7. Terrible things happen if you turn off your PC without shutting down Windows

30 iterations were run in an informal test, turning off a pair of systems running Windows XP without first shutting down Windows. Each time documents were left open in Word, Outlook, and Quicken. Even Internet connection was up and running.

After turning each PC back on, Symantec's Norton Disk Doctor were run and the Windows disk checker to see if the hard drive had suffered any ill effects. Applications were reopened that had been left running and Internet was reconnected.

And to everyone’s happiness, Disk Doctor found no disk errors.
