The Registry Capacity Property
The rgy_edit properties command lets you set a limit on the number of entries that the local registry can contain. For example, assume that the registry capacity is set to 10 and that the registry contains 10 entries. If a new user logs in from the local machine, an entry is created for that user. This new entry overwrites the oldest of the original 10 entries. As users log in from the machine for the first time, their newly created registry entry overwrites the oldest entry.
