pageheap [OPTION [OPTION ...]]

    /enable PROGRAM         Enable page heap with default settings.
    /disable PROGRAM        Disable page heap.
    /full                   Page heap for all allocations.
    /size START END         Page heap allocations for size range.
    /address START END      Page heap allocations for address range.
    /dlls DLL ...           Page heap allocations for target dlls.
    /random PROBABILITY     Page heap allocations with PROBABILITY.
    /debug                  Launch under debugger `ntsd -g -G -x'.
    /kdebug                 Launch under debugger `ntsd -g -G -d -x'.
    /backwards              Catch backwards overruns.
    /unaligned              No alignment for allocations.
    /decommit               Decommit guard pages (lower memory use).
    /notraces               Do not collect stack traces.
    /fault RATE [TIMEOUT]   Probability (1..10000) for heap calls failures
                            and time during process initialization (in second
                            when faults are not allowed.
    /leaks                  Check for heap leaks when process shuts down.
    /protect                Protect heap internal structures. Can be
                            used to detect random corruptions but
                            execution is slower.
    /no_sync                Check for unsynchronized access. Do not
                            use this flag for an MPheap process.
    /no_lock_checks         Disable critical section verifier.

PROGRAM      Name of the binary with extension (.exe or something else).
DLL          Name of the binary with extension (.dll or something else).
PROBABILITY  Decimal integer in range [0..100] representing probability.
             to make page heap allocation vs. a normal heap allocation.
START..END   For /size option these are decimal integers.
             For /address option these are hexadecimal integers.

If no option specified the program will print all page heap enabled
applications and their specific options.

The `/leaks' option is effective only when normal page heap is enabled
(i.e. not full page heap) therefore all flags that will force full
page heap will be disabled if /leaks is specified.

Note. Enabling page heap does not affect currently running
processes. If you need to use page heap for processes that are
already running and cannot be restarted (csrss.exe, winlogon.exe),
a reboot is needed after the page heap has been enabled for
that process.
