analyst found out.
RK: Joe, you'll love this.

JW: Hit me, Roger.

RK: I'm totally locked out of my Vista upgraded system—no way to even roll
it back. A Dell 1210 with 2BG of memory that I used an upgrade disk on.

JW: BitLocker?

RK: Nope. It says I didn't activate, that my key is already in use that I
only get reduced functionality. But it's not enough to even roll it back.

  ROFL - BitLocker?  Nope - Enhanced Reduced Functionality Mode.
