On my laptop, superfetch (Vista RTM - last updates) make my laptop slow down a lot.
Superfetch analyze and things many files needed to be superfetched but this is not true.
It try to preload VMDK (VmWare) files, and files accessed frequently by emule.. :'(
Impact of many I/O on notebook's hard drive is huge. Because then on next boot superfetch wants to read all this files to preload them. Even with the QOS, on a 5400 tr/mn this has much impact.
Any clue on how to exclude folders or files type from being superfetched ?
