Microsoft Windows contains a super-user account called Administrator. It is often hidden from the common user (XP, Vista). Certain tasks may be "run as Administrator" in order to escalate a local user's rights temporarily. Because an administrator password is generally set when a computer operating system is first installed, and a lower-privileged account is used for day-to-day tasks, a user
. may forget the password for the Administrator account. In that case, it may be necessary to reset it manually. This is a potentially complicated process and is not without its pitfalls.
