Int 2F Fn 168E  - Windows95 - Title - Set Application Title                [W]

   AX = 168Eh
   DX = 0000h
   ES:DI -> ASCIZ application title (max 79 chars+NUL)

Return: AX = status
       0000h failed
       0001h successful

Note:  if ES:DI is 0000h:0000h or points at an empty string, the current
     title is removed
BUG:   this function can return a successful status even though the title was
     not changed; reportedly, waiting for two clock ticks after program
     startup solves this problem
