I've unchecked the "run on a schedule" on Vista's Disk Defragmenter
but it will still automatically defrag when the machine is idle, if it considers it necessary.
"virtual" software I'm using will be bolloxed if a defrag occurs while I'm using it.
So how do I disable auto-defrag in Vista ?
I didn't see this option on the Tweaker,
I'm prepared to alter a registry value to switch auto-defrag off.
