It does say, "Addresses an issue that may cause some devices to stop responding or working when using applications, such as Cortana or Chrome, after installing the Windows 10 April 2018 Update." Did you get it yet? It is a lulu coming in, maybe it took 8 minutes of various spinning circles on various colored screens.
If that doesn't do it, we can BING your hardware IDs in Device Manager...
We can BING a few of those for a driver that may work. Also, there is this BING to look through...
BING of "TSSTcorp CDDVDW SU-208GB TM01"
If that is the actual device name that shows up in Device Manager, it does appear to be somewhat different than mine which does work.
