Issue 1A Windows 8-based or Windows Server 2012-based computer experiences high CPU usage when it runs a Windows Update applicability scan. Additionally, the applicability scan takes longer than expected.
Issue 2Duplicate entries are logged in the CBS log file when the Windows 8-based or Windows Server 2012-based computer runs an automatic Windows Update applicability scan.
Note The path of the CBS log file is C:\Windows\Logs\CBS\CBS.log.
Issue 3Consider the following scenario:
- You start Windows Internet Explorer on a Windows 8-based or Windows Server 2012-based computer.
- You install the Microsoft update for Adobe Flash Player in Internet Explorer (update 2755399).
- You perform either of the following operations:
- You install an update that contains drivers.
- You install an update that does not contain drivers, and then you install an update that contains drivers.
- You install another update, and then you restart the computer.
Issue 4When you install all the latest driver updates on a computer that is running Windows 8 or Windows Server 2012, certain system drivers (for example, Acpi.sys) in the following location are not updated:
Issue 5Assume that you try to install a servicing update on a computer that is running Windows 8 or Windows Server 2012. If the servicing update contains a driver update (especially an audio driver update), the servicing operation fails, and you cannot install the servicing update.
Issue 6Assume that several updates cannot be installed because of a failure that relates to one of these updates on a computer that is running Windows 8 or Windows Server 2012. In this situation, the other updates that are installed bundled with this update cannot be reinstalled even when the failure is resolved. If you try to reinstall the other updates, you receive a "CBS_E_SOURCE_MISSING" error message.
Issue 7Assume that you try to install the Application Server role together with Microsoft SharePoint or an independent software vendor customer application on a Windows Server 2012-based computer. In the case of certain timing conditions, the installation operation fails, and then it rolls back and restarts in an infinite loop.
Note The Application Server role is installed by using the Add Server Role Wizard or the Deployment Image Servicing and Management (DISM) tool.
Issue 8When an update for a "Features on Demand" Windows feature (for example, the .NET Framework 3.5) is already installed on a computer, the feature cannot be enabled.
Note Windows 8 and Windows Server 2012 have the .NET Framework 3.5 disabled by default.
