My wife, handier with money, loves leaving the num lock on.
I, handier with prose and software coding, want it off. (In fact, I always set the BIOS default to off on any computer).
Our kids could go either way, and have complained about it not being “right” when they switch user.
But since I moved our family PC to Windows 10 a couple months ago, I noticed it remembers each users’ last num lock setting. Hey cool! …But Google admits no knowledge of this feature. Am I just the lucky first guy to notice?
Regardless, this is another fine UI touch that Windows has invented in the last 5-10 years.
(Now if OS X would just get off their laurels and notice/copy them — oh hey Aero Snap anyone?)
