-a- pls for a remote login first step is to find RPI's IP
- there is a free program "advanced IP scanner" what finds the IPs in your network ( even it messes up names... )
- you can look at you router what IP are logged in (with DHCP lease )
- you can use the
windows cmd and
- - ipconfig ( show about your network and laptop IP )
- - ping 192.168.1.101
- - arp -a 192.168.1.101 ( get the MAC )
-b- second step would be to connect by PUTTY or bitvise SSH client
now you can CLI and update and fix IP your RPI and install xrdp
-c- but that xrdp install you did already at your friends place,
here the big question: did that test work there using YOUR windows 8 laptop?
( or is it the first time you try use remote desktop connection from that laptop ( win 8.1 bing... can not RDP? need win 8 PRO )
-d- in that case you could try using VNC
- - putty login RPI
vncserver :1 newpw newpw n
- - on laptop install
