Thank you PowerShell team, thank you quest!!!
Long story short, I tapped the up arrow one too many times. Had I not tacked on a last second -whatif. I would have reset the password on 20,000+ user accounts. OUCH!
Tack it on early and often! No matter how comfortable you may be. The truth is PowerShell is so damn powerful it must be treated with great respect, and a small amount of fear. Mistakes here can REALY mess stuff up. The PowerShell team gave us the tools to cover our butts, use them!
