Abstract: A Skype for Business (=SfB) Windows client shows a black screen during screen sharing or crash during a screen sharing.
If a SfB user share his screen it shows a black screen (sometimes the remote side can see the mouse moving) or sometimes the SfB client crash after some minutes the SfB user shared his screen. Microsoft provided an hotfix for the issue which is mentioned here. However it looks like for many users the hotfix isn´t solving the issue.
A possible workaround is to upgrade SfB to the version 16.0.6741.2025 (make also sure you are using the latest driver). However this didn´t solve the issue for every user yet. So the current workaround for that issue is
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Lync]
"EnableP2PScreenSharingOverVideo"=dword:00000000
Additionally, if you use the 32-bit version of Skype for Business 2016 on a 64-bit operating system, add the following subkey:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\16.0\Lync]
"EnableP2PScreenSharingOverVideo"=dword:00000000
The keys above will disable Video Based Screen Sharing (VBSS) and then re-enable Microsoft Remote Desktop Protocol (RDP)-based screen sharing (which was used in the former version).
Note:
If the issue happen during a conference, then try the following key as an workaround:
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Lync]
"EnableConferenceScreenSharingOverVideo"=dword:00000000
Additionally, if you use the 32-bit version of Skype for Business 2016 on a 64-bit operating system, add the following subkey:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\16.0\Lync]
"EnableConferenceScreenSharingOverVideo"=dword:00000000
