IE 10 authentication issues

The installation of the update might trigger authentication issues for IE 10. The issue arises if the same account is being used by two or more users on a Windows Server system.

Some of the issues that you might face after the installation are:

  • Keyboard shortcuts fail to work
  • zero or empty location and cache size
  • File download issues
  • credential prompts bugs
  • Webpage loading issues

Microsoft stated that if you are using a Windows Server machine, the problem can be resolved by creating a unique user account.
