I assume you are on a home network right? port 445 is used for smb (server message block) over IP and might be needed for something like hosting a game, or rdc.

You probably couldn't close it because it was in use. If you really have to close it reboot in safe mode and close it there

first of all do you want to close them from the internal network (assuming you have router) or from the internet (assuming that you have a NAT enabled router)?
if you doing it from external network then a nat router should stop such ports from being open....:)

check out this website the XXX insert the port number)
