In some cases, the Windows 10 causes crashes or other issues when it calls the CreateWindowEx function in some 32-bit applications. We are aware of issues that affect some Microsoft Visual Studio extensions and the Bloomberg Professional service.

To determine whether your system is running Windows 10 Fall Creators Update (Version 1709, build 16299.19 or 16299.15), select Start, select Settings, select System, select About, and then look under Windows specifications for the Windows version information.


To work around this issue, roll back your Windows 10 installation to the previous version.

The roll back option is available for 10 days after you’ve upgraded your Windows 10 installation. To roll back, select Start, select Settings, select Update & Security, and then select Recovery. This keeps your personal files, but removes applications and drivers that were installed after the upgrade, and also reverses any changes that you made to settings.

If the roll back option isn't available, please contact your IT support or helpdesk for help to restore the computer to the previous Window 10 version.

We recommend that you make a backup of your personal files before you contact your IT support, helpdesk, or Microsoft Support.


Microsoft is working on a resolution and will provide an update in an upcoming release.
