    As a writer you should be familiar with the concept of "KISS". Most folk
    with problems of this sort are not as clued-up as you (nor as I). Most
    folk don't want to start digging into the configuration of start-up
    processes (and a lot of applications start processes and don't close
    them at termination).
    Try being a little more pragmatic and try writing with the reader's
    level of knowledge in mind (I thought it was one of the basic principles
    of professional writing).
    Rubbish. You're knowledge of Windows internals isn't as good as you
    appear to think it is.
    Rubbish again. You're knowledge of Windows internals *definitely* isn't
    as good as you appear to think it is.
    Wow... Where did you pick up the tekkie buzz words? You might impress
    the average reader here but you certainly don't impress me. But I
    suppose your impression is that you're impressing the non-technical here
    does wonders for your ego :)

    Incidentally, "heap" is not a Window term, rather "pool", but I'd better
    stop there in case anyone might think that I'm emulating your ego thing.

  2. All the insulting and stupid stuff snipped.

    All readers note that as per usual Mr Morgan doesn't actually address the points
    raised but like most pathetic and deeply sad people, he tries to attack using
    scant knowledge.
    You really don't know what you are talking about. Why not get yourself a starter
    teach yourself book about programming for microsoft windows.

    Direct quote from MSKB

    In Windows 95, Windows 98, and Windows Me, GetFreeSystemResources checks the
    percentage of free memory in the following five resource heaps:

    The 16-bit User heap (64K).
    The 32-bit User window heap (2MB).
    The 32-bit User menu heap (2MB).
    The 16-bit GDI heap (64K).
    The 32-bit GDI heap (2MB).

    I suggest that you go to MSDN and search for the word heap in the knowledge base
    but, of course, you wouldn't be able to understand the results.

    The following is just a small section from MSDN

    Memory and System Information

    In the memory allocation arena, Windows Server 2003 and Window XP have a feature
    called the low-fragmentation heap. This heap algorithm avoids fragmentation by
    allocating all blocks from 128 predetermined different block-size ranges, called
    buckets. When an application needs to allocate memory from the heap, the heap
    chooses the bucket that's able to hold the requested block with the least wasted
    space. The system uses the traditional heap for blocks greater than 16KB. To use
    the low-fragmentation heap, call HeapSetInformation, passing it the appropriate
    heap handle and flag value. All heaps default to "normal" Win32 heap behavior
    until HeapSetInformation is called. To determine which behavior a heap is using,
    call the HeapQueryInformation API.


    Built-in User Heap Leak Detection
    Windows XP provides built-in user mode heap-leak detection. Poorly written or
    miscoded applications can "leak" heap memory. In earlier versions before Windows
    XP, when this situation arose, special tools were needed on the server to help
    identify the cause of the memory leak. User mode component heap allocation leaks
    can be seen in two ways:


    Additional Heap Counters
    Another important new feature in Windows XP is heap performance monitoring.
    Performance Monitor (Perfmon) can display about 20 heap-related counters: amount
    of memory reserved and committed per heap, number of blocks allocated and freed
    for three class sizes, average allocated and free time, lock contention, and
    others. Perfmon will display these counters when the following registry key is

    There's plenty more. You really must write to Bill Gates and tell him to change
    all the windows documentation as "'heap' is not a Window term".

    Have you actually ever produced anything worthwhile, software or video?

    Why you make these pointless and fruitless attacks is beyond me. Maybe you have
    an ego problem, as far as I am concerned I do have some in depth knowledge of
    low level programming and, of course, film and video production. However,
    everyday I learn something new either by reading or more likely from people with
    more specialist knowledge - only today I learnt that locked audio in DVCAM is "
    is a combination of urban myth, inter company BS and some truth."

    I won't respond further to you. It's only worth arguing with open minded people.

    Then kill-file me :)
    Your loss, not mine...

    But please, please, don't continue to advise people to re-install their
    OS to fix their problems.

    LOL, now who is on the ego trip?
    I suspect Stuart McKears has forgotten more than you know, anyone who
    seriously suggests a lack of memory (even though it already has 512mb) and
    to run 'Endit All' before the computer has even got beyond the boot stage is
    seriously lacking in their own basic knowledge.
    Are you serious, never ?

    ...but you've just rubbished your very own words there, Tony.

    I was actually referring to the words "Fortunately, XP (which I run) is
    a rather more forgiving than pre-Win2k/XP" and the implication that it
    was OK.

    The fact that 2K/XP seamlessly drops into VM is, IMHO, a not a blessing
    in this context, but a distinct disadvantage where video work is
    involved. The application often continues running, but the results
    (typically dropped frames) are only apparent much later when the
    procedure has completed. I'd sooner know that something is wrong before
    I've waited for an hour or to find out.

    The implication that VM is acceptable is (again IMHO) flawed. It's great
    for things like WP, but for what is effectively real-time processing
    it's a disaster and to be avoided like the plague with video work.

    Anything you can do to avoid going into VM must be a "good thing" -
    especially when it takes only moments to do.

    But the sentence you're rubbishing was actually originally written by
    yourself - no? Maybe you should clarify how your own sentence has a
    bearing on the other poster's knowledge of Windows internals. I'm
    certainly confused...

  8. Now where do I live?
    With careful use of pre XP setup switches a re-install followed by an windows
    update is often a quick way to solve driver and hardware problems.

    AIUI, setup reorders the drivers, dlls, etc chain so that redundant drivers
    don't actually get called even though they still get loaded on boot - however,
    this is not something I can be categoric about especially as google doesn't
    return anything significant from my expected keywords!!
