Not working addons

Hello fellas. Before few months I bought a new PC and I'm on Windows 10 now. So straight to the problem. I downloaded WoW, also downloaded a lot of addons, but then i realised something... only GearScoreLite is working from all of them( I used all of them before and yes i know how to use addons and how to configurate them). The first think I did was to delete the WTF folder... aaaand nothing. After that I installed VC pack... same. Can you help me somehow? With advice for example?
Thanks a lot ! :)

I'm not very techy but for me It's almost always because the addons are not extracted into the right place or they have been extracted but are still in a main folder rather extracted out of that and into the addon folder.
