Hi guys. A conversation came up last night among my friends regarding Windows 7 (and Vista) and cleaning for security and privacy. There was a general consensus among the group that CCleaner (with CCenchancer) cleans everything. During this conversation I was reminded about some kind of "file" that does not get wiped by normal means. I remember reading that one would have to run a command window in order to properly wipe or reset this file -- that cleaners did not clean it nor did rebooting the pc reset the contents of this file. The way I remember it (although I had a poor understanding of it) this "file" was inherent in Windows and "recorded" browsing activity, program activity, and other things. I remember that it is something that can't be disabled, and so the best you could do was to "reset" its contents via command prompt window. It seemed to me like a pagefile type of thing, but it wasn't the pagefile and it wasn't hiberfile because those could be disabled. It wasn't index.dat either because it was something that cleaners didn't clean. I remember reading about this file on a Windows security website many years ago. The article was about law enforcement techniques and that they use this file because most people are too comfortable with ordinary cleaners and most people aren't aware of this file either. I wish I could remember more about it. The command to wipe this file was a very short command too. I'm searching all morning for any information and its driving me crazy because I am coming up empty. Any help would be appreciated.
