The MSXML Components Use Too Much Memory in Windows CE .NET 4.2 (821039)


The information in this article applies to:

  • Microsoft Windows CE .NET 4.2

SYMPTOMS

The following problems occur in Windows CE .NET 4.2:
  • The Microsoft XML (MSXML) Document Object Model (DOM) and the XML minimal parser consume up to 100 kilobytes (KB) more RAM than they require for operation.
  • Programs that use MSXML on Windows CE .NET 4.1 do not work on Windows CE .NET 4.2.

CAUSE

The first problem that is described in the "Symptoms" section occurs because memory allocations for an unused garbage-collection feature of the XML minimal parser were left in place. These memory allocations consume 100 KB of RAM unnecessarily. Also, a private heap manager for XML DOM that is faster than the Microsoft Windows CE heap manager is used. The private heap manager is less efficient in terms of RAM usage, and can consume up to an extra 40 KB for simple parsing tasks.

The second problem that is described in the "Symptoms" section occurs because an inadvertent change to a GUID causes problems with backward compatibility with Windows CE .NET 4.1 XML.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

MORE INFORMATION

After an original equipment manufacturer (OEM) applies this hotfix, the OEM can select the heap manager that is used by XML DOM. To do so, the OEM can use a new registry setting. The OEM can set the following value to use the Windows CE heap manager instead of the XML custom manager:

[HKEY_CURRENT_MACHINE\Software\Microsoft\MSXML]
"MiniHeap"=dword:1

To address the GUID issue after applying this update, the OEM can add the following information to the Windows CE registry (for example, in the Public\Ie\Oak\Files\Ie.reg file):

[HKEY_CLASSES_ROOT\CLSID\{F6D90F11-9C73-11D3-B32E-00C04F990BB4}]
@="XML DOM Document"
[HKEY_CLASSES_ROOT\CLSID\{F6D90F11-9C73-11D3-B32E-00C04F990BB4}\InProcServer32] @="msxml3.dll"
"ThreadingModel"="Both"
[HKEY_CLASSES_ROOT\CLSID\{F6D90F11-9C73-11D3-B32E-00C04F990BB4}\ProgID]
@="Msxml2.DOMDocument"
[HKEY_CLASSES_ROOT\CLSID\{F6D90F11-9C73-11D3-B32E-00C04F990BB4}\TypeLib]

[HKEY_CLASSES_ROOT\CLSID\{F6D90F11-9C73-11D3-B32E-00C04F990BB4}\Version]
