This isn't so much a rustle of my jimmies, since it didn't happen to me, but a completely computer illiterate coworker's wife had her laptop fall prey to the Windows Bitlocker update fiasco. Try explaining to two people that barely know how to get to Facebook that their laptop is just a big paperweight unless they can figure out what email they used as their Microsoft account when they got the computer. I even offered to help them sit at a computer and try multiple different emails but apparently they are going to "figure it out" somehow. I hope they take it to Best Buy and get charged for the same advice.
Still, that is complete and utter horseshit that it even happened, and I'd be super pissed if it happened to me. I always set mine up without Microsoft accounts, and lately I've made sure Bitlocker is off, but can you even have that active without a MS account? That would mean it was literally unfixable if you didn't write it down somewhere.
