Windows 10 which includes DirectX 12 includes the necessary run times for older versions of DirectX. So, you should be able to install older games using compatibility mode.

Launching your game.
I tried compatibility mode but it didn't make any difference, and unfortunately the registry edits didn't help either but that was something I hadn't thought of doing so it was worth a shot at least.
It's not an inherent issue with the 1803 update and DX10/11. I've have no problems with any games on any of the
Win10 versions (even 1709 which, until 1803 was released, was the update that many gamers reckoned was the
ultimate games breaker update).
Are you able to run Saints Row using the DX9 launch option ?
I don't have Startrek Online, bit Saints Row 3, and a few other games I have with Steam, need to have Steams
*'Verify integrity of game files'*tool run after every version/feature update, or they won't launch, or will crash after
the loading screens.
- The registry key value change is an interesting fix. I may help, but I've had no issues with 4.09....
- Anti-Virus programs seem to be causing issue a bit more since 1709. Try disabling your AV temporarily to verify
it's not silently blocking the games.
- You said 'reinstalled' your Nvidia drivers. Did you download the current driver from Nvidia, or are you
reinstalling an older driver ?

SR3 runs just fine in DX9 mode, and yes I made sure to download the latest drivers from nvidia. STO and a couple other games I just straight up uninstalled and reinstalled but it didn't do any good, so
I'm at a loss.
