I am trying to play Turok 2 but Windows does an irritating work. After running once, PCA puts in a custom shim in the registry, which is in the attachment. This is not a user-applied setting, the issue of it is that the game loses it's resolution list and I can no longer play the game until I go to the exact same location and delete the registry. Now what I do is stop PCA permanently, which I don't want as well for other reasons.

Can anyone assist on telling how they operate and these are applied and a possible way to circumvent them from happening, except for the aforementioned methods?
