I installed so many Windows XP systems back in the day (manually of course) that I memorized the product key.

I still have a windows 98 first edition key memorized. And 26 digits of Pi. But recently I forgot the 4 digit PIN for my debit card and required a reset.

If Microsoft had panache they'd release a final Windows XP ISO that would only take that key.
