For Windows 7 and Windows Server 2008 R2, the 3035131 update discussed in this bulletin shares affected binaries with the update being released simultaneously via Security Advisory 3033929. This overlap in affected binaries necessitates that one update supersede the other and in this case it is advisory update 3033929 that supersedes update 3035131. Customers with automatic updating enabled should experience no unusual installation behavior; both updates should install automatically and both should appear in the list of installed updates. However, for customers who download and install updates manually, the order in which the updates are installed will determine the observed behavior as follows:
Scenario 1 (preferred): Customer first installs update 3035131 and then installs advisory update 3033929.
Result: Both updates should install normally and both updates should appear in the list of installed updates.
Scenario 2: Customer first installs advisory update 3033929 and then attempts to install update 3035131.
Result: The installer notifies the user that the 3035131 update is already installed on the system; and the 3035131 update is NOT added to the list of installed updates.
