Windows can't display the solution of windows firewall settings

When I checked the server for a client today, I found that the Windows Firewall could not be opened, and the following error message was displayed:

Windows cannot display Windows Firewall settings due to unrecognizable problems

Go online to find a way, computer software and hardware application network (http://www.45it.com.cn) tells you to import the following registry file and restart the system will be good.

1. Copy the following text into "Notepad" and save the file as Sharedaccess.reg:

Windows Registry Editor Version 5.00

2. Double-click "Sharedaccess.reg" to incorporate the contents of this file into the registry. And create a Windows Firewall registry key.

3. Restart Windows.

4. Click Start, click Run, type cmd, and then click OK.

5. At the command prompt, type the following command and press Enter:
Netsh firewall reset
6. Click Start, click Run, type firewall.cpl, and then Click "OK."

In general, the import registry is restored after restarting. The following is Microsoft's official reference material:
