A customer still using Windows Server 2008 R2 to publish applications via RemoteApp reports the problem described on page https://support.microsoft.com/en-hk/help/981156/remoteapp-applications-are-displayed-as-black-windows-when-you-restart
They attempted to download the hotfix suggested in the page (Windows6.1-KB981156-v2) but it is not available anymore.
They can download it from third party sites but they are not sure it is genuine Microsoft software.
How can they get the hotfix from Microsoft?
Is there any alternate solution to fix their problem?
Regards
Mario
