Windows Firewall cannot be started

Windows Firewall cannot be started to solve the problem of releasing an image of the system disk on the Internet. If no virus is found, the system is carved into a disc, and the old machine in the house is redone to the system, which is very slow, it seems that the disk is not clean. After the virus is killed, it is found that the firewall cannot be turned on. I have never encountered this problem before, so I searched the internet for a solution and sorted it out as follows. 1. Firewall Configuration Error start --> Run --> gpedit. msc then, the Group Policy is turned on, and the computer configuration is displayed on the left --> management template --> network connection --> Windows Firewall. Below are some options for force restriction of the Group Policy. the configuration you need is defined as enable and then set back to "not configured" (some software changes the registry, sometimes it cannot be displayed in the Group Policy, and the Group Policy may not be configured after the change, so you need to configure it and then configure it back) 2. The option for enabling the security center disabled firewall becomes gray and cannot be enabled. The prompt "due to security concerns, some settings are controlled by group policies" www.2cto.com is prompted to run services. msc enables "service" to set Security Center to automatic and enable. Set Windows Firewall/Internet Connection Sharing (ICS) to automatic and enabled. Set Application Layer Gateway Service to automatic and enable. If you still cannot enable the firewall, perform the following steps: Run regedit.exe to open the registry and delete the following two items:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ WindowsFirewall HKEY_CURRENT_USER \ SOFTWARE \ Policies \ Microsoft \ WindowsFirewall (at least one item can be found) restart Windows Firewall/Internet Connection Sharing (ICS) in the service) if you continue to prompt "some settings are controlled by group policies due to security considerations", the usage will not be affected. Iii. System File loss because the SharedAccess. reg file is lost or damaged, the SharedAccess. reg file represents the Windows Firewall Service. Note: The Windows Firewall Service replaces Windows XP sp2 with the Internet Connection Firewall (ICF) service in earlier Windows XP versions. To solve this problem, use one of the following methods.
