Windows 7 is notorious for always preparing to do something.
Preparing to download updates.
Preparing to install updates.
Preparing to restart machine.
Preparing to remove device.
Preparing to install device.
JFC! Just do it already. Stop preparing.
This is one of the most stark contrasts between XP and 7. XP didn't waste time preparing to do something, it just did it. In 7 you might as well go get lunch because it takes so long to do anything (or find anything for that matter because things are deliberately hidden.)
