The ATi Radeon HD 2000 Series was launched in 2006. Almost 10 years later I installed Windows 10 x64 on a machine with HD 2600 plugged in and the system had graphics hardware acceleration from the first reboot.
Stop the FUD.
HD2000 is from 2007
it works because Windows 10 accepts old, Vista+ drivers, you are probably running (from win update) a driver made for Windows 7, with no catalyst control center, like it's the case for my HD 4670
