A Windows Password Reset Recovery Disk (for Windows 7 and 8) is a bootable disc (CD, DVD, or USB drive) that you create *before* you lose your password. It contains tools that allow you to reset your Windows administrator password if you forget it, thus regaining access to your computer. It doesn[SQ]t work if you[SQ]ve already forgotten your password; it must be created beforehand. Essentially, it[SQ]s a preventative measure, not a solution for an already-existing problem.
