On Windows 7 VMware client Powershell error for Firewall rules delete

On the Host machine ( Windows 10 ) I Get downloaded all the command lets. But on Vmware workstation based VM ( Windows 7) I am not able to delete the persistent rules since the Ge-Command -- fails to download. Network connection is not an issue. PS is with Administrative power. Using RegEdit I clean the BFE keys under CurrentControlSet, when I reboot, reg entries are gone. But netsh wfp show filters creates the xml file with all the filters I added.

I add rules using WFP Api, and it does not show in the Defender Firewall App, so I can not delete from there.

Is there a way to clean all the rules from the VM ( Windows 7). So I can continue testing without old rules being shown ??
Thanks,
Prokash

Hi,

The Remove-NetFirewallRule cmdlet is from the NetSecurity module which is only available on Windows Server 2012 or later and cannot be installed on Windows 7.
You can use netsh advfirewall firewall delete instead.
