I close vids in WMP and they reopen where I stopped them.
VLC has the same quality as WMP, it's free, and plays many files automatically (unlike WMP,.iso files, for instance) and can be set up to play Bluray.
I like WMP for the quality of the video, and ease of use.
I play .VOB files mostly, basically DVDs. And mp3s, and 4s, and some movies I saved in .iso.
VLC and WMP look the same, quality wise, and can be used for most videos.
VLC is a project of a University in Denmark, I believe. Free online.
