First of all, if this is the thing that is really bugging you, then life must be going quite well. Secondly, there is the views tab which will change the look of your folders, but more than that, there is a slider that will give you further changes until the folders look just like they do in XP. The particular option you require is removed, but providing you speakadaeeenglish, then you should be able to naviagte without too much trouble.
If that fails to satisfy, then seek out your nearest park, go for a walk, play on the swings, eat a burrito, enjoy the sunshine

No need to thank me, the advice is free of charge.
