Maybe the executable can have a list of the optimization steps, and you could just put a check mark one by one, until you feel confortable with the optimization.
I dont know if I explaind myself but i will try to summarize below:
You run the exe which is like an installer, on the screen the exe shows a list of each step in which you can put a check mark on the first item and tell the exe to do that step, then run it again and go to the second step, tell the exe to do that step and so on and so forth.
Just an idea

PS maybe the exe can undo the steps too, so if by doing for example step 5 the computer becomes unstable, you can run the exe again and tell it to undo step 5
