My data is gone. How do I recover it? First, don't panic, writes Bob Rankin. Data is incredibly durable and seldom unrecoverable. In fact, it's extremely difficult to erase data when you want to.

What to do about Windows Registry errors. (Another helpful article from Bob Rankin.) The Windows registry is a database of settings and options for Windows features, programs, data files, and computer hardware.
