You can do this to any Windoze DLL or EXE file.
look for the byte 0xCD, and replace it with 0x90
0xCD is the intel machine code for a CALL statement, which causes the
processor to jump to a new location and execure some time-wasting code.
0x90 is the intel machine code for a NOP statement, which is a far
more efficent routine that does nothing for 1 clock cycle.
Replacing all of your 0xCD's with 0x90's will dramatically speed
up the program. The program will not work , or do anything useful
after this, but who is to say that the original Windoze program
actually worked in the first place ? There is even a chance that you
may fix problems in the program by bypassing all of the function calls.
