I suspect that it is probably a driver issue. One of the DLL's (dynamic link libraries) use for video reproduction, possibly even the Adobe Flash driver is no longer used, discontinued in Windows 10.

The operating system is a money making machine, by upgrading and not maintaining total backward compatibility requires one to buy all new software. They also obsolete the hardware, requiring one to upgrade hardware also to maintain "compatibility".

However, I know that it doesn't help you in your situation.
