There is a free Skyrim Mod Manager out there. It allows you to see, install, and uninstall all mods with Skyrim. I'm sorry I can't get the link for you. Games sites are blocked here at work but if you google and search around you should find it.
i use this site http://skyrim.nexusmods.com/ to download all my mods. Theres a free download manager and it will automatically change anything for you. If you dont like it you can just deactivate the mod in the manger and you game will be back to normal. If you already modded the game using something different, your probably best uninstalling the game and starting from scatch to get everything back to normal.
