For some reason the top result for the Google search “wget for Windows” still returns an old (1997) page. The version on that page is an ancient one - v1.5.3.
A much more current build is available from Bart Puype’s page at http://users.ugent.be/~bpuype/wget/. He’s building Windows versions with Visual C++ that are based off the more current 1.10.x version (which, most importantly, includes working support for Large Files - files greater than the magical 2.1GB barrier).
So if you are looking for wget for Windows, hit up Bart’s page for a more current version. He also includes helpful instructions on how to build it yourself with Visual C++, which might be handy given it is a bit of a puzzle.
