%1 -- Use CA's registry key
%2 -- Use CA's restore registry key
%3 -- Use policy module's registry key
%4 -- Use first exit module's registry key
%5 -- Use template registry key (use -user for user templates)
%6 -- Use enrollment registry key (use -user for user context)
%7 -- Use chain configuration registry key
%8 -- Use Policy Servers registry key
%9 -- Use policy or exit module's ProgId (registry subkey name)

RegistryValueName -- registry value name (use "Name*" to prefix match)
Value -- new numeric, string or date registry value or filename.
    If a numeric value starts with "+" or "-", the bits specified
    in the new value are set or cleared in the existing registry value.

    If a string value starts with "+" or "-", and the existing value
    is a REG_MULTI_SZ value, the string is added to or removed from
    the existing registry value.
    To force creation of a REG_MULTI_SZ value, add a "
" to the end
    of the string value.

    If the value starts with "@", the rest of the value is the name
    of the file containing the hexadecimal text representation
    of a binary value.
    If it does not refer to a valid file, it is instead parsed as
    [Date][+|-][%11] -- an optional date plus or minus optional
    days and hours.
    If both are specified, use a plus sign (+) or minus sign (-) separator.
    Use "%10+%11" for a date relative to the current time.

Use "%7\%12 @%10" to effectively flush cached CRLs.
