No it's not possible, because you need drivers to intercept the disk traffic and decrypt/encrypt it.
You also can't mix EETech and Wintech on the same CD, because the drivers are different.
Im sitting at a Winpe command prompt. I cant kick off a script that loads all the eetech 6.1.3 drivers and launches wintech ?
There's gotta be a way to do this.
Not in windows - you can't dynamically load a filter driver - it has to be hooked in as the OS builds out the driver stack.
And, WinTech is incompatible with the v6 drivers - you need to stick to one version or the other, you can't mix them up.
