Microsoft is finally getting serious about USB flash drive security. It recently disabled the AutoRun and AutoPlay features in Windows (all older versions plus Windows 7), meaning users will no longer have directory trees and execution options presented when they pop a flash drive into a PC. More significant, though, is Microsoft adding flash drive encryption to Windows 7. Through a few, albeit not so simple steps (see below), users can encrypt and manage the files on these small, portable storage devices.
