Customize your system tray

Customize your system tray.
These tips apply primarily to Windows 7

Windows 7 helpfully decreases the amount of space dedicated to 

the Notification Area by putting all but the most essential 

notifications within a drop-down (or, in this case, drop-up) 

box. It looks nice, but you can burn lots of time with wasted 

clicks as you hunt for what you need. If you want regular, 

click-free access to some of these notifications, change the 

default layout. It’s easy to do. Just open the tray’s spillover 

window and drag the icons you want to the taskbar area. You can 

rearrange icons within the added window, too.

But what if you like Aero Snap? Here is a faster way to snap 

windows right or left by using keyboard shortcuts instead of 

the mouse.  snaps left, and  snaps right. While we’re at it,  

will maximize your window, while  will minimize it. 

(Note, however, that if you have done the Registry hack 

described in the preceding tip to turn off Aero Snap, that 

hack will have disabled these particular shortcuts, too.)
