Microsoft Dynamics CRM 2011, related Microsoft Windows Internet Explorer memory leaks, and Windows / Microsoft Update

You may have noted that Microsoft Dynamics CRM Sustained Engineering has released fixes for Internet Explorer-related memory leaks affecting our Microsoft CRM 2011 web client.  I've noticed that occasionally IE clients may still leak memory, eventually resulting in slower page load times or Out Of Memory errors, even though the latest CRM 2011 Update Rollup has been installed on your CRM servers.

Please note: Windows client servicing, via Windows Update or WSUS (Windows Server Update Services) + SCCM (System Center Configuration Manager) is also vital.  We've identified a fix that can potentially help with Internet Explorer memory leaks.  This fix was pushed through Windows Update via MS10-090: Cumulative security update for Internet Explorer.  It was released earlier this year and is likely already on your client machines.  HOWEVER: the fix I'm referencing here is registry enabled, so to receive the benefits of this fix, you need to add the registry keys mentioned in the associated Microsoft Knowledge Base article:

KB 975736: A memory leak occurs when you open a Web page that contains a circular reference in an iframe

The registry changes needed to activate the fix are described in this Knowledge Base article, and for large enterprises, these registry keys are generally pushed by GPO (Group Policy Objects) or other means.

In any case, I heartily recommend that you assure MS 10-090 is installed on your client machines and the KB 975736 fix enabled if you are still experiencing Internet Explorer-related memory leaks when the latest CRM 2011 Server Update Rollup (as of this writing, Update Rollup 5) is installed.

    Hello all,

    Thank you for this post, memory leaks in IE is something I have came across a few times in some computers, and generally i can get it solved by doing a simple "Reset Internet Explorer Settings", but of course there are a few exceptions and maybe this information will help me solve those cases.

    I would like to ask a question: Is this fix IE version independent?

    Keep up the good work!

    In KB-Article it says I should replace

    <appname>.exe when IE8 or 9 but there is no mscrm.exe. So what registry key to set?
