You need to use completion ports on Windows. There are many online articles on how to use them.

select() tends to degrade for large sets of sockets due to the need to rebuild the fd_set, and the way it gives results.

The epoll() API on Linux is perhaps my favourite method of dealing with multiple sockets. You might take a quick look into it, but it is not available on Windows.

I believe the only way around select()'s limitations on Windows with that many sockets is to use IO-completion ports.
