When the TechniSat SkyStar 2 TV PCI is first installed in Windows 10, it will work flawlessly. Once you switch the PC off and on again, it will not work any longer!
Workaround: Right click <Start> <Device Manager> <Network adapters> Doubble click <TechniSat DVB-PC TV Star PCI> <Power Management>, and then remove the mark at<Allow the computer to turn off this device to save power>.
Then it runs even when the computer comes back from "sleep" which was already a problem with Windows 7.
