    MEMORY LEAK after cumulative updates?


    I know what I'm going to suggest isn't an obvious thing around here. So I have to first explain my perspective on RAM before I can even talk about a 'memory leak' or what might be called 'RAM hogging'.

    In Windows 10 I know of two places I can check RAM usage. Task Manager and Resource Monitor. If I do a fresh boot and open Firefox with a handful of tabs, I get this from Task Manager --

    But if I open Resource Monitor I see this --

    See that blue line of 'standby' RAM? I know there are people who will swear up and down and left and right that standby RAM isn't really used RAM at all. That it's 'reserved' to help my open apps run better.

    Perhaps it is but I can assure you of this -- once that blue line grows to take up the remaining available 'free' RAM... the system starts acting buggy. Typing in Firefox suddenly goes to a crawl.

    How do I know this? Whenever typing goes to a crawl I open resource monitor and, sure enough, that blue 'standby' RAM has filled everything up. And the issue goes right away with a reboot.

    I find that it usually takes about 4 or so hours for that blue line to eat up the remaining free RAM. Until recently when it expands seemingly much faster. So much faster I call it a 'memory leak'. If that is not the right term for this I kinda don't care because that's the experience of it. Either the system or an app is munching up RAM out of normal parameters.

    So now that this has been explained do you experience this? Do you think it's Firefox or a recent system update?

    :)

    Memory leak issue

    The term "memory leak" means that an application fails to return all its RAM to the operating system when it exits. The leftover RAM is unusable to the operating system.

    Step one is to identify the application that is leaking memory. Step two is to contact the application's developers and provide as much detailed data on the memory leak as you can. For example: which processes are still in RAM after the application exits
    and how much RAM they occupy. Application developers never want their applications to leak memory and they will be grateful for the details you provide, particularly if they can replicate the leak on their own computers.

    Possible Memory Leaks in Windows 10

    A memory leak occurs when an application closes and fails to release all its RAM back to the operating system.

    The first step in dealing with a memory leak is to determine which application is leaking memory.

    The next step is to contact that application's technical support with complete details of the memory leak, since the developers will want to fix the problem ASAP.

    MEMORY LEAK after cumulative updates?

    HidBthLE.dll - memory leak

    Well, looking into it, it seems that on my Win8 system (that has all published fixes and updates installed) the Bthleenum.sys is from July 2012, whereas the cumulative update for Win10 carries a version from 05/Jan/2016.

    So obviously no fixes for Win8 so far. In that case, my questions are:

    • Does the new Bthleenum.sys version fix the memory leak on Win10?
    • If it does, can someone at Microsoft publish the fixes for Win8?
    • In the meantime, can I extract Bthleenum.sys from the cumulative update package and simply use it as-is on my Win8 system? Is there some process that I need to go through to perform the update? Do I need to extract any of the accompanying files along with
      it (e.g. Bthenum.sys, Bthmini.sys, Bthport.sys, Bthusb.sys)?
