I'm a big fan of Aero Shake but my favourite is Aero Peek (gives you the ability to see the application window for a given application when you either alt-tab (and wait) or move the mouse over the task bar thumbnail) and you need Aero Peek to be on (see screen shot)

And the screen shot below is Aero Peek working ... just love it ! :D

I use it all the time. It is one of the best features of Windows 7.

I really like the jump list feature in windows 7. It is a new UI feature that shows a list of recently opened files in that application. Right click on the icon on your taskbar and you will see a list of recent files for that program. Alternatively, click on the taskbar item and hold the click down while simply moving the cursor up.

That's one of my favorites also. I also like the ease in switching to open windows when you have more than one open in a group. Also easy to close windows you don't need any longer.

I like the "Blue Screen of Death". It's kind of exciting to have this feature since you never know when it will happen.

So rigt with any version prior to XPO. Now things are stable since more time is spent developing drivers which was the cause of the problem.

I like the convenience of jump lists, These context-sensitive Taskbar menus let you start accomplishing things in applications before you even open them.

 

 

also Windows 7's version of the Taskbar is less cluttered than Vista's, and it handles both running and nonrunning apps with not a problem, and quicker taskbar views where you can see everything at once.

 

new versions of Windows have gobbled up twice the amount of CPU power and RAM that their predecessors did. But Windows 7 runs a bit better than Vista on the same system too.

My favorite is the snipping tool.
