There is practically no limit to the things you can pin to the 

task-bar: 

often-used folders, the Control Panel, even a button to shut 

down your PC. (For the last option, find shutdown.exe in the 

System/Windows32 directory, create a shortcut to it, and then 

append this text to the target in Properties: /s /f /t 00).

You can access the Jump Lists by right clicking on any icon 

in the taskbar. You’ll find recently used documents, along 

with certain app-specific functions (such as setting your 

IM client to ‘Away’). One little time-saver: You can pin a 

Web URL to your browser’s Jump List by dragging that URL to 

the browser icon in the taskbar (do this by clicking on the 

mini icon in the URL bar).
