Within the past week or so I installed SP2 on my 64-bit Vista Home Premium\nsystem. At the time I had approximately 550 gigs free space on my hard\ndrive. Since then I've read email and have probably had some MS updates.\nI've also defragged using JKDefrag. I now have 494 gigs of free space on\nthe drive, with the biggest hit occurring after the defragging. I've\nnoticed reduced free space with other defraggers, and it has been months\nsince I last defragged, but the hit was BIG. Where does the free space go?\nI figure that Windows must eat up some but so much????\n\nAny ideas on what is happening, or even any idea which might be the best\nforum to ask my question on?
