Retro Computers (And Games): I like to play games like Terminal Velocity (1995, MS-DOS), Outrun (1991, Sega Genesis), Half-Life (1998, Windows/ 2001, PS2), Duke Nukem 3D (MS-DOS, 1996), and much more…
Assuming you mean the original windows live messenger chats, no. The original WLM servers and the servers of Escargot etc are completely different, and do not contain account data of the other servers.
(if you have an old computer with the original wlm, and chat logging enabled, check that computer’s user documents folder)
