Olly is easy for newbies but SI is better. I think.

olly is free, sice is very difficult to get the latest version.
i prefer the simple olly, and used sice only when olly cant do a thing.

i rarely do debugging, and putting sice will make windows have debugging drivers always. i like to keep windows clean..

so i use olly when i want, small, no drivers, no integration into window..

May be it can Inside Kernel :confused:

I personally prefer SoftIce for debugging programs. I only use Olly for debugging the app while I am coding a Keygen for it, so I can code the Key Algo and check what must be done whitout stopping the whole system.

Softices docs show the line and where it is that starts softice.
I used older v 3.63 and I used to just comment out the startup line and reboot the computer. When softice is needed, just take the comments off
and reboot again. It isn't elegant, but it will let you have softice on your computer without it running all of the time. The line used to be in the autoexe.bat file on my old win98se I think.
