Win7与XP不同，在开启远程桌面修改端口后是无法直接访问的，原因是还未修改远程桌面在防火墙入站规则中的端口号。
修改远程桌面端口：
[HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Terminal Server/Wds/rdpwd/Tds/tcp] PortNamber
[HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Terminal Server/WinStations/RDP-Tcp] PortNamber
修改远程桌面在防火墙入站规则中的端口：
[HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/SharedAccess/Defaults/FirewallPolicy/FirewallRules] RemoteDesktop-In-TCP
[HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/SharedAccess/Parameters/FirewallPolicy/FirewallRules] RemoteDesktop-In-TCP
