Note Windows Update will offer and install multiple packages under KB 2919355. However, there is only one KB 2919355 update entry in Programs and Features. You can also use the DISM command to verify the installation or removal of the update.

To determine whether the Windows RT 8.1 update or the Windows 8.1 update is installed on your computer, see Which Windows operating system am I running? (http://windows.microsoft.com/en-us/windows/which-operating-system) , and then expand the Check for operating system info in Windows 8.1 or Windows RT 8.1 section.
Windows Update
This update will be available from Windows Update (http://update.microsoft.com/) .

Notes
  1. This update is provided as an Important update.
  2. If you select the Install updates automatically (recommended) Windows Update setting, this update is installed automatically.
  3. If you select other Windows Update settings, we highly recommend that you immediately install this update through Windows Update.
  4. The MSDN and VLSC updated ISOs do not contain the complete set of fixes that are offered from Windows Update. Therefore, Windows Update and Windows Server Update Services (WSUS) will offer update 2919355 again to the computers that are deployed by using the images in these ISOs. This is expected and does not trigger the full reinstallation of the Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 update, but only one smaller component of it. The rest of the update will not be downloaded or reinstalled.
  5. Windows Update may offer this update again even when the computer already has this update installed. This is expected and intended to resolve a Windows Update client issue. Windows Update installs only package 2959977  (http://support.microsoft.com/kb/2959977/ ) . This resolves the Windows Update clients issue instead of all the packages included in this update.

You can also obtain the stand-alone update package through the Microsoft Download Center.
