New to bootcamp and have been out of the Winx world for 15 years or so. I was surprised (badly) at how much space Winx is taking up. Boot camp suggested a 20 GB partition when I first installed Win7 pro and that was eaten up almost immediately. Even though the actual Win system folder was small, on the order of 11 GB, and I'd only installed one 350 MB program, suddenly I was out of space. I've bumped up to 30 GB and still run out of space.
I understand that many folks recommend 40 - 60 GB partitions, but I don't have a lot of space on my current HD, so that's why I'm stingy.
But the real bottom line is that I'm just amazed at what a resource hog Win7 is.
16 GB ram, and it wants 25 GB just for a swap file.
I've limited the size of my max page file, turned off Recovery, and done a disk clean up. Sometimes I have 11 GB free, sometimes 35 MB. The swings are pretty erratic. I may have to just bite the bullet and just buy a 1 TB HD, but I won't go there smiling.
