upd: i think I am quickly going from asking for help to reporting windows bugs. My other laptop (a bigger contrast with the C930 could not be made in terms of hardware) did pretty much the same thing. First the Netflix app goes out, then maybe 5 mins later the search glitch. This time under a clean install of Windows 10 Enterprise.
