1.) Important points in advance:
1. Back up the registry
It is advisable to back up the registry before making changes. You can do this by going to File > Export in the Registry Editor and creating a backup copy.
2. Elevation required
To make changes to the registry, you need administrator rights.
2.) Steps to adjust the Windows Firewall via the registry:
1. Open Registry Editor
- Press Win + R , type regedit and press Enter .
2. Navigate to the relevant keys
- The settings for the Windows Firewall are located under:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsFirewall
- Under this path you will find different keys for different profiles, e.g.:
- DomainProfile (for networks with a domain)
- StandardProfile (for private networks)
- PublicProfile (for public networks)

3. Make changes
- Within these profiles you can adjust various DWORD values, e.g.:
- EnableFirewall
Enables ( 1 ) or disables ( 0 ) the firewall for the corresponding profile.
- DoNotAllowExceptions
Blocks all incoming connections, including those defined in the exceptions list, if set to 1.
- DisableNotifications
Disables notifications about blocked applications.
4. Example
If you want to disable the firewall on the public network, navigate to:
- HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsFirewall\PublicProfile
- Change the value of EnableFirewall to 0 .
5. System restart or service restart - After making the change, you should either restart the "Windows Firewall"
service or restart the computer for the changes to take effect.
3.) Alternatives:
Instead of making changes to the registry, you can also use the netsh command-line tools or Group Policy (gpedit.msc) to configure the firewall. These methods are usually more secure and easier to use.
4.) Conclusion:
Yes, the firewall can be customized through registry changes, but it requires precise work and an understanding of the settings. Backing up before making changes is essential to avoid potential problems.
5.) Options if the path does not exist:
If the registry path HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsFirewall does not exist, it means that no group policies or policy settings have been configured for Windows Firewall. In this case, Windows uses the default firewall settings configured in other parts of the registry or directly through the user interface.
1. Create manually
You can create the path manually and add the desired values to configure the firewall. However, this requires precise work as incorrect settings can cause problems.
To create the path:
- Open the Registry Editor ( regedit ).
- Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft .
- Right-click the Microsoft folder and select New > Key
.
- Name the new key WindowsFirewall .
- Within this key, you can create other subkeys such as DomainProfile , StandardProfile or PublicProfile and add the desired values in them.
2. Using netsh or Control Panel
- Netsh Commands
Instead of manually modifying the registry, you can also use netsh to configure the firewall settings.
For example, to disable the firewall for the public profile, open the command prompt with administrative privileges and type:
netsh advfirewall set publicprofile state off- Control Panel
Alternatively, you can adjust the firewall settings via the Control Panel:
- Go to Control Panel > System and Security > Windows Defender Firewall
.
- There you can turn the firewall on or off for each profile (Domain, Private, Public) and manage exceptions.
3. Group Policy Editor (gpedit.msc)
- If available, you can also use the Group Policy Editor to set the firewall policies, which will automatically create the path in the registry.
- To do this, go to gpedit.msc and navigate to Computer Configuration > Administrative Templates > Network > Network Connections > Windows Firewall
.
Conclusion:
The path HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsFirewall does not exist by default, but is only created when specific policy settings are specified. You can create it manually, but an easier and safer method is to use netsh , Control Panel, or Group Policy Editor to customize the firewall settings.
