Windows 10: Windows Defender Firewall blocked Microsoft OneDriveFile Co-Authoring Executable

Why must I approve a firewall exception for Microsoft OneDriveFile Co-Authoring Executable? This must have been triggered by an update but might be something more dangerous.

Windows Firewall blocking websites

I have blocked IP addresses, e.g. 255.255.255.255, not URLs, e.g. somewebsite.co m.

As far as unblocking, look at your Windows Firewall rules. Do you see anything that is blocked? If you do, click on the Scope tab and see what is listed there.

 

Windows Defender Firewall showing On and Off at the same time

Hi Jerry,



Thank you for writing to Microsoft Community Forums.



I understand that the Windows Firewall shows as switched off even after turning it on. For better understanding of the issue, please answer the questions below.

1. Which build version of Windows are you using currently?
   
2. Are you aware of any changes being made to the PC?
   
3. Do you have any security software/firewall installed?
   

Meanwhile, I would suggest you to follow the steps mentioned below and check if that helps.



Method 1:



I would suggest you to run the troubleshooter for Windows Firewall and check if that helps. Refer the article

Automatically diagnose and fix problems with Windows Firewall



If the above method doesn’t t work, please follow the next method.



Method 2:



I would suggest you to try enabling the services responsible for Windows Firewall and check if that helps.

1. Press Windows key + R. This will open
   Run. Alternatively, you can go to Start and search for ‘Run’.
   
2. In Run dialog box, type services.msc and hit enter.
   
3. Now look for the services: Security Center,
   Windows Defender Antivirus Service, Windows Defender Firewall Service,
   Windows Defender Advanced Thread Protection Service,
   and Windows Defender Antivirus Network Inspection Service.
   
4. Right click on each service and click on Start.
   

If the above method doesn’t work, please try the next method.



Method 3:



I would suggest you to check if any conflicting registry entries are present which are blocking Windows Defender Firewall to turn on.



Note: Important this section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow
these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.



Refer the article on
How to back up and restore the registry in Windows

1. Press Windows key + R. This will open
   Run. Alternatively, you can go to Start and search for ‘Run’.
   
2. In Run dialog box, type regedit and hit enter.
   
3. Now navigate to the location: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
   
4. Look if there are any registry keys named: MSASCui.exe, MpCmdRun.exe or MsMpEng.exe.
   
5. If there are any such entries, then delete them by right clicking and selecting Delete.
   
6. Click on Yes.
   
7. Restart the PC.

Best free AV and firewall

Can Windows Firewall block outgoing connections yet? If not, it's one step above useless.
