The Policies subkey stores registry entries that Group Policy manages.
Group Policy adds, deletes, and changes the values of entries in this subkey when you use the Group Policy snap-in to enable or disable a policy. When the policies affecting a particular user or computer change, such as when the user moves to a new user group, Group Policy deletes the entries for the old group and adds the entries for the new group.
Group Policy manages registry entries in four Policies subkeys:
The Policies subkeys in HKCU store policy-related entries that are configured separately for each user. Group Policy adds these entries when you enable (and, for some policies, when you disable) a policy in the User Configuration folder in Group Policy.
The Policies subkeys in HKLM store policy-related entries that apply to all users of the computer. The system adds these entries when you enable (and, for some policies, when you disable) a policy in the Computer Configuration folder in Group Policy.
Many policy-related entries can appear in both HKCU and HKLM. Typically, the entries in HKLM override the entries in HKCU when both are configured.
The SOFTWARE\Microsoft\Windows\CurrentVersion\Policies subkey stores policy-related entries for Windows 2000 and for Windows NT 4.0 and earlier. The SOFTWARE\Policies subkey is new in Windows 2000. Different versions of Windows support different policies.
To add, remove, or change the value of entries in this subkey, use Group Policy.
Many of the entries in the Policies subkeys have counterparts in other registry subkeys. These counterparts, known as "preferences," have the same effect on user or computer features as entries in the Policies subkey. However, when an entry appears in the Policies subkey, the preference is almost always ignored. For details, see the entry descriptions.
For detailed information about particular Group Policy settings, see the Windows 2000 Resource Kit Group Policy Reference.
For general information about Group Policy, see Windows 2000 Server Help or Windows 2000 Professional Help.
To see a table associating policies with their corresponding registry entries, see the Group Policy Registry Table .
Do not use a registry editor to change the values in the entries of this subkey. If you do, they will be overwritten the next time your policies are refreshed.
