New windows 10 is very sleek and keeps updating based on great community feedback participation- they've even contacted me about using windows on their official account!
Changing remote settings probably wise

Can change the default startup OS here

if have another version of windows already installed as long as you have space you can partition the drive and keep both!
Peer block is also nice

*disable if want to update windows or windows store /other stuff to work in menu possibly/some apps- basically like a firewall *
but if have that and want to play the game will have to add some servers to white list. some IP blockers and and anti virus software or firewalls can cause a delay in traffic.
if have done a bunch of free crystal ads like me and get bugs every bit XD sometimes wiping stuff through a system like http://www.ubuntu.com/desktop
then wiping it with windows &installing one of each will do super clean install(wipe with linux then wipe with windows -install windows then linux / old windows had from cd or recovery cd)
