I'm sure there are exceptions. But when you get on a plane, by default, assume that the window armrest won't move.
Most of them are bolted to a bracket.
I HAVE seen MANY an armrest where Passenger XYZ has decided to MAKE the window armrest go up.
The carrier I work with spends lots of money replacing shattered aluminum brackets as a consequence.

Haha. Thanks for the info. Maybe it's a sign that carriers should make those armrests raiseable!
