sudo apt-get install xrdp

2.Open Remote Desktop Connection in Windows 7.(click Start button,then search “remote” in search box)

2.Input the host name or IP address of your Ubuntu machine ,then click Connect

3.Input your username and password of Ubuntu ,then click Ok to connect

4.You are done,enjoy
