Important This update must be installed before you sync the upgrades classification. If the update is not installed when the upgrades classification is enabled, WSUS will see the Windows 10 build 1511 feature upgrade even if it can’t properly download and deploy the associated packages. If you try to sync any upgrades without having first installed KB 3095113, you will populate the SUSDB with unusable data that must be cleared before upgrades can be properly distributed. This situation is recoverable but the process is nontrivial and can be avoided altogether if you make sure to install the update before enabling sync of upgrades. If you have encountered this issue, refer to the following article:
For more information about Windows 10 servicing and how feature upgrades and servicing updates differ, see the following TechNet topic:
This update also fixes an issue in which Windows 10-based computers are displayed as "Windows Vista" on Windows Server 2012 R2 or Windows Server 2012.
