Just wanted to chime in on the Windows page file discussion. As an IT professional, I have one piece of advice on disabling Windows' page file: Do not do it.
The "disabling the page file forces Windows to run the programs in RAM" is a misunderstanding.
This is off-topic, but if all of Sisiutils' readers begin messing with things Man Was Not Meant To Know (like essetial Windows system settings), we will have tons of "my Civ keeps crashing" posts in the technical forum.
