YesWindows Updates types
There are two major types of Windows Updates:-
GDR - General Distribution Release.
A binary marked as GDR contains only security-related changes that have been made to the binary, including changes that are relevant to this build of the file and those from any earlier security hotfix that updates the same binary.
These updates are distributed via Microsoft WSUS.
-
LDR (QFE) - Limited Distribution Release (formerly known as Quick Fix Engineering).
A binary marked as QFE/LDR contains both security-related changes that have been made to the binary as well as any functionality changes, including changes that are relevant to this build of the file and those from any earlier security fix or bug fix that updates the same binary.
These updates are installed manually and are not present in WSUS.

Windows Updates Mechanism
As of Windows 2008, binary files of an update are unpacked under the "\Windows\WinSxS" folder, after which a hardlink to the actual "location" of the file is created.
