Snapshot button in Acrobat X

I recently updated to Windows 7 on a new computer. everything is new, sometimes means frustrating. Probably it is true that we are involved in the Micro-Intel robbing game by the never stopping updating...

any complaints do not change the world. so the trouble is the Acrobat X. i can not find the familiar Snapshot (the camera) button . it really waste me a long time (Damn, or TNND in mother language). here is the solving method - simple?! (just not understanding what the software updating pig-head thinking).

right click the tool bar --> Edit -->Snapshot
