I agree, I think there are a few things in the Windows file explorer that conspire against its good performance (file preview is a big factor, but recycle bin content seems to affect it too), and it does seem to get worse over time. I think there's a market now for a third party 'back to basics' explorer.

7z file explorer works well for me. Now I am mostly using Linux though.
