Hi I am not sure what version I should buy windows 7 home premium or windows 7 pro edtion. I am running xp pro right now but I am not sure if windows 7 pro edtion is worth the extra money from the charts I seen its mostly like encryption they add and remote desktop and stuff like that what I prob would not use anyways. What I run most of the time and I am most concerned about is will premium come with the option to install IIS? Then should I get 64bit or 32bit? I am kinda scared my stuff won't work or my programs I use won't work.
