Cannot install drivers for MTX65xx on Windows 10 64 bit for Telekom Puls Tablet
I finally solved it.

Put this command into the Windows Command Shell on Windows 10:

shutdown.exe /r /o /f /t 00


The computer will start to shut down and present you an option menu before he does. In the menu that follows, select "Troubleshooting", then "Advanced Options", then "Launch Parameters". Finally press "restart".

In the menu that appears after a restart, press 7 to allow for the installation of unsigned drivers.

Now open the adroid_winusb.inf in 

&lt;android_sdk&gt;/extras/google/usb_driver


and add

; Telekom Puls
%SingleAdbInterface% = USB_Install, USB\VID_1BBB&amp;PID_201D&amp;MI_01
%CompositeAdbInterface% = USB_Install, USB\VID_1BBB&amp;PID_201D&amp;REV_????&amp;MI_01
%SingleBootLoaderInterface% = USB_Install, USB\VID_1BBB&amp;PID_201D&amp;MI_01


to the end of the [Google.NTx86] and [Google.NTamd64] sections. Now save and right click the inf and select "install". After that, Windows 10 should recognize the tablet:
