Download this great application called CCleaner. It will safely clean out a lot of stuff.

Use this programs: System Ninja, Wise Registry Cleaner and Adw Cleaner. Works really great

Just use some tissue :)

@@lapris9000 lol, works great too ahahah

It depends what you mean by 'open'. Technically, all ports which aren't specifically denied by a ACL or firewall are 'open' ports, they may not be used at that moment, but they are open. When you do a netstat -a look after the IP Address to find which port is being used by which protocol. Do a netstat -a in your cmd prompt, and look after the colon, an example: *Proto Local Address Foreign Address State TCP 192.168.0.150:52351 52.242.211.89:443 ESTABLISHED* The protocol in this case is TCP/IP, local address is my inside-local address (192.168.0.X, in this case X is 150), the foreign address is which address I'm connected to, and the state is established, meaning a connection has been made through TCP/IP from my address to the foreign address. The 443 in the foreign address represents the port being used, in this case it's HTTPS (Port 443). Hope that clears some things up!

@@tylerc5311 If I do a netstat -a and my machine shows listening for port 445 yet in Windows firewall it is being blocked, then the port is not open. It is blocked and you would not be able to use or connect via that port. Yet netstat -a does not tell you that the port is being blocked by the firewall and it's state shows listening.
