Remember that Windows Server 2008 R2 patches are also applicable and they are not included in this particular list.This method is the most demanding on your time and energy, but may be the only solution in cases involving Hyper-V installations that are completely isolated from any network connection.
Fortunately, most installations won’t need any hotfixes at all.
The patches that will be needed on every deployment can be downloaded and installed manually from the Download Center, managed by Windows Server Updates Services, or automatically handled by Windows Update.
Items marked with “hotfix” availability are not included in Windows Update, so you’ll need to manually acquire those if you meet the conditions in the “Required? The “Applies to:” column is actually more important than it might first appear.
Obviously, if you’re using Hyper-V R2 then you’re also using Windows Server 2008 R2.
In this context, its most important feature is fine control over which patches are allowed and when they are installed without requiring administrators to manually perform acquisition and installation.
