the app or service specifically requires that port, and close the port when the need ends.
If the restore option is missing or settings return
On a work- or school-managed computer, an administrator may control firewall settings. Policy can prevent changes, and policies applied to the firewall will be reapplied after restoring defaults. If the control is unavailable or your settings revert, contact your organization’s administrator instead of trying to bypass its management. Microsoft explains how organization policies affect the firewall.
