Fiddling with the Instruction Pointer

Hello,


It has been long since I did anything with x86 assembler and now I'm
starting a small hobby project. What I would like to do is monitor the
instructions that the x86 machine is performing and when certain conditions
occur I would like to perform other operations instead of those in the
instruction pointer. Could someone give me pointers how to do this with your
regular x86 Windows XP machines. For example how to write an app that
constantly monitors the IP?


Best,

- Sami
