Enabling Policy "Deploy default Accelerators" in Internet Explorer causes profile data to not be deleted at logoff


Symptoms

Consider the following scenario. You have configured roaming profiles in Internet Explorer 8, which you expect should be deleted after a user logs off. 
When you enable the policy "Deploy Default Accelerators", the Accelerators are deployed, but when a user logs off, the profile cannot be unloaded completely.

Cause

When the Accelerator is deployed it typically includes a path for its icon-file for the given server, for example http://www.bing.com/favicon.ico . During the deployment this icon-file is downloaded within winlogon.exe. The download itself initiates open file handles to Cookies, Temporary Internet Files and History. These handles will stay open when the user logs off, and therefore winlogon.exe cannot remove the profile completely.

Resolution

Download the icon-file manually and store it on a file server. Then, edit the XML file of the Accelerator and change the location in the <icon>-tag to point to the file share.

Following is an example with the Accelerator of Bing Maps:


This is the section of the original Accelerator which you plan to deploy, and which you have saved to a UNC location, for example \\server\share\accelerator\bing-maps.xml:

<display>
<name>Bing Maps</name>
<icon>http://www.bing.com/favicon.ico</icon>
</display>


1. Download http://www.bing.com/favicon.ico and save it to \\server\share\accelerator\bing.ico
2. Modify your accelerator file accordingly:

<icon>\\server\share\accelerator\bing.ico</icon>
