How to delete a printer port for assigning a new one

For some reason, you wanted to install the same printer to your computer but your computer is still using the same IP address that you set up with the printer before, and without installing a fresh copy of the printer's driver and software, you will not maximize the potential of your printer. So here's the way:

1. Go to Printers and Faxes in Control Panel
2. Right click on the white space in the window
3. Select Server Properties
4. Go to Ports tab
5. Select the port number that you wanted to delete, then Delete.

That's easy!
Another solution is by going through the registry:

1. Start, Run, type regedit
2. Follow the path:
HKEY_LOCAL_MACHINE>>SYSTEM>>ControlSet001>>Control>>Print>>Monitors>>Standard>>TCP/IP Port>>Ports\
