About this update


Subject Interface Packages (SIPs) are required in order to read the digital signatures on specific file types. After you install this update, SIPs enable the WinVerifyTrust function to handle a later version of Windows on the Microsoft Windows Server Update Services (WSUS) server. SIPs also enable down-level WSUS environments to read the new file types that can be used for upgrades in a later version of Windows.
