How to block 445 port from windows firewall defender but skipping the c$ share?

Hi,

I'm blocking the 445 port from the windows firewall defender, in the inbound rules, but I'm also blocking the c$ share.

Can anybody tell me whether it is possible to block the 445 port and at the same time let the c$ share opened?

Thanks in advance.

Regards.

If you have blocked SMB/TCP 445 on the computer itself, you won't be able to browse anything via SMB on that particular computer.
