Legancy system

With Windows 95,Windows 98,Windows Me and windows NT,administrators can use a special file to be merged into the registry, called a policy file (POLICY>POL).The Policy file allows administrators to prevent non-administrator users from changing registry setting like ,for instance,the security level of Internet Explorer and the desktop wallpaper.the policy file is used in business with large no.of computers where the business needs to be protected from careless users.

The default extension for the policy file is .POL. The policy file filters the setting it enforces by user and by group(a "group"is a defined set of users). To do that policy file merges into the registry,preventing users from circumventing  it by simply changing back the setting. The policy file is usually distributed through a LAN,but can be placed on the local computer.

The policy file is created by a free tool by Microsoft that goes by the file name poledit.exe for Windows 95/98 and with a computer management  module for NT-based system.The editor requires administrative
permissions to be run on system that use permission.The editor can also directly change the current registry setting of the local computer and if the remote registry service is installed and started on another computer it can also change the registry on that computer.

The policy editor loads the setting it can change from .ADM files, of which one is included, that contains the setting the Windows shell provides. The .ADM file is plain txt and supports easy localization by allowing all the strings to be stored in one placed.
