Known Issues in the Patch Tuesday Update

Problem 1

You may experience certain authentication issues in Internet Explorer 11 after installing KB4489899 Windows 10 1809. This specific problem may occur when two or more people use the same user account. When they use the same account for multiple, concurrent login sessions on the equal Windows Server machine. It also includes the Remote Desktop Protocol (RDP) and Terminal Server logons as well. So, the symptoms that users are confronting are as follows.

  • The size of the cache and location may display empty or zero.
  • Keyboard shortcuts may fail to function properly.
  • Webpages may fail to load or render correctly at irregular intervals.
  • Credential prompts may generate certain issues.
  • Problems when users make an attempt to download files.


You need to avoid people from sharing the same user account when logging on to a Windows Server machine. So, the best solution is to create unique user accounts. In addition, you need to disable multiple RDP sessions as well for a single user account for a particular Windows Server.

However, the team is working on a resolution and will shortly send it in the forthcoming updates.

Problem 2

You may also experience issues with audio output after installing KB4489899 Windows 10 1809. The problem will occur on the devices that have multiple audio devices. Here, the apps that provide advanced options for external or internal audio output devices may fail to function all of a sudden.

Some of the applications that may stop working are the Sound Blaster Control Panel, Windows Media Player (WMP), and Realtek HD Audio Manager.

You need to modify the output of the application to Default in the per-application audio settings. This is a temporary workaround and to do so,

  • Open Windows Settings and navigate to System.
  • Move to the sub-section Sound on the left sidebar of the following page. On the right pane, click the option “App Volume and device preferences“.
  • Here, for each application, change the output to Default.

  • Get access to Windows Media Player and click Tools. Choose Options followed by Devices.
  • Here, select the device and choose Properties.
  • Upon the prompt of the next dialog, click the drop-down menu below Select the Audio Device. From the options, select the Default Audio Device.
