Oh... you're saying it would be better (in my case) to just encrypt a certain (non os partition/folder) of my HDD, and only mount it when in use, or use an external hdd/usb drive.
(though I don't thing Truecrypt supported thumb drives...)
Yes, that's it, far less overhead if you don't have much confidential data, and you can be selective on a file/folder basis.

I don't know about truecrypt, but I would have thought that it supported USB external drives?

Anyways, your thumb srive should come with security software pre-installed, if not there are loads of free ones available.

Obviously, as soon as you open stuff it becomes available, only less so if you are not connected to the internet.

There is a Registry setting to wipe the pagefile on shutdown. I believe it is only a single pass, but that should be adequate to deter remote attackers.

You might change your dump settings to only allow the minidumps. I don't think that they contain anything confidential?
