it helps to know about this resource. Let me state up front that things have changed significantly in Vista around kernel address computer out of memory windows 10 space, and much of what I’m talking about today does not apply to Vista. Laying the groundwork: Session Space To understand desktop heap, you first need to understand https://social.technet.microsoft.com/Forums/windowsserver/en-US/14be2a9b-91d6-49ba-8926-4838a6e0e88d/high-io-write-in-windows-2003-server?forum=winservergen session space. Windows 2000, Windows XP, and Windows Server 2003 have a limited, but configurable, area of memory in kernel mode known as session space. A session represents a single user’s logon environment. Every process belongs to a session. On a Windows 2000 machine without Terminal Services installed, there is only a single session, and session space does not exist. On Windows XP and Windows Server 2003, session space always exists. The range https://blogs.msdn.microsoft.com/ntdebugging/2007/01/04/desktop-heap-overview/ of addresses known as session space is a virtual address range. This address range is mapped to the pages assigned to the current session. In this manner, all processes within a given session map session space to the same pages, but processes in another session map session space to a different set of pages. Session space is divided into four areas: session image space, session structure, session view space, and session paged pool. Session image space loads a session-private copy of Win32k.sys modified data, a single global copy of win32k.sys code and unmodified data, and maps various other session drivers like video drivers, TS remote protocol driver, etc. The session structure holds various memory management (MM) control structures including the session working set list (WSL) information for the session. Session paged pool allows session specific paged pool allocations. Windows XP uses regular paged pool, since the number of remote desktop connections is limited. On the other hand, Windows Server 2003 makes allocations from session paged pool instead of regular paged pool if Terminal Services (application server mode) is installed. Session view space contains mapped views for the session, including desktop heap. Session Space layout: Session Image Space: win32k.sys, session drivers Session Structure: MM structures and session WSL Session View Space: session mapped views, including desktop heap Session

This is for people with lots of ram that usually open many windows (or IE http://www.microsoftdll.com/fix-windows-error-the-desktop-heap-encountered-an-error-while-allocating-session-memory-there-is-more-information-in-the-system-event-log.php tabs for example) and seldom restart their notebooks. I use my 2GB ram a lot - I usually run multiple apps at once including Dreamweaver (likes memory and it has a out of memory leak btw), Fireworks, IE7 with 10+ tabs, Word (few windows), Access, WMP + usual stuff like Windows explorers, winrar, skype, gtalk etc... Now and then I also play games like fear and cs:s (steam). All in all I usually use around 1,5GB ram and I don't restart often, but put notebook to hybrid sleep instead. And it is used like that for weeks. out of memory It is a very good practice since comp wakes up in seconds with my programs already started and ready, but it has one disadvantage - it sometimes uses all of Windows Desktop Heap resources meaning sometimes I cannot open a new tab, start new app or even get a rightclick menu! I need to close some window in order to free some of the resources. If you go to the Event Viewer/System you would find something like this: "A desktop heap allocation failed". It has nothing to do with free ram! You can read an exellent article here: http://blogs.msdn.com/ntdebugging/archive/2007/01/04/desktop-heap-overview.aspx Microsoft KB: The system has run out of desktop heap. Every desktop object on the system has a desktop heap associated with it. The desktop object uses the heap to store menus, hooks, strings, and windows. The system allocates desktop heap from a system-wide 48-MB buffer. In addition to desktop heaps, printer, and font drivers also use this buffer.Click to expand... It happens on XP and Windows Server 2003 too. Vista is not an exception. 64 bit versions seem to have much more resources ready for allocation. So how to f
the system. Consequently the descriptions of these codes cannot be very specific. Use of these codes requires some amount of investigation and analysis. You need to note both the programmatic and the run-time context in which these errors occur. Because these codes are defined in WinError.h for anyone to use, sometimes the codes are returned by non-system software. Sometimes the code is returned by a function deep in the stack and far removed from your code that is handling the error. Error Mode The error mode indicates to the system how the application is going to respond to serious errors. Serious errors include disk failure, drive-not-ready errors, data misalignment, and unhandled exceptions. This error mode can be managed by either a per-thread or per-process basis. An application can let the system display a message box informing the user that an error has occurred, or it can handle the errors.

Repair tool from this link In this section Topic Description Assessment Execution Engine The Windows Assessment Execution Engine (AXE) enables the management and execution of Windows system assessments. Assessments can help a person understand the state of a system and remedy problems with performance, reliability, or functionality. AXE provides infrastructure needed to manage assessments using a UX tool or script, run assessments, make measurements, process raw data into results, run diagnostics, and publish the results. Debugging and Error Handling Describes debugging and error handling. Hardware Counter Profiling Applications use the Hardware Counter Profiling (HCP) SDK to capture thread profiling data such as cycle time and the reasons for context switches. You can also use HCP to capture counter data for hardware performance counters that you have configured on the system. Network Diagnostics Framework The Network Diagnostics Framework (NDF) provides a way for component and application developers to simplify network troubleshooting for users. Users can attempt to diagnose and repair a network problem using a single troubleshooting tool. Network Monitor Network Monitor captures network traffic for display and analysis. It enables you to perform tasks such as analyzing previously captured data in user-defined methods and extract data from defined protocol parsers. Performance Counters Counters are used to provide information as to how well the operating system or an application, service, or driver is performing. The counter data can help determ
