this whole time i thought it was either home or pro! i am in the process of building a new pc so i went to go get an operating system. i saw the home was $99 and $199(pro$199 and $299). i was like uh, but then i looked closely and one was an upgrade version and the other was a full install for pc's that don't have windows. this was the first time i saw or found out about this. you guys are probably laughing at me but i'm trying to get into the pc thing as much as i can. it's just any time i see windows for sale online, it's only one version of each and most of the time it says full version. for example, monarch pc is selling home for $89 and it says it is the "full version", so which one is it? the price makes me believe it's the upgrade but the description makes me believe it's the full version. obviously i will need a full version since the hd is new. help me!
