Windows Firewall can be disabled through Settings or Control Panel, but you should know what you're turning off before you do

Windows Firewall is a built-in tool that monitors incoming and outgoing network traffic on your computer. Disabling it removes that protection layer entirely. Most people should leave it on. If you need to disable it temporarily to test a network connection or because a program isn't working, you can turn it off in Settings or Control Panel — but you'll want to turn it back on when you're done.

The fastest route is through Windows Settings. The older Control Panel method still works if you prefer that interface. Both reach the same firewall, so either approach gets the same result.

Key Takeaways

  • Windows Firewall can be disabled in Settings under Privacy & Security, or through Control Panel's Windows Defender Firewall section.
  • You can turn off the firewall for all networks at once, or disable it only for private networks while keeping it on for public ones.
  • Disabling Windows Firewall removes protection against unauthorized network access, so turn it back on as soon as you've finished testing.
  • If a program won't run with the firewall on, adding that program to the firewall's allowed list is safer than disabling the entire firewall.

Disable Windows Firewall through Settings

Open Settings by pressing Windows key + I. Go to Privacy & Security on the left sidebar, then select Windows Defender Firewall. You'll see options for Domain network, Private network, and Public network — each can be toggled separately.

Click the toggle next to "Windows Defender Firewall" under whichever network type you want to disable. A warning will appear asking you to confirm. Click "Yes" to proceed. The firewall for that network type is now off. If you want to disable it for all three network types, repeat this step for each one.

To turn it back on, return to the same screen and click the toggle again. It will switch back to on.

Disable Windows Firewall through Control Panel

Press Windows key + R to open the Run dialog. Type control and press Enter. In Control Panel, search for "firewall" in the top right search box. Click "Windows Defender Firewall".

On the left side, click "Turn Windows Defender Firewall on or off". You'll see options for Domain network, Private network, and Public network. Under each one, select "Turn off Windows Defender Firewall (not recommended)" if you want to disable it for that network type. Click "OK" to save the change.

Allow a specific program instead of disabling the whole firewall

If a single program isn't working because of the firewall, you don't need to disable the entire firewall. Instead, you can add that program to the firewall's allowed list. Open Settings, go to Privacy & Security, then Windows Defender Firewall. Click "Allow an app through firewall".

Click "Change settings" at the top, then "Allow another app". Browse to the program's .exe file and select it. Check the boxes next to "Private" and "Public" depending on which networks you want to allow it on. Click "Add" and then "OK". The program can now communicate through the firewall without you having to disable the entire protection.

What happens when Windows Firewall is off

With the firewall disabled, your computer has no built-in barrier against unauthorized network connections. Malware, viruses, and other threats can reach your computer more easily if they're on the same network. This is why disabling it is not recommended for everyday use.

If you're on a public network — like at a coffee shop or airport — leaving the firewall off is especially risky. If you must disable it, do so only on a private network you trust, and only for as long as you need it.

Turn Windows Firewall back on

Return to Settings > Privacy & Security > Windows Defender Firewall, or use Control Panel's Windows Defender Firewall section. Toggle the firewall back on for any network type you disabled it for. The protection is now active again.

If you added a program to the allowed list and no longer need it there, you can remove it. Go to Settings > Privacy & Security > Windows Defender Firewall > Allow an app through firewall. Find the program in the list, select it, and click "Remove". It will no longer have special firewall access.

Frequently Asked Questions

Will disabling Windows Firewall speed up my internet?

No. Windows Firewall runs in the background and uses minimal system resources. Disabling it won't noticeably improve internet speed or computer performance. If you're experiencing slow speeds, the firewall is not the cause.

Can I disable the firewall just for one program?

You can't disable the firewall for just one program, but you can allow a specific program through it. This is safer than turning off the entire firewall. Go to Allow an app through firewall in Windows Defender Firewall settings and add the program you need.

What's the difference between disabling it for private networks versus public networks?

Private networks are ones you trust, like your home WiFi. Public networks are shared spaces like coffee shops. Disabling the firewall on a public network is much riskier. If you must disable it, do so only on private networks and only temporarily.

If I disable Windows Firewall, do I need a different firewall?

If you disable Windows Firewall, you lose that protection entirely unless you install a third-party firewall. Most people should keep Windows Firewall on. If you're testing a network issue, disable it only long enough to confirm the problem, then turn it back on.
