Before worrying about Dolby Control Centre, you need to check that Sony supports Windows 8 on your Sony model, don't just take it for granted. If Sony don't have Windows 8 drivers for your model, you can't install Windows 8 on it (well technically you can, but don't expect all the hardware to work properly, if it works at all).
Check the drivers page for your model on the appropriate Sony Support website for your country:
