Right-click your new "drive.exe" taskbar button, then right-click its file name and select Properties. Change the contents of both the Target and Start In boxes to point at the drive or folder of your choice, perhaps click Change Icon to choose an appropriate drive icon, and you're done - that drive or folder is now available at a click.

39. Expand your taskbar previews
Move your mouse cursor over a Windows 7 taskbar button and you'll see a small preview of the application window. To make this larger, launch REGEDIT, browse to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Taskband, right-click in the right hand pane and create a new DWORD value called MinThumbSizePx. Double-click this, choose the Decimal option, set the value to 350 and reboot to see the results. Tweak the value again to fine-tune the results, or delete it to return to the default thumbnail size.

40. Hiding the Windows Live Messenger icon
If you use Windows Live Messenger a lot, you'll have noticed that the icon now resides on the taskbar, where you can easily change status and quickly send an IM to someone. If you prefer to keep Windows Live Messenger in the system tray, where it's been for previous releases, just close Windows Live Messenger, edit the shortcut properties and set the application to run in Windows Vista compatibility mode.
41. Customise UAC
Windows Vista's User Account Control was a good idea in practice, but poor implementation put many people off - it raised far too many alerts. Fortunately Windows 7 displays less warnings by default, and lets you further fine-tune UAC to suit your preferred balance between security and a pop-up free life (Start > Control Panel > Change User Account Control Settings).
42. Use Sticky Notes
The Sticky Notes app is both simpler and more useful in Windows 7. Launch StikyNot.exe and you can type notes at the keyboard; right-click a note to change its colour; click the + sign on the note title bar to add another note; and click a note and press Alt + 4 to close the note windows (your notes are automatically saved).
43. Open folder in new process
By default Windows 7 opens folders in the same process. This saves system resources, but means one folder crash can bring down the entire shell. If your system seems unstable, or you're doing something in Explorer that regularly
