I need confirmation regarding customization

hello.. i've been browsing a thorough research on how to install a custom 3rd party themes on my laptop.. i did a few research such as how to make a restore and set a backup system just in case something go WRONG this is because installing custom themes involve "modification" of a few .dll files and such in the 'windows' folder.. when i'm all set.. something did go WRONG and have to use my restore point a few times and the last time i did i even have to use my Backup as my restore point was somehow corrupted when i tried restoring :shock: now everything went back to normal and i plan to try another attempt.. but something bugs my mind.. so here's the question:

• when i do change my themes to 3rd party custom.. will that affect my system in the long term..? i just figured i dnt want to some day come across a time when i start my laptop and a message like "program can't start because .dll files is missing"
  

• also.. i would like to know how can i restore my default files that i have "modified" because of the custom themes? just in case i want to return to the default settings
  

• then i would also like to know when installing the custom themes.. does that include all the orbs and the folders or do i have to do that separately?
