LM Hash is a place on your personal computer (PC) where the Microsoft Local Area Network (LAN) Manager places user passwords that are less than 15 combined letters, numbers and symbols, such as "tc87.lup3." LM Hash is typically found on Microsoft Windows 2000 and XP operating systems through the use of your registry editor. Finding your LM Hash on your PC allows you to enable or disable its password storage on your computer.
