Registry Tip : How large is my registry?
The amount of memory used by the registry footprint can be found by clicking on
Start/Settings/Control Panel/System icon/Performance tab/Virtual Memory Change.
You will see the amount of memory currently being consumed by your registry and
you can increase the maximum allowed in the same dialog box. Experimentation
with C2 settings will easily push you over this limit and you will need to
increase the maximum size allowed.
