Probably the #1 most useful shortcut in Windows has always been Alt + Tab, Tab, Tab, which lets you switch quickly from one running program to another to another. But for some reason, Microsoft nearly ruined it in Windows 7. If you hesitate for a few seconds with your thumb on the Alt key after pressing Tab once or twice, the pop-up window that shows the list of running programs disappears, and you see one of the programs. And then you can’t prevent it from happening. Microsoft actually considers this a feature! They call it “Aero Peek”.
Here’s how to disable it and make Alt + Tab work like it did in previous versions:
- Press + Pause/Break to display System Properties.
- Click Advanced System Settings on the left.
- In the Advanced tab, in the Performance section, click Settings (i.e. the first Settings button).
- This displays the Performance Options dialog. In the Visual Effects tab, deselect Enable Aero Peek.
- Click OK twice to close the two dialog boxes, then close the System Properties dialog.
An alternative is to completely ignore this and use the + Tab shortcut, instead. It presents you with a 3-D stack of windows that you can cycle through. It looks cooler than the Alt + Tab window, but I often find it hard to tell which window is which.
