If you simply want to use a Subversion client on Windows, the best option is TortoiseSVN.
If you want to have your own Subversion repository, then do the following.
Subversion involves two kinds of parties: the server, which has all the data necessary to construct the repository, and the client, which performs most of the user-initiated operations against the repository. You need to do a few things:
- Set up a Subversion server.
- Add or create the relevant repositories.
- Make sure the server is visible to all the clients that want to see it.
Then each client simply accesses the server the same way, e.g. svn co http://mycomputer/svn/shared/trunk
