The International subkey in the Policies subkey contains entries that store Group Policy settings for calendar options in Regional Options in Control Panel. The entries in this subkey are created and maintained by Group Policy and read and interpreted by Regional Options.
There is also a Regional Options setting for the desktop in Group Policy in HKCU\Software\Policies\Microsoft\Control Panel\Desktop.
The policy-related entries in the International subkey take precedence over non-policy related entries in the International subkey in HKCU\Control Panel\International.
For detailed information about particular Group Policy settings, see the Group Policy Reference (Gp.chm) on the Windows 2000 Resource Kit companion CD.
For general information about Group Policy, see Group Policy in Windows 2000 Help.
