Consequences if program was ended by Task Manager

[Magnum]

I would like to plan for different possibilities that may occur when
a program is run.

What would happen to the O.S. if the program was ended by Task Manager? 

What other "collateral damage" could occur ?

What would happen to the O.S. if the program was ended by Task Manager?

On win XP ,vista,win 7 ,NOTHING
For the program,all data can be lost.

So, are you saying that only my keyboard shortcuts would be lost?

All things installed by your program would be lost (keyboard shortcuts,...),YES
