I am sure this has been debated and/or discussed frequently. I am looking to build a new pc, but I want to know if I should go with windows 7 or whs2011. My main uses for it would be to stream my media on my network, to my other computer, google tv, xbox, etc. How effective is Windows 7 at sharing across a network? And if I went with whs, does it allow basic programs to be installed or is that something difficult to do? Such as vlc, games, chrome etc. Any help and input is appreciated. Thank you very much.
