Windows Server with SP1, Windows Server and Windows XP: There are no explicit limits on the total amount of space that may be consumed by hives in paged pool memory and in disk space, although system quotas may affect the actual maximum size.

The maximum size of the system hive is limited by physical memory as shown in the following table. Registry data is stored in the paged pool, an area of physical memory used for system data that can be written to disk when not in use. The RegistrySizeLimit value establishes the maximum amount of paged pool that can be consumed by registry data from all applications. This value is located in the following registry key:.

By default, the registry size limit is 25 percent of the paged pool. The default size of the paged pool is 32 MB, so this is 8 MB. If the value of this entry is greater than 80 percent of the size of the paged pool, the system sets the maximum size of the registry to 80 percent of the size of the paged pool.

This prevents the registry from consuming space needed by processes.
