Deauthorizing iTunes/Shopping Cart Help

[chameeeleon]

Is there any way to deauthorize computers authorized for iTunes music that I no longer have access to, and that (even if I did have access to) are so Windows-ed up that they won't boot anymore?

And another quick question - if I put things in my Shopping Cart on one computer, and then log into my account on another, and enable shopping-cart buying, will the songs still be in there?

Any help greatly appreciated, and sorry if there's already a post like this - I searched quickly but couldn't find.

Just did this last week...

Had a authorized PC harddrive crash and had to deauthorize it after.... whet to this apple support page and explained my issue to them in the provided form. They simply deauthorized all my listed computers and I had to reauthorize the valid ones as needed .. took them about 3 days to get back to me.
