Windows 10 SDK Preview Build 14965 Released

Windows 10 SDK Preview Build 14965 Released

Today, we released a new Windows 10 Anniversary SDK Preview to be used in conjunction with Windows 10 Insider Preview (Build 14965 or greater). The Preview SDK is a pre-release and cannot be used in a production environment. Please only install the SDK on your test machine. The Preview SDK Build 14965 contains bug fixes and under development changes to the API surface area. If you are working on an application that you need to submit to the store, you should not install the preview.

The Preview SDK can be downloaded from the developer section on Windows Insider.

For feedback and updates to the known issues, please see the developer forum.  For new feature requests, head over to our Windows Platform UserVoice.

Things to note:

• The SDK will require Visual Studio 2017 Preview. You can download the Visual Studio 2017 Release Candidate here.

What’s New

• This Windows SDK includes updates and additions to the Windows namespace. See section API Updates and Additions below for the list.
• Debugging Tools for Windows has been updated with a few new features, including JavaScript scripting and extensibility. See the blogpost at https://blogs.msdn.microsoft.com/windbg/2016/10/27/new-insider-sdk-and-javascript-extensibility/ for more information.

Known Issues Windows SDK

• Wrong GenXBF.DLL
  If you installed a previous Windows SDK flight, either version 14951 or 14931, you may have an incorrect GenXBF.dll installed. Please follow the following steps after installing the Windows 10 SDK Preview build 14965.

1. Exit Visual Studio
2. Open an Administrative command prompt
3. Type the following:

   DEL “c:Program Files (x86)Windows Kits10binx86genxbf.dll”

   DEL “c:Program Files (x86)Windows Kits10binx64genxbf.dll”

4. Run Control Panel
5. Select Uninstall a Program
6. Highlight Windows Software Development Kit – Windows 10.0.14965.1000
7. Click Change
8. Select Repair
9. Click Next

Windows SDK setup will restore the missing GenXBF.dlls  with the appropriate version.

• Visual Studio 2017 fails with HRESULT: 0x80041FE2 when trying to create C++ UWP apps targeting build 14965 SDK

This is a known problem. Here are steps to address this issue in your project file:

1. Close the project
2. Open up the project file in notepad or your favorite editor
3. Add the following to the project file:

   <PropertyGroup><DoBundleInstallationChecks>false</DoBundleInstallationChecks></PropertyGroup>

4. Reopen the project in Visual Studio

Known Issues Microsoft Emulator

Microsoft Emulator Preview for Windows 10 Mobile (10.0.14965.0) crashes when launching

Impact:

Please note that there is a bug impacting the usage of hardware accelerated graphics in the latest release of the Mobile Emulator. Follow the instructions below to temporarily disable hardware accelerated graphics in the emulator and use the emulator with software rendered graphics (WARP).

NOTE: The following registry setting will impact any and all Microsoft Emulators installed on your machine. You will need to remove this registry setting in order to re-enable hardware accelerated graphics in the emulator.

1. Create the following registry subkey if it doesn’t exist: HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftXde10.0
2. Right click the 10.0 folder, point to New, and then click DWORD Value.
3. Type DisableRemoteFx, and then press Enter.
4. Double-click DisableRemoteFx, enter 1 in the Value data box, select the Decimal option, and then click OK.
