After one of the recent Windows 10 TP (Technical Preview) updates (I have now build 9879), Teamviewer remote connection stopped working and is either showing only a black screen or giving an error:

"The screen cannot be captured at the moment. This is probably due to fast user switching or a disconnected/minimized Remote Desktop session."

This seems to be due to a temporary issue between Windows 10 and Teamviewer service.

As a workaround do the following:

1) Open the “Start button” and use the search function to search for regedit and start it.
When asked if you want to allow the following program to make changes to this computer, click “YES”

2) In Regedit go to:


Right click and create a new DWORD (32-bit) Value

Replace “New Value #1” with “DisableDuplicationAPI”   (both without the ” Double Quotes” )

3) Double click the new DisableDuplicationAPI entry and set value data to 1

4) Reboot and Teamviewer should work again to connect remotely.
