I setup a virtual machine on my 2008R2 server and it's running vista. I was wondering if 512MB ram would be enough if all i'm doing is using it to connect my 360 as an extender. I setup the vista machine and it works but i'm not sure if it'll have enough ram. Also is there any features or anything I can turnoff in vista to speed it up. I won't ever be actually on it unless I need to change a setting but I don't want my extender media center to be slow.
