Known issues in this update


Symptom Workaround

After installing this update, Internet Explorer 10 may have authentication issues. This occurs when two or more people use the same user account for multiple, concurrent login sessions on the same Windows Server machine, including Remote Desktop Protocol (RDP) and Terminal Server logons. Symptoms reported by customers include, but may not be limited to:

  • Cache size and location show zero or empty.
  • Keyboard shortcuts may not work properly.
  • Webpages may intermittently fail to load or render correctly.
  • Issues with credential prompts.
  • Issues when downloading files.

Create unique user accounts so that two people don’t share the same user account when logging on to a Windows Server machine. Additionally, disable multiple RDP sessions for a single user account for a specific Windows Server.

Microsoft is working on a resolution and will provide an update in an upcoming release.

After installing this update, MSXML6 causes applications to stop responding if an exception was thrown during node operations, such as appendChild(), insertBefore(), and moveNode().
