Hi, I'm using Win 8 Release Preview Build 8400. I'm happy so far. But when I touch an app, it opens FULL screen. The only way I have found to get it closed is to open the Task Manager and End it. Anybody know a better way? Ctrl+Z or something? Thank you.

Mouse down to the bottom left corner of the screen
and click the menu button.
The application will go into a sort of standby mode
and doesn't use any CPU,but will still be ready when
you want to go back to it.

Thank you.

If you mouse up to the upper left corner of the screen a thumbnail of the last Metro app you launched will display. You can then right click it to get a close option. If you mouse up to that same corner, then move your mouse down the left side of the screen a bar will open with all the active Metro apps. Clicking its thumbnail/tile will switch you to that app. You can also close them from there.
