Thinking about switching to Linux

So I've only used Windows all my life and I'm thinking about switching over to Unbuntu since now Windows crap is too much for me, but I've invested so much time into Windows that I'd like to know if Linux/Ubuntu can handle regular Windows file type associations so I can carry over some of my files.

Not only the crap is my problem but from what I read, linux users are able to diagnose the problem much faster then Windows users. Can anyone else confirm this?
